🏔️ 2. Who is Apu Salkantay? The Spirit of the Mountain
To understand the trek, you must first understand Salkantay.
🌟 Apu Salkantay: Sacred Mountain
In the Andean worldview, an Apu is a protective mountain, a powerful spirit that watches over communities, regulates the climate, and governs crops, water, and life.
Apu Salkantay is one of the most important mountains in southern Peru.
📖 Etymology of the name
In Quechua:
- Sallqa = wild, untamed
- Antay = to produce avalanches or snow waves
Therefore, Salkantay means:
👉 The Wild Lord who produces avalanches
👉 Untamed mountain
👉 Sacred mountain that commands respect
This name reflects the immense, cold, and revered nature of the Apu.
📜 3. History of the Salkantay Trek: The Ancestral Path

- A ceremonial territory to honor the Apu (mountain spirits)
🔶 Relationship with Machu Picchu
According to archaeological studies, the Salkantay was part of a spiritual circuit that connected sacred mountains with Machu Picchu.
