Inca Trail guide: how to plan your trek to Machu Picchu
This Inca Trail guide comes from Inca Trail Reservations, which has guided trekkers to Machu Picchu since 2006, and shows you how the trek works and what to plan at each step. Each section gives the short answer, then links to a detailed guide when you need more.
What Is the Inca Trail?
The Inca Trail is a 26-mile (42 km) ancient hiking route through the Peruvian Andes that ends at Machu Picchu. Built by the Inca Empire as a pilgrimage path, it crosses three mountain passes, reaches 4,215 meters at its highest point, and requires government-issued permits limited to 500 people per day.
TL;DR: Inca Trail Key Facts
- Distance: 26 mi / 42 km over 4 days, 3 nights (classic route)
- Max elevation: 4,215 m (13,828 ft) at Dead Woman’s Pass on Day 2
- Annual closure: The trail closes every February for maintenance
- Daily permit cap: 500 permits total (~200 trekkers + ~300 staff)
Why Hike the Inca Trail
Day visitors reach Machu Picchu by bus from Aguas Calientes. Trekkers arrive on foot, down the stone path through the Sun Gate (Inti Punku), and that arrival is the reason to do the trek. It costs you a 4:00 am wake-up on Day 4 and about an hour in a dark queue at the checkpoint, which opens at 5:30.
In return you get 42 km of trail, three high passes and six archaeological sites on foot. Only 500 people may enter the trail each day, and roughly 200 of them are trekkers; the rest are guides, porters and cooks. That cap is why June to August permits sell out five to six months ahead.
It is also the least comfortable way to get there. Most camps have squat toilets, there are no hot showers for four days, and the Day 2 night at Pacaymayo is cold enough that we tell trekkers to pack for −2 °C. Day 2 itself is 11 km and 7 to 8 hours, including a 1,200 m climb to Dead Woman’s Pass at 4,215 m (13,828 ft), the highest point of the trek.
The sections below cover permits and booking, training, the day-by-day route, packing and cost. Each gives the short answer and links to the full guide.

History of the Inca Trail
Why the Trail Exists
The Inca Trail is a short branch of the Qhapaq Ñan, the road network that tied the empire together across six countries and was inscribed as a UNESCO World Heritage site in 2014. For the whole network, see Top Hiking Trails in South America: The Qhapaq Ñan.
Why the Inca routed a path over three high passes to Machu Picchu is interpretation, not settled fact. The common reading is ceremonial travel: the Inca held mountains (Apus) sacred, and merchants and chasquis (messengers) used other roads. Archaeologists still debate what Machu Picchu itself was, a royal estate, a sacred site or an astronomical observatory.
Rediscovery: From Hiram Bingham to Today
American explorer Hiram Bingham “discovered” Machu Picchu in 1911, though local farmers had known of it for generations. Between 1913 and 1915, Bingham’s expeditions cleared the overgrown trail, revealing the stone pathways and ruins that trekkers walk today.
The trail remained relatively obscure until the 1970s, when adventurous backpackers began walking it. By the 1990s, its popularity had grown to the point of causing environmental damage. The Peruvian government responded in 2001 with the permit system still in place today.
The cap is the rule that matters today: 500 people a day, staff included, under a regulation the Ministry of Culture approved in 2017 and amended in November 2025 and September 2026. The rules and regulations guide has the detail.

Inca Trail Routes: 2-Day, 4-Day, and Extended Options
The 4-day Classic is the full trek. The 2-day Short Inca Trail swaps the passes and the camping for a hotel bed and a 12 km walk. Extended versions add days for acclimatization.
The Classic 4-Day Inca Trail
Four days, three nights, camping the whole way, and a Day 4 arrival at Machu Picchu on foot through the Sun Gate.
For specific trail data and GPS coordinates, see our Inca Trail trail details or browse all Cusco trails.
