The Inca Trail to Machu Picchu is one of the most iconic trekking routes in the world — a journey that blends adventure, history, and the breathtaking beauty of the Peruvian Andes. As the dry season begins to fade and the landscape takes on a softer, greener hue, September emerges as one of the most balanced and rewarding months to experience this legendary trail.
In September, the Inca Trail offers the perfect mix of good weather, fewer crowds, and exceptional visibility. The skies remain mostly clear, rainfall is still minimal, and the lush valleys begin to bloom again after the long Andean winter. It’s a month when trekkers can enjoy comfortable temperatures and vivid scenery, without the high-season congestion typical of June, July, and August.
Choosing the right tour company makes all the difference. Tunqui Expeditions — a trusted, Cusco-based operator — specializes in Inca Trail to Machu Picchu Tours that combine professionalism, safety, and authentic cultural immersion. Their licensed guides, ethical porters, and sustainable practices ensure every traveler experiences the Inca Trail not just as a hike, but as a spiritual and cultural journey through time.
Why Trek the Inca Trail in September?
Trekking the Inca Trail to Machu Picchu in September is one of the smartest choices for travelers seeking great weather, fewer crowds, and stunning scenery.
As the dry season transitions toward the beginning of the Andean spring, September offers a unique balance — clear skies, warm days, and a touch of green returning to the mountains after months of sunshine.
It’s a month that rewards both the adventurous and the mindful traveler: you’ll enjoy the full beauty of the Andes while avoiding the peak-season rush of July and August.
Here’s why September is an ideal time to hike the Inca Trail — and why booking your trek with Tunqui Expeditions
makes it even more special.
Excellent Trekking Weather
September marks the tail end of Peru’s dry season, bringing warm, sunny days and cool but manageable nights.
Average temperatures range from 18°C to 22°C (64–72°F) during the day and 5°C to 8°C (41–46°F) at night.
Unlike the rainy months ahead, September sees very little precipitation, keeping the trail dry, safe, and ideal for hiking.
It’s also a great month for clear mountain views and photography — especially from the Sun Gate (Inti Punku), where Machu Picchu glows beneath soft morning light.
With Tunqui Expeditions, all treks include professional guides, proper acclimatization, and comfortable camping gear to make the most of these perfect conditions.
Fewer Crowds, More Serenity
While June, July, and August are packed with international travelers, September brings a calmer, more peaceful atmosphere.
There are fewer hikers on the trail and smaller groups at key archaeological sites like Runkurakay, Sayacmarca, and Wiñay Wayna.
This makes September ideal for travelers who want to truly connect with nature, history, and the quiet magic of the Andes — without the distractions of peak-season crowds.
Lush and Vibrant Landscapes
By September, the Andes begin to recover from the long dry months.
Small wildflowers bloom, valleys regain a hint of green, and the air feels fresher. It’s a photographer’s dream: a landscape balanced between dry-season clarity and spring’s early vibrance.
Every step along the trail offers a new view — from misty cloud forests to open highlands bathed in sunlight.
Comfortable Temperatures and Easy Trekking
The Inca Trail in September is neither too hot nor too cold — ideal for multi-day hiking.
Nights are milder compared to July and August, so you can rest more comfortably at campsites like Pacaymayo or Phuyupatamarca.
With moderate temperatures and firm trail conditions, it’s one of the easiest months for first-time trekkers to adapt physically.
Better Permit Availability
Because the high-season rush begins to taper off, Inca Trail permits are easier to obtain in September compared to mid-year months.
Still, it’s wise to book early — especially if you’re planning your trip with a reputable operator like Tunqui Expeditions, who handles all permits, logistics, and Machu Picchu entry tickets.
This allows you to focus on the adventure, not the paperwork.
Authentic Andean Experiences
September is a transitional month for local communities. Farmers begin preparing for the upcoming rainy season, and villages celebrate the changing of the agricultural calendar with small festivals and rituals.
