Salkantay trek difficulty: how hard is this alternative to the Inca Trail

Trekkers weighing the Salkantay trek against the Inca Trail usually ask the same question first: which one is harder. The honest answer is Salkantay, at least on paper, since it climbs higher and covers more total distance across its five days.

That said, difficulty here comes with more variety than a single hard day. Cloud forest, glacial passes and coffee valleys break up the effort in ways that keep the trek from feeling like a grind.

Altitude at Salkantay Pass

The trek’s defining challenge is Salkantay Pass itself, sitting at roughly 15,200 feet, nearly 1,400 feet higher than Dead Woman’s Pass on the classic Inca Trail. Thinner air at that height means slower progress and a higher chance of altitude-related fatigue, even for trekkers in strong physical shape.

Day two typically covers this pass, with an early morning climb through cold, thin air before descending into warmer cloud forest by afternoon. That descent brings real relief, both in oxygen levels and temperature, after a demanding morning.

Acclimatizing in Cusco for two to three days before starting reduces symptoms considerably, since the trailhead itself already sits above 9,000 feet before any climbing begins.

Terrain and daily distances

Five days cover roughly 46 miles total, longer than the Inca Trail’s 26, though daily distances vary considerably. The middle days through cloud forest and coffee-growing valleys offer gentler grades than the mountain pass crossing, giving trekkers a physical and mental break before the trail steepens again near Machu Picchu.

Trail conditions range from well-maintained dirt paths to rockier, less predictable sections near the higher elevations. Trekking poles help considerably on the steeper descents, where loose rock and uneven footing test tired legs more than the climbs themselves.

Weather conditions along the route

Temperature swings define this trek as much as altitude does. Near Salkantay Pass, nighttime temperatures can drop below freezing, while the lower cloud forest sections later in the trek feel humid and warm, often exceeding 75°F.

Rain is more common on this route than on the Inca Trail, particularly in the cloud forest sections, so packing genuinely waterproof gear rather than just water-resistant layers makes a real difference in comfort.

Preparing for the Salkantay trek

Cardiovascular fitness matters most for the pass crossing, while general trekking stamina carries you through the longer overall distance. Training with a loaded daypack over hilly terrain for two to three months beforehand prepares most trekkers adequately.

At Yeska Tours, our guides pace every group carefully around Salkantay Pass specifically, since that single day determines how the rest of the trek feels for most hikers. We also build in the hot springs stop many itineraries include near the end, a welcome reward after five demanding days on the trail.

Salkantay asks more of trekkers than the Inca Trail in raw numbers, but the variety of terrain and lack of permit restrictions make it one of the most rewarding multi-day treks in the region for those willing to put in the training beforehand.

Comparing Salkantay to other treks near Cusco

Against the Inca Trail, Salkantay wins on scenery variety and loses on convenience, since no permit is required but the pass sits considerably higher and the total distance runs nearly twice as far. Against Choquequirao, Salkantay actually comes out easier overall, since it lacks the brutal canyon descent and climb that defines that route, even though Salkantay’s single highest point exceeds Choquequirao’s maximum altitude.

Rainbow Mountain and Humantay Lake, both single-day hikes, obviously involve far less cumulative effort, though Humantay in particular pairs naturally with the start of the Salkantay trek itself, since many itineraries route directly past the lake on day one.

Training tips specific to Salkantay

Interval hiking, alternating between steep uphill pushes and recovery sections, mimics the trek’s terrain better than steady-pace treadmill walking. Building up to multi-hour hikes with a loaded pack over the two to three months before departure conditions both your legs and your lungs for the sustained demands of day two specifically.

Practicing on any available elevation, stairs, hills or a stair-climbing machine if flat terrain is all that’s accessible, translates directly to performance on Salkantay Pass. Trekkers who arrive undertrained tend to struggle most in the final push before the pass, precisely the section where turning back becomes hardest and pressing on becomes most necessary.
