Peru
Cotahuasi Canyon
Deeper than Colca, deeper than the Grand Canyon, and barely a soul to share it with.
The trail drops and drops, the canyon walls rising until the sky narrows to a strip of blue high above. Down here, the Cotahuasi River roars through a gorge so deep the sound arrives before the sight of it. At the rim, the air is thin and the silence vast — Cotahuasi Canyon in Peru is a place measured in vertical kilometres, not horizontal ones.
Cotahuasi Canyon, located in the Arequipa Region, is one of the deepest canyons on Earth — reaching approximately 3,535 metres from rim to river at its most extreme point. It exceeds both Colca Canyon and the Grand Canyon in sheer depth. Yet it receives a tiny fraction of the visitors, partly because the overland journey from Arequipa takes around 12 hours on a winding mountain road. The canyon shelters pre-Inca agricultural terraces, hot springs at Luicho, and the Sipia waterfall plunging 150 metres into the gorge. Multi-day treks pass through remote villages like Quechualla and Chaupo, where families have farmed terraces for centuries. The remoteness is the point: Cotahuasi is Peru's wilderness canyon, untamed and largely unvisited.
Solo
The multi-day trek through the canyon is one of Peru's most rewarding solitary challenges — days of trail without another tourist, nights in village guesthouses, and a sense of earned isolation that more accessible treks cannot match.
Friends
Tackling the canyon as a group transforms the logistical challenge — the long drive, the river crossings, the altitude — into shared adventure. The hot springs at Luicho and camp-fire suppers become the reward for collective effort.
- The canyon reaches approximately 3,535 metres in depth — among the deepest on Earth and measurably deeper than Colca Canyon.
- The Cotahuasi River at the canyon base has Class V whitewater sections — among the most technically demanding in South America.
- Fewer than 5,000 tourists visit per year — compared to hundreds of thousands at Colca — making solitude the standard experience.
- The villages inside the canyon, including Quechualla, are accessible only by a narrow path carved into the canyon wall — no road descends to them.