Traveling in September with Tunqui Expeditions gives you a chance to witness these authentic cultural traditions, from local markets in the Sacred Valley to community interactions along the route.
It’s a month filled with warmth — both from the sunshine and the people of the Andes.
Ideal for Post-Trek Exploration
Because weather conditions remain stable, September is also a great month to explore Cusco, the Sacred Valley, Rainbow Mountain, or Humantay Lake after completing your Inca Trail trek.
Tunqui Expeditions offers customized post-trek tours, so you can continue discovering Peru’s rich culture and landscapes at your own pace.
Weather on the Inca Trail in September
The Inca Trail to Machu Picchu in September offers some of the most comfortable and balanced weather conditions of the entire year. As the dry season in Peru begins to transition toward the rainy months, September provides clear skies, mild temperatures, and fewer crowds — making it one of the best times to trek.
For hikers looking for both pleasant weather and vibrant landscapes, September delivers the perfect mix.
Dry and Sunny Days
September is technically still part of the dry season in the Andes (May–September), meaning rainfall is minimal and the trail remains stable and safe.
Expect plenty of sunshine during the day, with gentle breezes and excellent visibility across the Sacred Valley and surrounding peaks.
- Average daytime temperatures: 18–22°C (64–72°F)
- Average nighttime temperatures: 5–8°C (41–46°F)
- Rainfall: Low, but occasional light showers may occur toward the end of the month
Bring a lightweight rain jacket just in case — the Andean weather can shift quickly, especially in the afternoons.
Clear Skies and Stunning Views
September’s weather offers superb visibility. You’ll wake up to brilliant blue skies and panoramic views of the Andes, the Sacred Valley, and ancient Inca ruins scattered along the trail.
The sunlight is softer than in the middle of the dry season, creating ideal conditions for photography — particularly at sunrise and sunset.
From the Sun Gate (Inti Punku), Machu Picchu often appears beneath a golden glow that photographers dream of capturing.
Pro Tip: September light adds warmth and depth to your Machu Picchu photos — bring extra camera batteries!
Cool, Comfortable Evenings
While the days are mild, the nights remain cool — though less cold than in July or August.
At high-altitude camps like Pacaymayo (3,600 m / 11,800 ft), temperatures can drop close to freezing, so thermal layers and a good sleeping bag are essential.
Tunqui Expeditions provides high-quality camping gear, warm sleeping mats, and professional porters to ensure you stay comfortable even at higher elevations.
Clear nights also mean starry skies — September is excellent for stargazing under the Milky Way.
Transitioning Landscapes
By September, the Andes begin to show the first signs of spring.
Small wildflowers start to bloom, grasslands regain a touch of green, and the valleys become more colorful. The environment feels fresh, alive, and photogenic — a welcome contrast to the dry, dusty conditions of July and August.
This subtle change in vegetation adds another layer of beauty to your trek, especially in the cloud forest section approaching Wiñay Wayna and Machu Picchu.
Minimal Rain, But Increasing Humidity
Although rain remains rare, humidity gradually increases as the region transitions into the wet season (October–March).
The air feels slightly warmer and denser, especially during the descent into the tropical cloud forest near Machu Picchu.
Tip: Pack light, moisture-wicking clothing and a rain cover for your backpack — just in case of a short afternoon drizzle.
Ideal Conditions for Trekking
Overall, September offers excellent trekking conditions: dry trails, manageable temperatures, and consistent weather.
It’s the perfect month for first-time trekkers or those seeking a balance between good weather and fewer crowds.
With Tunqui Expeditions, you’ll have a local guide team monitoring conditions daily, ensuring your hike remains safe and enjoyable from start to finish.

Pros of Hiking the Inca Trail in September
September is often described as a hidden gem month for trekking the Inca Trail to Machu Picchu — a time when conditions are near-perfect, yet crowds have started to thin after the peak tourist rush. It’s a month that strikes a beautiful balance between ideal weather, vibrant landscapes, and peaceful trails.
Here are the top advantages of hiking the Inca Trail in September, according to the expert local guides at Tunqui Expeditions.
