Rock Climbing in Cochamo Valley
The Yosemite of South America: a roadless valley of 1,000-meter granite walls in Los Lagos, reached on foot with pack horses and capped by a reservation system.
Why here
Cochamo holds the biggest granite walls on the continent, up to 1,000 meters, on more than 200 routes from 5.9 multi-pitch to A5 aid, and the valley is roadless: everyone walks in four to five hours behind pack horses, and camping is reservation-capped, so the place cannot crowd. It has been called the Yosemite of South America for the granite, but the wilderness character is the real difference: no shuttle buses, no rangers' loop road, just rainforest, walls, and whatever you carried in. Guided big-wall courses and classic objectives like Cerro Trinidad run all season for climbers ready to step up from sport routes.
Best months
December through March is the season, January and February the busiest and driest. Valley camping reservations are required and cap capacity; multi-day weather windows matter for the big lines, so build slack days into the trip.
Getting there & around
Fly to Puerto Montt (PMC), about 2.5 hours to Cochamo town, then hike in. Book valley camping and guides one to three months ahead for January-February.
