Completely surrounded by the Guanaco and Piramides Mountain Ranges, both sub ranges of the Andes, Lago Roca is a stunning emerald-green lake protected by Argentina’s Tierra Del Fuego National Park.
The Lago Roca hostel and campground is the easiest starting point to explore this section of the national park. Fishing is popular on the lake, while several trails lead around the lake and into the surrounding mountains. The Cerro Guanaco Trail is a steep climb to a mountain summit. The views from the top are massive, overlooking Lago Roca, the Beagle Channel, and across the border into Chile.
It’s a lake with an identity crisis, too, as Lago Roca – named for former Argentinean president Julio Argentino Roca - is just the most recognized of its three names. The western most portion of the Lake crosses the international border into Chile, where the lake is known as Lago Errazuriz, after Chile’s former President Federico Errázuriz Echaurren. Roca and Errazuriz share a history in Patagonia, as both were recognized for the Abrazo del Estrecho (the hug of the Strait of Magallanes) when they met in Punta Arenas to find a friendly solution to conflicting Patagonian land claims.
Prior to being renamed Lago Roca and Errazuriz (depending on which side of the border you visit), the lake was known as Lago Acigami, the yagan native name.
Lago Roca is located in Tierra Del Fuego National Park, just over 12 km from Ushuaia. Throughout the summer, hourly buses make the round trip between the Park Administration office (Maipú and 25 de Mayo, Ushuaia) and Lago Roca.