Perfect Trekking Weather
September sits right between the dry and wet seasons, offering some of the most comfortable weather of the year.
- Days: Warm, sunny, and dry (18–22°C / 64–72°F)
- Nights: Cool but not freezing (5–8°C / 41–46°F)
These moderate temperatures make hiking more enjoyable and less physically demanding compared to the colder months of June and July.
With Tunqui Expeditions, you’ll be equipped with quality camping gear and professional support to make the most of these favorable conditions.
Breathtaking Views and Clear Skies
September offers excellent visibility for both trekkers and photographers.
The skies remain mostly clear, providing uninterrupted views of:
- Snow-capped peaks like Salkantay and Veronica
- Verdant valleys and ancient Inca ruins
- The sunrise at Inti Punku (Sun Gate) over Machu Picchu
The sunlight in September is softer than in mid-year, giving photos a warm, golden tone — ideal for capturing the Andes at their best.
The Andes Begin to Bloom
After months of dry weather, the Andes start to come alive again in September.
The first hints of spring appear — green grasses, small wildflowers, and fresher air in the highlands.
This combination of dry trails and renewed greenery makes the trek more visually stunning and refreshing.
It’s one of the most scenic months to witness the transition from the dry Andes to the lush valleys below.
Fewer Crowds Than Peak Season
While still popular, September is noticeably quieter than June, July, and August.
You’ll find:
- More space at campsites and viewpoints
- Less waiting time at archaeological sites
- A more peaceful atmosphere overall
If you’re looking for the perfect balance between good weather and fewer crowds, September is the sweet spot.
Tunqui Expeditions offers small group tours, ensuring a more personal and immersive experience on the trail.
Comfortable Camping Conditions
Cool nights and mild evenings make camping in September more comfortable than in colder months.
You’ll enjoy:
- Warm meals under clear skies
- Stunning sunsets over the Andes
- Crisp, clean air for deep rest
Tunqui Expeditions provides high-quality tents, sleeping mats, and nutritious Andean meals — ensuring comfort after each day of hiking.
Few experiences compare to stargazing beneath the Milky Way from your campsite in the Andes.
Easier Permit Availability
Since September marks the end of the high season, it’s often easier to find available Inca Trail permits compared to earlier months.
This gives travelers more flexibility when planning their trip.
Tip: Even so, permits can still sell out quickly — always book in advance through a licensed operator like Tunqui Expeditions, who handles all permits, tickets, and logistics for your trek.
Authentic Andean Culture and Festivals
September marks the beginning of the Andean agricultural cycle, with small local festivals and rituals held throughout Cusco and the Sacred Valley.
You might witness offerings to Pachamama (Mother Earth) or community celebrations marking the change of season.
Traveling with Tunqui Expeditions gives you the chance to connect with these local traditions — a meaningful cultural complement to your trek.

Cons of Hiking the Inca Trail in September
While September is one of the most comfortable and scenic months to hike the Inca Trail to Machu Picchu, it’s not without its minor challenges.
Understanding these potential downsides can help you prepare — and ensure your trek remains smooth, safe, and unforgettable.
Here are the main cons of hiking the Inca Trail in September, along with advice from the expert guides at Tunqui Expeditions
on how to manage them.
Still Part of the Tourist Season
Although the large crowds of June, July, and August begin to thin out, September remains a busy month on the Inca Trail.
It’s still dry season, which means that many travelers continue to visit Machu Picchu before the rains return.
As a result:
- Inca Trail permits can still sell out weeks or even months in advance.
- Campsites like Wiñay Wayna may feel lively with groups.
- Cusco and Aguas Calientes remain active tourist hubs.
Tip: Book early with Tunqui Expeditions to secure your trail permit and enjoy smaller, well-organized group tours for a more personal experience.
Occasional Showers Toward the End of the Month
September is a transitional month between Peru’s dry and rainy seasons.
While the first half of the month is typically clear and dry, short afternoon showers may start to appear toward the end of September, especially near the cloud forest sections of the trail.