The Numbers:
- Distance: 26 miles (42 km)
- Duration: 4 days, 3 nights
- Highest elevation: 4,215m (13,828 ft) at Dead Woman’s Pass
- Total ascent: 2,065m (6,774 ft)
- Total descent: 2,265m (7,431 ft)
The 4-day route passes six archaeological sites that most Machu Picchu visitors never see: Llactapata, Runkurakay, Sayacmarca, Phuyupatamarca, Wiñay Wayna and Inti Punku. You cross three mountain passes, move from high-altitude grassland to cloud forest, and arrive at Machu Picchu through the Sun Gate at sunrise.
Best for: trekkers who can give four days, have moderate fitness and want the full route.
View our Classic 4-Day Inca Trail Tour for full itinerary details.
The Short 2-Day Inca Trail
The 2-day option covers the Km 104 section of the trail, including Wiñay Wayna. Our Short Inca Trail vs Classic Inca Trail table puts the two side by side, including the separate daily caps (250 on the Km 104 route, 500 on the classic).
The Numbers:
- Distance: 7.5 miles (12 km)
- Duration: 2 days, 1 night (or single-day option)
- Starting point: Km 104 (accessible by train)
- Highest elevation: 2,700m (8,858 ft)
Hotel pickup in Cusco is around 5:00 am. A train takes you from Ollantaytambo to Km 104, where you cross the Urubamba at Chachabamba and climb through cloud forest for about three hours to Wiñay Wayna. The walk (12 km, 6–7 hours) continues past the Sun Gate, where you stop for photos, and the day ends in Aguas Calientes with a night in a hotel. Machu Picchu comes the next morning on the first bus, about 25 minutes up the switchbacks.
Best for: travelers with limited time, anyone nervous about altitude (the high point is 2,700 m), families with children, and anyone whose 4-day dates sold out.
The 2-Day Short Inca Trail Tour covers all the details.
4-Day vs. 2-Day Inca Trail: Pros and Cons
| Feature | Classic 4-Day | Short 2-Day |
|---|---|---|
| Distance | 26 mi (42 km) | 7.5 mi (12 km) |
| Duration | 4 days, 3 nights | 2 days, 1 night |
| Highest point | 4,215m (Dead Woman’s Pass) | 2,700m |
| Camping | Yes (3 nights) | No (hotel in Aguas Calientes) |
| Sun Gate | Day 4, at sunrise, on foot | Day 1 afternoon, photo stop |
| Permit required | Yes | Yes |
| Difficulty | Moderate-Challenging | Moderate |
| Best for | Full experience seekers | Limited time / lower fitness |
4-Day Classic Inca Trail Pros:
- Arrive at the Sun Gate at sunrise on foot, after three nights of camping
- Six archaeological sites on foot, including four the 2-day route skips (Llactapata, Runkurakay, Sayacmarca, Phuyupatamarca)
- Three mountain pass crossings including Dead Woman’s Pass
- Transition through multiple ecosystems: grassland, alpine, cloud forest
- Camps at Wayllabamba, Pacaymayo and Wiñay Wayna, with porters and a cook doing the set-up
4-Day Cons:
- Requires 4 days away from other Peru activities
- Permits sell out months in advance for peak season
- Physically demanding, especially Day 2 at altitude
- Cold overnight temperatures at high-altitude camps
- More expensive than the 2-day option
2-Day Short Inca Trail Pros:
- Covers Chachabamba, Wiñay Wayna and a Sun Gate photo stop in one 12 km, 6–7 hour day
- Sleeps in a hotel in Aguas Calientes instead of a tent
- Lower altitude (max 2,700m vs. 4,215m), reducing altitude sickness risk
- Easier to book with better permit availability
- Suitable for families, older travelers, and those with limited time
2-Day Cons:
- Skips four of the six sites on the classic route (Llactapata, Runkurakay, Sayacmarca, Phuyupatamarca)
- No Dead Woman’s Pass crossing or high-altitude pass experience
- You enter Machu Picchu by bus on Day 2, not on foot through the Sun Gate at sunrise
- Starts by train to Km 104 rather than hiking from Km 82
Extended 5-Day and 7-Day Options
Extended versions add camping nights and archaeological detours. Daily distances shrink, and you get more time to adapt before the 4,215 m pass.
