Salkantay Pass

If you’re planning the Salkantay Trek to Machu Picchu, there’s one place you’ll hear about again and again: Salkantay Pass. This high-altitude mountain pass also known locally as Abra Salkantay is the most challenging and breathtaking section of the entire route. Standing at an impressive 4,630 meters (15,190 ft) above sea level, it is the point where trekkers push their limits, witness the raw power of the Andes, and experience what many describe as the highlight of their entire Machu Picchu journey.

This in-depth guide walks you through everything you need to know about Salkantay Pass: weather, altitude, trail conditions, difficulty, safety tips, acclimatization, what to bring, when to go, and what to expect on summit day.

What Is the Salkantay Pass?

Salkantay Pass is the highest point of the classic Salkantay Trek, sitting between two majestic Andean peaks Salkantay (6,271 m) and Humantay (5,473 m). The pass connects the high-altitude alpine zone with the lush cloud forest that leads toward Machu Picchu.

Crossing this pass feels like entering another world:

• The air becomes thinner and colder.

• The landscape turns rocky, snowy, and dramatic.

• The silence of the mountains surrounds you.

• You feel the ancient Andean energy that locals associate with Apu Salkantay, one of the most sacred mountains in Inca mythology.

For many travelers, reaching Salkantay Pass is a personal challenge and a deeply spiritual experience.

Where is Salkantay Pass Located?

Salkantay Pass is located in the Vilcabamba Mountain Range in the Cusco region of Peru, southwest of Machu Picchu. The pass lies along the traditional Salkantay Trail, approximately 2 – 3 hours uphill from the Salkantay Pampa campsite or the newer Soraypampa Sky Camp area.

Its coordinates fall within the Salkantay Route, which is officially part of the alternative network of trails leading to Machu Picchu.