Solution: Pack a lightweight rain jacket and a waterproof backpack cover.
Tunqui Expeditions monitors weather conditions daily and adjusts itineraries when necessary for your comfort and safety.
Cool Nights at Higher Elevations
Even though daytime temperatures are mild, nights can still get cold — especially at high-altitude camps like Pacaymayo (3,600 m / 11,800 ft) and Phuyupatamarca (3,670 m / 12,040 ft).
Temperatures may drop to 0°C–5°C (32–41°F) overnight.
Without proper gear, sleeping can be uncomfortable.
Tip: Bring a warm sleeping bag and thermal layers.
When you book with Tunqui Expeditions, quality sleeping mats and insulated tents are included for a cozy night’s rest.
Dust and Dry Air
By the end of the dry season, some sections of the Inca Trail can become dusty, particularly the open highlands.
The air is also relatively dry, which may cause mild irritation for some trekkers.
Tip: Use a neck gaiter or buff to protect your face and drink water frequently to stay hydrated.
Your guides from Tunqui Expeditions will provide regular hydration stops and ensure you maintain a comfortable pace.
High Demand for Accommodations and Flights
Although September is not as busy as peak months, it still falls within Peru’s popular travel period.
Flights to Cusco and hotels in the Sacred Valley may remain at higher-than-average prices.
Tip: Reserve early — Tunqui Expeditions can assist with full travel arrangements, including hotel recommendations and transportation, ensuring a smooth pre- and post-trek experience.
Variable Weather at the End of the Month
As the rainy season approaches, weather in late September can be unpredictable.
You may experience warm sunshine one hour and overcast skies the next — especially closer to Machu Picchu’s tropical climate zone.
Tip: Layer your clothing.
Bring a light rain poncho, quick-dry clothing, and a positive mindset — these quick changes often make the scenery even more dramatic.
Summary: Cons of Hiking the Inca Trail in September
| Challenge | Description | Solution |
|---|---|---|
| Moderate crowds | Still part of the tourist season | Book early with Tunqui Expeditions |
| Occasional rain | Short showers near month’s end | Bring a rain jacket & pack cover |
| Cold nights | Freezing temps at high camps | Pack warm layers & sleeping bag |
| Dusty trails | Dry air in higher regions | Use a gaiter & stay hydrated |
| High prices | Demand for flights/hotels | Book in advance for best deals |
| Variable weather | Late-month transitions | Layer clothing for quick changes |
While September brings a few manageable challenges — like cool nights, some trail dust, and brief showers — the overall experience remains outstanding.
The weather is still dry, the scenery begins to bloom, and the atmosphere on the trail is peaceful yet lively.
With the guidance of Tunqui Expeditions, you can easily overcome these minor inconveniences. Their expert local team ensures every detail — from camping comfort to weather preparedness — is handled with care, allowing you to focus on the breathtaking beauty of the Andes.
Recommendations for Hiking the Inca Trail in September
Trekking the Inca Trail to Machu Picchu in September is one of the most rewarding experiences in Peru — combining mild weather, vibrant landscapes, and a calmer atmosphere after the busy high season.
However, to make the most of your journey, a bit of preparation and smart planning go a long way.
Here are the top recommendations from the expert local guides at Tunqui Expeditions to ensure your September trek is safe, comfortable, and unforgettable.
Book Your Inca Trail Permit in Advance
Even though September is less crowded than July or August, permits still sell out quickly due to Peru’s limited daily quota of 500 people per day (including guides and porters).
Recommendation: Reserve your spot at least 3–4 months in advance with a licensed operator like Tunqui Expeditions, who handles all government permits, Machu Picchu tickets, and logistics on your behalf.
If permits are gone, Tunqui Expeditions offers stunning alternative routes such as the Salkantay Trek, Lares Trek, or Choquequirao Trek — each with equally breathtaking scenery and cultural experiences.
