The Salkantay Trek is the most scenic alternative to the Inca Trail, leading trekkers through remote valleys and over a glacier-capped pass with views that are arguably more dramatic than anything on the classic route. Named after the 6,271-m Mt. Salkantay, this trek crosses the Andes from the high puna to lush cloud forest before connecting with the town of Aguas Calientes.

Route & Itinerary

Although there are variations, most itineraries cover about 74 km (46 mi) over five days. Day 1 begins at the trailhead near Soraypampa with a side hike to the turquoise Humantay Lake. Day 2 climbs steeply to Salkantay Pass at 4,630 m (15,190 ft), where glaciers loom overhead and winds can be fierce. The path then drops into the tropical Santa Teresa Valley. Day 3 follows the river through bamboo groves and banana plantations to the village of Lucmabamba. On Day 4 you ascend an Inca trail over Llactapata pass with a distant first view of Machu Picchu, then descend to the hydroelectric station to catch the train or continue on foot to Aguas Calientes for an overnight. Day 5 is spent exploring Machu Picchu.

Highlights

  • Climbing to Salkantay Pass, where icy peaks tower above you and stone cairns mark the trail.
  • A side trip to Humantay Lake, a glacial lagoon famed for its vivid turquoise colour.
  • Descending from high alpine tundra into humid cloud forest full of orchids, passionfruit vines and coffee plantations.
  • Optional detours to hot springs near Santa Teresa or zip-line adventures in the valley.

Difficulty & Preparation

Make no mistake—Salkantay is a challenging trek. Distances are longer than on the Inca Trail, and the ascent to 4,630 m can test even fit hikers. Nights at the high camps are cold, while afternoons in the jungle can be hot and humid. Acclimatize in Cusco and consider doing practice hikes to high elevation before tackling the pass.

Altitude & Weather Caution

Prepare for temperature swings—from freezing nights near the glacier to tropical heat in the valleys. Snowstorms are possible at the pass even during the dry season. Bring thermal layers, a sturdy rain jacket and gloves; trekking poles help with stability on steep descents.

Best Time to Trek

The best weather typically falls between April and September when the Andean highlands are dry and clear. December through March is the rainy season; heavy storms can close the pass and increase the risk of landslides. If you travel in shoulder months, bring waterproof gear and expect afternoon showers.

Planning Tips

No special permit is required for Salkantay, but booking a guided trek can ease logistics and provide support such as pack horses and cooks. Independent hikers should register at the trailhead and carry enough cash to pay for campsites and transport. Pack light and bring altitude medication, water purification tablets and insect repellent for the lower valleys.
