The Salkantay Trek is harder than the Classic Inca Trail, mainly because of one number: 4,600 meters (15,090 feet) at Salkantay Pass on day two, about 400 meters higher than the Inca Trail's highest point at Dead Woman's Pass. It is not a technical climb and you do not need mountaineering experience, but it does demand real cardiovascular fitness and several hours of daily hiking across four to five days, most of it at altitudes where the air genuinely gets thin.
This guide to Salkantay Trek difficulty covers exactly how hard each day is, the training that actually prepares you for it, and a Salkantay Trek vs Inca Trail comparison if you're still deciding between the two.
How Difficult Is the Salkantay Trek, Really?
Rate it moderate to strenuous. You'll trek 6 to 9 hours a day across four days of genuinely varied terrain: steep ascents out of Mollepata, a long descent after the pass that's harder on the knees than the climb itself, and muddy, steep sections dropping into the cloud forest on the final approach to Aguas Calientes. It is not impossible for a reasonably fit beginner, but it rewards preparation more than the Inca Trail does, since there's no permit system capping daily hikers and no ranger checkpoints pacing the group, you set more of your own rhythm, which means your own fitness matters more.
Mules carry the heavy gear on most departures, so you're hiking with a day pack, not your full duffel. If you're already a seasoned trekker comfortable at altitude, hiring a mule and muleteer for your own gear on top of that is worth considering for the steepest sections.
Distance and Daily Mileage
The full Salkantay Trek covers roughly 74 km (46 miles) over five days:
- Day 1: Mollepata to Soraypampa, about 15 km (9.3 miles), a moderate uphill climb with a steeper, more cautious descent.
- Day 2: Soraypampa to Collpapampa, about 22 km (13.7 miles), the hardest day, including the full climb and descent of Salkantay Pass.
- Day 3: Collpapampa to La Playa, about 16 km (9.9 miles), dropping into semi-tropical cloud forest and coffee country around Lucmabamba.
- Day 4: La Playa to Aguas Calientes, about 19 km (11.8 miles), flatter on paper but takes 8 to 9 hours and includes the stop at Llactapata for your first distant view of Machu Picchu.
- Day 5: A short 4 km (2.5 mile) morning to explore Machu Picchu itself before heading back to Cusco.
The Altitude Day: Salkantay Pass at 4,600 Meters
Day two is the day that defines this trek's difficulty. Salkantay Trek altitude peaks at the pass itself, 4,600 meters (15,090 feet), the highest point most travelers reach on any Cusco-region trek, and altitude sickness risk is real at that elevation even for experienced hikers. The CDC's Yellow Book guidance on high-elevation travel recommends spending time acclimatizing at intermediate elevation before ascending further, which is exactly why we recommend 2 to 3 days in Cusco (3,400m) before starting the trek, not just for comfort, but because it measurably reduces your risk on day two.
Coca tea, a slow steady pace, and staying well hydrated all help on the day itself, but acclimatization time beforehand matters more than anything you can do on the trail.
How to Train for the Salkantay Trek
Start training at least six weeks out, or up to four months if you're not currently active. Your training should cover three things:
- Aerobic endurance: Running, cycling, or brisk hiking several times a week to build the cardiovascular base that altitude will otherwise punish.
- Strength conditioning: Squats, lunges, and step-ups to prepare your legs for the day two descent, which is harder on most people than the climb up.
- Load-bearing practice: Hike with a loaded day pack at least a few times before you travel, so day one on the actual trail isn't the first time your shoulders and hips feel that weight.
Build up gradually, from 1-hour hikes early in your training block to something closer to 10 km by the final weeks. If you're starting from a lower fitness level, talk to your doctor before ramping up, especially if you have any cardiovascular or respiratory history that altitude could complicate.
Salkantay vs. Inca Trail: Which Is Harder?
Salkantay is the physically harder trek, mainly because of that 4,600m pass, roughly 400m higher than anything on the Classic Inca Trail. The Inca Trail counters with tougher terrain underfoot, endless uneven stone steps that wear on your knees in a different way than Salkantay's dirt trails. For the full side-by-side on crowds, scenery, and permits, our Inca Trail vs. Salkantay Trek comparison guide breaks it down. If you want the complete day-by-day logistics beyond difficulty, our Salkantay Trek Itinerary covers that in full.
Frequently Asked Questions
How hard is the Salkantay Trek compared to a normal hike?
Significantly harder than a typical day hike. You're covering up to 22 km in a single day at altitudes above 4,000 meters, which is a real physical undertaking even for people who consider themselves reasonably fit at sea level.
Do I need trekking experience to do the Salkantay Trek?
No technical climbing experience is needed, but prior multi-day hiking experience helps, especially with pacing yourself on long descents.
What is the highest point on the Salkantay Trek?
Salkantay Pass, at 4,600 meters (15,090 feet), reached on day two.
Is the Salkantay Trek harder than the Inca Trail?
Yes, primarily due to the higher altitude at Salkantay Pass. See our full comparison guide for the complete breakdown.
How many days should I acclimatize in Cusco before the Salkantay Trek?
At least 2 to 3 days at Cusco's elevation (3,400m) before starting, per CDC high-altitude travel guidance, to meaningfully lower your risk of altitude sickness on day two.
Ready to Take On Salkantay?
Five days, real mountains, and a team that knows exactly how to prepare you for day two.