Spend a Few Days Acclimatizing in Cusco
Cusco sits at 3,400 meters (11,150 ft), and the Inca Trail’s highest point — Dead Woman’s Pass (4,215 m / 13,828 ft) — can be physically challenging if you’re not used to the altitude.
Plan to arrive 2–3 days before your trek to acclimatize.
During this time:
- Stay hydrated and drink coca tea.
- Avoid alcohol and heavy meals.
- Take light walks around Cusco or visit the Sacred Valley for gentle altitude adjustment.
Tunqui Expeditions offers pre-trek acclimatization tours designed to help you adapt comfortably.
Pack Smart and Light
September weather is stable but can change quickly in the Andes. You’ll experience warm days, cool nights, and occasional light showers.
Essential items to pack:
- Light, moisture-wicking hiking clothes
- Fleece jacket or down layer for cold evenings
- Thermal base layers for camping nights
- Rain jacket or poncho
- Hat, sunglasses, and high-SPF sunscreen
- Trekking poles (with rubber tips)
- Refillable water bottle or hydration pack
Tunqui Expeditions provides tents, sleeping mats, and duffel bags for porters to carry, so you can hike comfortably with only a daypack.
Stay Hydrated and Protect Yourself From the Sun
The Andean sun is intense year-round, even in cooler months. Dehydration and sunburn are common issues for unprepared trekkers.
Safety recommendations:
- Drink 2–3 liters of water per day.
- Use electrolyte packets to stay energized.
- Apply SPF 50+ sunscreen regularly.
- Protect your lips with UV lip balm.
Tunqui Expeditions provides safe boiled water daily and reminds hikers to stay hydrated throughout the trek.
Train Before You Go
The Inca Trail is moderate but demanding — with steep climbs, stairs, and high-altitude sections.
Prepare your body with 4–6 weeks of regular exercise before your trip, focusing on:
- Hiking or stair training
- Cardiovascular endurance
- Leg strength and balance
You don’t need to be a professional athlete, but good fitness will make the experience far more enjoyable.
Respect the Trail and Local Culture
The Inca Trail is both a UNESCO World Heritage Site and a sacred path for Andean communities. Show respect by:
- Carrying out all waste and avoiding plastic bottles.
- Supporting local artisans and fair-wage porters.
- Asking permission before photographing people.
- Learning a few Quechua words — locals appreciate it!
Tunqui Expeditions practices sustainable and ethical trekking, ensuring fair treatment for porters and minimal environmental impact.
Embrace the Local Festivities
September is a vibrant month in the Andes. Small towns and villages host spring festivals and cultural celebrations honoring Pachamama (Mother Earth) and the new agricultural season.
If your travel dates align, you might witness traditional dances, music, and local food fairs in Cusco or the Sacred Valley.
Tunqui Expeditions can arrange cultural add-ons to your trek — perfect for travelers wanting a deeper connection with Andean life.
Prepare for Minor Weather Changes
Although September is mostly dry, light rain showers can appear near the end of the month.
Pack quick-drying clothes, a compact rain cover, and a positive mindset — the rain often brings magical rainbows and misty mountain views.
Your guides from Tunqui Expeditions constantly monitor the weather and adjust the itinerary for maximum comfort and safety.
Capture the Moment
The lighting in September is spectacular — softer than in peak winter months.
Bring a camera or smartphone, extra batteries, and a power bank, as charging options on the trail are limited.
Pro tip: The golden sunrise at Machu Picchu from the Sun Gate (Inti Punku) in September is a photographer’s dream.
Summary: Key Recommendations for September hikers
| Recommendation | Why It Matters |
|---|---|
| Book early | Secure your Inca Trail permit |
| Acclimatize | Prevent altitude sickness |
| Pack smart | Be ready for all temperatures |
| Stay hydrated | Avoid fatigue and altitude issues |
| Train beforehand | Make the trek more enjoyable |
| Respect culture | Support sustainability and locals |
| Enjoy festivals | Experience authentic Andean life |
| Prepare for light rain | Stay dry and positive |
Hiking the Inca Trail in September is one of the best travel decisions you can make — ideal weather, open skies, and a peaceful trail await.