Private vs. Group Treks
The regulation allows up to 16 trekkers in a group. Budget operators often fill that number; our groups average 8, with one guide for every six trekkers.
Group treks cost less and mean sharing campsites and a dining tent with other travelers.
Private treks let you set the pace and often come with better camping equipment, at a higher price.
Pick your route: 4-Day Classic or 2-Day Short Inca Trail. Only the 4-day enters Machu Picchu on foot through the Sun Gate.
Best Time to Hike the Inca Trail
The dry season, April to October, brings clear skies and a firm trail; June to August have the best weather and sell out 5–6 months ahead. April–May and September–October balance good weather with easier permits, November to March is wet, and the trail closes every February for maintenance (see the Inca Trail rules and regulations). Our guide to the best time to hike the Inca Trail goes month by month.
Inca Trail Permits: How the System Works
The permit system confuses first-time planners. Here’s the short version, plus where to check live availability and the full regulations.
Understanding the Permit System
The Ministry of Culture sells the permits, through its TuBoleto platform, to licensed agencies only. The regulation caps routes 1 to 4, which include the classic trek, at 500 people a day, covering everyone on the trail: trekkers, guides, porters and cooks. After staff, roughly 200 places go to trekkers. SERNANP, Peru’s protected-areas service, licenses the agencies and runs control posts on the trail.
Permits are passport-name bound, non-transferable, and non-refundable. The name and passport number on the permit must match the document you present at the Km 82 checkpoint. Typos void the permit. Independent hiking has been prohibited since 2001; only licensed Cusco-based operators can apply on your behalf. Since September 2026 a permit can only be bought with immediate full payment, which is why we take a $250 deposit and apply the moment sales open for your date. Porter load limits and tipping are in our porter etiquette guide.
The Main Rules in Brief
- Organized groups only: every group walks with a licensed agency and an official guide, who may not leave the group.
- Original ID at every control post: trekkers, guides and porters register with their original documents.
- Hours: groups enter between 5:00 am and 2:00 pm, and nobody walks the trail between 6:00 pm and 5:00 am.
- Banned: drones, glass containers, alcohol, and trekking poles with uncapped metal tips. All rubbish is carried out.
- Closures: the trail is closed every February, and the Ministry can close it at short notice. Entry was suspended on 18 August 2026 after heavy rain caused landslides, and the Ministry reported groups back on the trail on 6 September.
The full list, with the legal sources, is in the Inca Trail rules and regulations guide.
How Far in Advance to Book
Peak (June–August): 5–6 months ahead. The last two seasons went on sale in November (4 November 2024 for 2025, 17 November 2025 for 2026). The 2027 date had not been announced as of 2 November 2026, so book with a deposit and let the agency apply on day one; the permits guide carries the current status.
Shoulder (April–May, September–October): 3–4 months ahead. Still some flexibility but not last-minute.
Low (November, December, March): 1–3 months ahead. Permits often remain, but nothing is guaranteed.
For a live date-by-date calendar, see our live permit availability for your dates.

Training for the Inca Trail
The classic 4-day trek is moderate to challenging: four days above 2,700 m, thousands of stone steps and a high point of 4,215 m at Dead Woman’s Pass, with no technical climbing. Three months of stair climbing, hill hikes with a loaded daypack and back-to-back long walks prepare most first-time trekkers, together with at least 48 hours in Cusco to acclimatize. Follow our 12-week Inca Trail training plan, and see the Inca Trail difficulty guide for how hard each day is.
