The Cotahuasi River originates in the Peruvian Andes at an elevation of approximately 4,750 meters near the Huayzacocha lagoon. Over millions of years, its waters have carved out the Cotahuasi Canyon, which reaches a maximum depth of 3,535 meters, making it one of the deepest canyons on the planet. The river flows through the Arequipa region and eventually joins the Ocoña River system before emptying into the Pacific Ocean. Its course is marked by dramatic elevation changes, creating numerous rapids and the impressive Sipia Falls, which drop 150 meters. The surrounding valley is home to ancient Inca terraces and diverse microclimates that support a wide range of flora and fauna. Due to its remote location, the river basin has remained relatively untouched by modern industrial development, preserving its natural state and traditional Andean heritage.

📋 Practical info
Getting there
Reaching this remote destination typically involves a lengthy bus or private vehicle ride from the city of Arequipa, navigating a scenic but challenging high-altitude road to the village of Cotahuasi.
Best season
The dry season, falling between May and November, is highly recommended for visiting, as the roads are generally safer to traverse and the canyon trails are free from the heavy summer rains.
Terrain & paths
The landscape provides extreme variations in altitude, presenting steep, rugged descents into the deep canyon alongside terraced agricultural paths that have been used by local communities for centuries.
What to bring
Thorough preparation is necessary, requiring sturdy trekking boots, layers for fluctuating temperatures, a reliable headlamp, comprehensive sun protection, and a well-stocked first aid kit for remote travel.
Parking
Visitors driving themselves typically park their vehicles in the main plaza of Cotahuasi village or at established accommodations, using these locations as secure basecamps for further canyon exploration.
Safety
The sheer remoteness means medical help is far away; visitors should acclimatize properly, stay on established paths to avoid dangerous drops, and always carry sufficient emergency water supplies.
Time needed
Due to the arduous journey just to reach the area, a minimum of three to four days is highly recommended to fully appreciate the region, complete significant hikes, and visit the striking waterfalls.