With thoughtful preparation and the expert support of Tunqui Expeditions, you’ll experience the Inca Trail the way it’s meant to be — safe, authentic, and full of wonder.
Is It Safe to Visit Machu Picchu in September?
Yes — it’s completely safe to visit Machu Picchu in September.
In fact, it’s one of the best and most reliable months of the year to explore this world wonder. The weather is stable, the crowds are smaller than during peak season, and the region’s tourism infrastructure operates at full capacity, ensuring a smooth and enjoyable travel experience.
Here’s why September is a safe and comfortable month to visit Machu Picchu and hike the Inca Trail, with expert guidance from Tunqui Expeditions.
Stable, Pleasant Weather
September falls just after Peru’s driest months, offering clear skies, mild temperatures, and very little rain.
You’ll enjoy sunny days perfect for hiking, sightseeing, and photography, while avoiding the heavy rains that arrive later in the year.
- Average daytime temperature: 18–22°C (64–72°F)
- Average nighttime temperature: 5–8°C (41–46°F)
Because the ground remains dry and trails are firm, the risk of slips, landslides, or muddy paths is very low, making conditions ideal for both hiking and visiting the archaeological site.
With Tunqui Expeditions, weather conditions are monitored daily to ensure your trek remains safe and comfortable.
Reliable Transport and Logistics
During September, trains, buses, and flights run on regular schedules, with minimal weather disruptions.
The train from Cusco or Ollantaytambo to Aguas Calientes (the town at the base of Machu Picchu) operates smoothly.
- Roads are in excellent condition thanks to the dry season.
- The Inca Trail and alternative routes (Salkantay, Lares, Choquequirao) remain fully open and well-maintained.
Tunqui Expeditions manages all logistics — including transportation, permits, and Machu Picchu entry tickets — ensuring a safe and worry-free experience.
Well-Regulated Tourism Infrastructure
Machu Picchu is one of the most professionally managed archaeological sites in South America.
Visitor access is carefully controlled with timed entry tickets, designated circuits, and trained guides to preserve both safety and the site’s integrity.
Tunqui Expeditions, a licensed local operator, adheres strictly to all Peruvian government regulations and environmental standards. You’ll trek and visit under expert supervision, with guides trained in first aid and emergency response.
Health and Altitude Safety
The biggest challenge for some visitors isn’t security — it’s altitude adjustment.
Cusco (3,400 m / 11,150 ft) is much higher than Machu Picchu (2,430 m / 7,972 ft), and altitude sickness can affect travelers who don’t acclimatize properly.
Safety tips:
- Spend 2–3 days acclimatizing in Cusco or the Sacred Valley before your trek.
- Drink plenty of water and coca tea.
- Avoid alcohol during your first few days.
- Trek at a steady pace — there’s no rush to reach each campsite.
Tunqui Expeditions includes pre-trek briefings, acclimatization recommendations, and guides trained to recognize and manage altitude-related symptoms.
Low Crime Rate in Tourist Areas
The main tourist destinations — Cusco, the Sacred Valley, Aguas Calientes, and Machu Picchu — are considered very safe.
Petty theft is rare, and violent crime is extremely uncommon in tourist zones.
Safety advice:
- Use official taxis or transfers arranged by your tour company.
- Keep valuables secure and avoid leaving items unattended.
- Follow your guide’s instructions, especially at busy viewpoints.
Tunqui Expeditions provides secure transport and experienced local staff who know the region inside and out.
Minor Weather Variability at Month’s End
By late September, a few light afternoon showers may appear as the Andes transition toward the rainy season.
However, these are typically brief and add to the region’s beauty — with misty mountains and rainbows over Machu Picchu.
Carry a compact rain jacket and waterproof cover for your backpack — simple precautions to stay comfortable.
