Peru
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 β 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 β 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 β 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 β the long drive, the river crossings, the altitude β into shared adventure. The hot springs at Luicho and camp-fire suppers become the reward for collective effort.