The Inca Trail Day by Day
Day 1 follows the Urubamba valley from Km 82 to Wayllabamba (11 km). Day 2 is the hardest, climbing to Dead Woman’s Pass at 4,215 m; Day 3 is the longest, 16 km past a string of Inca sites; and on Day 4 you walk through the Sun Gate at sunrise for a guided tour of Machu Picchu. The Inca Trail itinerary goes hour by hour, with separate guides to the campsites, the archaeological sites and the wildlife along the way.
Getting to the Trail and Back
Your operator collects you from your Cusco hotel between 5:30 and 6:00 am and drives you to the Km 82 trailhead in the Sacred Valley, where you register at the checkpoint with your original passport.
On Day 4 you walk down through the Sun Gate and take a guided tour of Machu Picchu of about two hours. Then comes the bus down the switchbacks to Aguas Calientes (about 25 minutes) and the train back: train and bus via Ollantaytambo to Wanchaq station, or train all the way to San Pedro or Poroy station, depending on the departure. On the round-trip itinerary you are back in Cusco between 5:30 pm and 12:45 am.
The return to Cusco is not in the $749 price. In the booking box, the Expedition train and bus are a $70 add-on, or $51 by train to Hidroelectrica and a 6-hour bus, and the bus down from Machu Picchu is extra. The $819 round trip includes the bus down and the Expedition train and bus.
What to Pack for the Inca Trail
Your operator provides the tents, meals and porters; a porter carries one duffel of up to 7 kg of your gear, which you only reach at camp. You bring your passport, broken-in waterproof boots, a 20–30 litre daypack, a headlamp, layers for 20 °C days and nights near freezing, and a sleeping bag rated to −10 °C (we rent them for $25, and trekking poles for $30 a pair). The full Inca Trail packing list covers every item.
Staying Safe and Healthy on the Inca Trail
The trail is well-managed and thousands complete it safely each year. Preparation reduces the small risks that exist. Read our health and safety guide for detailed protocols.
Altitude Sickness: Prevention and Recognition
At Dead Woman’s Pass (4,215m), you’re breathing air with 60% of sea-level oxygen. For clinical guidance, the CDC Yellow Book chapter on high-altitude travel is the authoritative reference.
Common symptoms:
- Headache
- Nausea or loss of appetite
- Fatigue beyond normal tiredness
- Shortness of breath during light activity
- Difficulty sleeping
Prevention strategies:
- Arrive in Cusco 2-3 days early to acclimatize
- Stay hydrated (3+ liters daily)
- Avoid alcohol before and during the trek
- Ascend slowly and rest frequently
- Eat light, carbohydrate-rich meals
- Consider Diamox (prescription, discuss with your doctor)
Natural remedies that help: Coca tea (widely available, effective), ginger for nausea, slow breathing techniques.
Warning signs requiring descent:
- Severe headache not responding to medication
- Persistent vomiting
- Loss of coordination or confusion
- Chest tightness or difficulty breathing at rest
Our guides carry supplemental oxygen and are trained to recognize altitude sickness progression. The trail has evacuation points for medical emergencies.
Acclimatization Protocol
We require trekkers to arrive in Cusco at least 48 hours before their trek start date. A workable plan for those two days:
Day 1 in Cusco: rest. Walk gently around the plaza, drink coca tea and stay hydrated. Cusco sits at 3,400 m, so sleep is often broken the first night.
Day 2: Light exploration. Consider a half-day Sacred Valley tour, which takes you to lower elevations (2,800m) while maintaining activity. This helps acclimatization more than sitting still.
Day 3: Trek begins. Your body has begun adapting.
Consider extending to 3-4 pre-trek days if you live at sea level, are over 50, or have any respiratory conditions.
Trail Safety
- Guides accompany all groups at all times
- First aid certified staff
- Satellite phone or radio for emergencies
- Daily weather monitoring and route adjustment if needed
- Porter welfare checks to maintain support team health
Is the Inca Trail dangerous?