Quick Safety Overview for September
| Factor | Safety Level | Details |
|---|---|---|
| Weather | Excellent | Dry, clear, and predictable |
| Transportation | Excellent | Trains and buses fully operational |
| Trail Conditions | Excellent | Firm, dry, and well-maintained |
| Health Risk | Low | Manageable with acclimatization |
| Security | High | Very low crime in tourist zones |
| Weather Variability | Mild | Occasional brief showers late month |
Final Thoughts
Yes — it’s absolutely safe to visit Machu Picchu in September.
With ideal weather, stable transportation, and professional tourism infrastructure, it’s one of the most reliable months to explore the Andes and experience this ancient wonder.
When you travel with Tunqui Expeditions, you gain more than just safety — you gain peace of mind. Their certified guides, ethical porters, and sustainable practices ensure your journey is secure, meaningful, and deeply connected to the spirit of the Andes.
Best Time of Year For Inca Trail Trek
Trekking the Inca Trail to Machu Picchu is one of the world’s most unforgettable adventures — and choosing the right time of year to go can make all the difference between a good trip and a truly spectacular one.
Because the Inca Trail passes through several different microclimates in the Andes Mountains of Peru, weather conditions and visitor experiences vary significantly throughout the year.
Here’s everything you need to know to decide the best time to hike the Inca Trail, with expert insights from the local specialists at Tunqui Expeditions.
Dry Season (May to September): The Best Time to Trek
Most trekkers agree that the dry season — from May through September — is the best time of year to hike the Inca Trail.
During these months, the weather is clear, the trails are dry, and the visibility of the Andes is at its most breathtaking.
Why It’s Ideal:
- Minimal rainfall makes for safe, stable trekking conditions.
- Bright sunshine and clear blue skies perfect for photography.
- Comfortable temperatures during the day (18–22°C / 64–72°F).
- Stunning sunrise at Machu Picchu, especially in June and July.
Peak months: June, July, and August are the most popular — and for good reason. July, in particular, offers the most consistent weather and the best visibility.
However, because these months are high season, trail permits sell out fast. You’ll need to book 4–6 months in advance with a licensed operator like Tunqui Expeditions to secure your spot.
Rainy Season (November to March): The Quiet Alternative
If you prefer solitude and don’t mind a little rain, the wet season (November–March) can offer a more peaceful experience — but with more challenges.
Considerations:
- Frequent rain showers make trails muddy and slippery.
- Limited visibility due to fog and clouds.
- Inca Trail closes every February for maintenance and conservation.
Still, this period brings lush green landscapes, fewer crowds, and lower prices. For travelers seeking a less crowded but equally scenic trek, alternative routes like the Salkantay Trek or Lares Trek are excellent options — both available year-round with Tunqui Expeditions.
Shoulder Seasons (April & October): The Sweet Spot
For many experienced trekkers, April and October represent the perfect balance between good weather and fewer crowds.
Advantages:
- Mild temperatures and some greenery from recent rains.
- Smaller groups on the trail, creating a calmer atmosphere.
- Greater permit availability compared to the peak season.
These months are great for travelers looking for photogenic landscapes without the intensity of high-season crowds.
Quick Comparison Chart
| Month | Weather | Trail Conditions | Crowds | Best For |
|---|---|---|---|---|
| April | Mild & clear | Drying after rains | Moderate | Balance of weather & crowds |
| May | Sunny & dry | Excellent | High | Start of dry season |
| June | Clear & cool | Excellent | Very high | Festivals & best views |
| July | Sunny & crisp | Perfect | Very high | Ideal weather, vibrant energy |
| August | Cool & dry | Excellent | High | Peak trekking conditions |
| September | Warming up | Stable | Moderate | Fewer crowds |
| October | Mild & green | Slight rain | Moderate | Great balance |
| Nov–Mar | Rainy & humid | Muddy | Low | Off-season adventurers only |
Expert Tip: Choose Based on Priorities
Your “best” time to hike the Inca Trail depends on what kind of experience you want:
| Priority | Best Time to Go |
|---|---|
| Perfect weather & photography | June–July |
| Fewer crowds & good weather | April or October |
| Budget-friendly travel | November–March |
| Cultural festivals (Inti Raymi & Fiestas Patrias) | June–July |
The best time of year to trek the Inca Trail is during the dry season, particularly May to September, when conditions are safest and the views are at their most stunning.
