🇨🇱 Chile · Southern Chile
Cochamó is a small village and, above all, a valley of granite walls in southern Chile that has earned the nickname 'the Chilean Yosemite'. Set on the Reloncaví estuary, in the Los Lagos Region, it is one of the country's most coveted destinations for trekking, climbing and wild nature, famous for its rock faces hundreds of meters high, its alerce forests and its frontier atmosphere.
The village of Cochamó, beside the inland sea of the estuary, is the gateway. From there, or from the El Arco sector, begins the historic trail into La Junta valley, the heart of the destination: a full day's walk along an old muleteers' track, often deep in mud, that winds through the forest to a valley ringed by granite domes and walls that draw climbers from all over the world.
Cochamó is nature in the raw and it demands preparation: hard trails, wet weather, no phone signal or services in the valley, and a booking system to control the numbers coming in. In return, it offers landscapes of brutal beauty. This guide covers how to organize the trek, what to bring, where to sleep and how to look after this fragile and singular place.
The Cochamó valley was inhabited and traveled by Indigenous peoples and, from the 19th century, by settlers and muleteers who cut an ox track to drive cattle into Argentina over the mountains. That old log trail (the 'muleteers' road') is today the access route into the valley. In the late 20th and early 21st centuries, Cochamó was 'discovered' by the international climbing community, which revealed its granite walls and turned it into a world icon of trekking and rock climbing.

Origins, formation and what the sources say.
The logs that thousands of trekkers tread on their way to La Junta valley have been lying there for more than a century. They were not laid for tourism: they were hewn by hand, one by one, by the muleteers who at the end of the 19th century cut a track for driving oxen and cattle across the mountains into Argentina. Every plank polished by mud and hooves is a fragment of the Cochamó that existed before climbing, when this corner of the Reloncaví estuary was not 'the Chilean Yosemite' but merely a path for smuggling and the cattle trade in one of the most isolated corners of southern Chile.
The area, around the Reloncaví estuary —the northernmost fjord in Chilean Patagonia— was traveled by Indigenous peoples and, from the 19th century, settled by families who lived off livestock, fishing and subsistence farming in surroundings of wet rainforest, mountains and inland sea. Trade with the Argentine side, over the mountain passes, was one of the few economic outlets, and so the muleteers' track became a vital work: a log path that let herds be driven through the mud, the fast rivers and the impenetrable forest.
That same track, its logs worn by generations of footsteps, is today the access route into La Junta valley, and walking it means literally following in the footsteps of those old muleteers. The culture of the muleteer and the estuary farmer marked Cochamó's identity forever: a village of rural traditions, bound to the horse, to livestock and to the inland sea. That inheritance lives on in the local families, many of whom now take part in tourism as guides, muleteers and hosts of the valley, carrying luggage on horseback along the very trail their great-grandparents cut with axes.
The Cochamó valley underwent a transformation at the end of the 20th century and the start of the 21st, when the international climbing community noticed its extraordinary granite walls and domes. The faces hundreds of meters high, of excellent rock, began drawing climbers from the United States, Europe and elsewhere, who opened routes and spread images of the valley, comparing it to the famous Yosemite. That is how the nickname 'the Chilean Yosemite' was born.
Its fame grew fast and, with it, came trekking and climbing tourism. La Junta valley became a coveted destination, which brought a dilemma: how to open Cochamó to the world without destroying its fragility. The rise in visitors put pressure on the trails, the campsites and the fragile ecosystems of native forest and alerce.
The answer came from the local community itself and from conservation organizations, which drove forward a booking and regulated entry system, with limited places, to control the numbers and protect the valley. Cochamó has thus become an emblematic case of responsible nature tourism in Chile: a destination of wild beauty that is actively cared for, where visitors must plan, book and commit to low-impact practices so that the place remains what it is.
The geography that today astonishes climbers and trekkers in Cochamó is the product of processes told in millions of years. The valley's great granite domes and walls belong to the so-called North Patagonian Batholith, an enormous body of plutonic rock formed when masses of magma crystallized slowly deep in the crust, tens of millions of years ago, and which the uplift of the Andes gradually exposed at the surface.
The ice then went to work on that rock. During the Quaternary glaciations, enormous glaciers carved and polished the valley, leaving the vertical walls, the rounded domes and the broad U-shaped valley floors that characterize Cochamó and that so recall Yosemite. The polished rock slides down which the water now runs are direct evidence of that glacial action.
On this relief grew one of the best-preserved temperate rainforests in southern Chile. The valley shelters evergreen Valdivian forest and, above all, specimens and stands of alerce (Fitzroya cupressoides), a thousand-year-old conifer —among the longest-lived on the planet, capable of exceeding three thousand years— now protected as a Natural Monument after its historic overexploitation. Mosses, ferns, coigües, lengas and wildlife that includes the pudú, the monito del monte and birds such as the Magellanic woodpecker round out a fragile ecosystem of the highest value, an essential part of what makes Cochamó unique.
Cochamó's 'discovery' by the world brought fame, but also concrete threats. Over recent decades the valley has been in the sights of projects that put its pristine character at risk: hydroelectric schemes to dam the rivers of the Puelo and Manso basins, transmission lines that would cross the area, and even the possibility of opening a vehicle road as far as La Junta, which would have ended forever its status as a valley reachable only on foot or on horseback.
Against those threats a powerful defense movement arose, bringing together local residents, muleteers, climbers, environmental organizations and visitors from all over the world under the banner of keeping Cochamó free of dams and roads. That public pressure, combined with the place's growing tourist and symbolic value, helped halt or postpone several of those projects and establish the idea that the valley's greatest capital is precisely its untouched nature.
Out of that awareness came the management model that governs it today: a booking and entry system with limited places, run with the participation of the local community, which controls how many people enter the valley so as not to exceed its carrying capacity. Low-impact practices are promoted —carrying out all your rubbish, using the designated areas, looking after the water and the trails— and the aim is for tourism to benefit the families of Cochamó, many of them descendants of the old muleteers, now turned guides, campsite keepers and hosts. Cochamó has thus become a South American benchmark for community-based conservation, a place where visiting also means committing to protect it.
For much of the 20th century, the walls of Cochamó were a secret kept by the forest and the rain. Climbing's first serious look came from Chilean and foreign mountaineers who, from the 1980s and 1990s, began exploring the valley's great granite domes, such as the imposing Cerro Trinidad, whose vertical face hundreds of meters high became the emblem of the area. Over the years, climbers from the United States, Europe, Argentina and Chile itself opened dozens of multi-pitch routes on granite of exceptional quality, comparable to Yosemite or the Torres del Paine.
The comparison with Yosemite is not just marketing: the geology (great domes and walls of glacier-polished granite), the climbing style (big wall and traditional, with multi-day routes) and even the aesthetics of a U-shaped valley ringed by forest justify the nickname 'the Chilean Yosemite'. The difference is that Cochamó has no roads, no lifts and no crowds: to climb here you have to walk for hours through mud, haul your gear on your back or by horse, and accept that the weather is in charge. That mix of difficult access and world-class rock is precisely what turned Cochamó into a place of pilgrimage for climbers from all over the world, especially in the good-weather window from December to March.
As photos of the valley circulated through magazines and social media, trekking joined climbing and Cochamó went from secret to phenomenon. It is now internationally recognized as one of South America's great rock climbing destinations and as a case study in how a remote place can become world-famous without losing —at least for now— its wild character. The story of Cochamó is, at bottom, the story of a valley that was a muleteers' track, then a sanctuary for climbers and, finally, a symbol of the fight to keep Patagonia intact.