Not with proper preparation and a responsible operator. The main risks, altitude sickness and injury from falls, are manageable through acclimatization and an appropriate pace.
Travel Insurance: What Coverage to Look For
Treat travel insurance as non-optional for the Inca Trail. Look for three things in your policy: emergency medical evacuation up to at least $100,000 (helicopter or ground transport from 4,000m+ terrain is expensive), altitude-related illness coverage: some standard policies exclude activities above 4,000m, so confirm Dead Woman’s Pass is included, and trip cancellation and interruption coverage since permits are non-refundable. Read the activity exclusion list carefully before you buy.

What the Inca Trail Costs
In our comparison of current-season rates at 15+ licensed operators, a 4-day group trek costs $600–900 at the budget end, $900–1,300 mid-range and $1,900–4,000 for luxury or private departures, with the permit and Machu Picchu entry included. Our classic 4-day Inca Trail is $749 per person ($699 for students) and ends at Machu Picchu. The train and bus back to Cusco are a $70 add-on with the Expedition train ($51 via Hidroelectrica), and the Cusco round trip with the return included is $819. The 2-day Inca Trail starts at $595. Tips for the crew run $40–80 per trekker and are not in any of these prices; rentals and the other extras are in our Inca Trail cost breakdown.
How to Choose an Operator
Independent hiking is banned, so the operator decides most of your trek. Three checks narrow the field.
- Licence: the agency needs a tourism contract with SERNANP, and your guide must be on SERNANP’s official list.
- Group size: the legal maximum is 16 trekkers. Ask for the actual average and the guide-to-trekker ratio (ours are 8 and one guide for every six).
- What the price includes: confirm the permit, the Machu Picchu ticket, the return to Cusco and sleeping-bag rental are in the quote. A cheaper quote that leaves them out is not comparable.
No Inca Trail Permits? Alternative Treks
If Inca Trail permits are sold out for your dates, these three treks need none. See our expert trekking tips before you decide.
Salkantay Trek (5 Days)
The Salkantay Trek is the most popular Inca Trail alternative.
Distance: 74 km (46 miles)
Duration: 5 days, 4 nights
Highest point: 4,630m (15,190 ft), higher than Dead Woman’s Pass
Permits: Not required (book flexibility)
Daily trekkers: ~50 (much less crowded)
Highlights:
- Salkantay peak (6,271m) dominating views
- Humantay Lake, a glacial lake
- Diverse ecosystems from alpine to jungle
- Hot springs at Santa Teresa
- Arrival at Machu Picchu via train from Hidroelectrica
Trade-offs: You won’t walk through the Sun Gate. The final approach to Machu Picchu is by train or via Hidroelectrica, not on foot.
Best for: Trekkers who prioritize natural scenery over archaeological sites, those with last-minute plans, budget-conscious travelers.
Read the full Salkantay Trek guide
Lares Trek (4 Days)
The Lares Trek emphasizes cultural immersion over ancient ruins.
What makes it different: The route passes through remote Quechua communities, where you meet weavers, farmers and families living traditional highland lives. There are hot springs along the way.
Best for: Travelers interested in living Andean culture, photographers seeking authentic human connection, those who’ve done the Inca Trail previously.
Explore the Lares Valley Trek to Machu Picchu (7 days)
Deciding between the two? Read Lares Trek vs Inca Trail, compared side by side: altitude, permits, crowds and what each price includes.
Choquequirao Trek (4-5 Days)
Choquequirao is the demanding, quiet option. The 4-5 day route goes there and back and does not reach Machu Picchu; continuing on foot to Machu Picchu takes 8-9 days.
What makes it different: Choquequirao is often called Machu Picchu’s “sister city” and is reached by only ~30 visitors a day. The trek is far more demanding, with steep descents and climbs into a remote canyon. Less than 30% of the site has been excavated.
Best for: Fit trekkers seeking adventure, those who’ve done other Peru treks, archaeology enthusiasts willing to work for undiscovered ruins.