However, every season offers its own beauty — whether it’s the vibrant greenery of the rainy months or the peaceful atmosphere of the shoulder seasons.
By booking early and traveling with a trusted local operator like Tunqui Expeditions, you’ll ensure your journey is not only unforgettable but also safe, responsible, and culturally enriching.

Things to Know Before Hiking the Inca Trail in September
The Inca Trail to Machu Picchu in September is one of the most balanced and rewarding times to hike this legendary route. The weather is mild, the landscapes begin to bloom, and the crowds start to thin — but smart preparation is key to making the most of this perfect trekking month.
Here are the most important things to know before hiking the Inca Trail in September, based on expert advice from Tunqui Expeditions, a trusted local operator in Cusco specializing in authentic and sustainable trekking experiences.
Permits Are Still Limited — Book Early
Even though September is slightly less crowded than July or August, the Inca Trail permit system still limits access to 500 people per day, including porters and guides.
Recommendation:
Book your trek 3–4 months in advance with a licensed operator like Tunqui Expeditions, who handles all permits, Machu Picchu entry tickets, train transfers, and camping logistics.
If Inca Trail permits are sold out, Tunqui Expeditions also offers stunning alternative routes such as the Salkantay, Lares, or Choquequirao treks — all leading to Machu Picchu and available year-round.
Acclimatization Is Essential
Cusco sits at 3,400 meters (11,150 ft), while the highest point of the Inca Trail — Dead Woman’s Pass — reaches 4,215 meters (13,828 ft).
Altitude can affect even experienced hikers, so acclimatizing properly is vital.
Tips from Tunqui Expeditions:
- Spend 2–3 days in Cusco before starting your trek.
- Drink plenty of water and coca tea.
- Avoid alcohol and heavy meals.
- Take light walks or city tours to help your body adjust.
Tunqui Expeditions offers pre-trek acclimatization programs and orientation briefings to prepare you physically and mentally.

Stay Hydrated and Sun-Protected
The Andean sun can be intense even when temperatures feel mild. Combined with dry mountain air, dehydration can sneak up on hikers.
Pro Tips:
- Drink 2–3 liters of water daily.
- Use electrolyte powder or hydration salts.
- Apply SPF 50+ sunscreen and UV lip balm regularly.
- Wear sunglasses and a sun hat during daytime hikes.
Tunqui Expeditions provides safe boiled water at all campsites to refill your bottles daily.
Train Before You Arrive
The Inca Trail is not extremely technical, but it’s a multi-day, high-altitude hike that involves steep climbs, long stairways, and endurance.
Start preparing 4–6 weeks before your trek by:
- Doing regular cardio (walking, running, or hiking)
- Practicing on hills or stair climbs
- Strengthening your legs and core
- Wearing and breaking in your hiking boots
Being fit will help you enjoy the journey more — and reduce the risk of fatigue or injury.
Expect Cool Nights at Camp
While days are warm and pleasant, nights can still dip to 0–5°C (32–41°F) at high elevations.
Tips:
- Bring thermal clothing and a good sleeping bag (rated for at least -5°C / 23°F).
- Wear warm socks and a beanie for sleeping.
- Use hand warmers if you get cold easily.
Tunqui Expeditions provides insulated tents, sleeping mats, and warm Andean meals, ensuring you stay comfortable at every camp.
Respect the Environment and Local Communities
The Inca Trail is both a UNESCO World Heritage Site and a sacred cultural path.
Preserve it by:
- Carrying out all your trash.
- Avoiding single-use plastics.
- Staying on marked trails.
- Treating porters and locals with kindness and respect.
Tunqui Expeditions is committed to sustainable tourism, ensuring fair wages for porters, eco-friendly practices, and positive community impact.
