Discover more about Cerro Guanaco

Cerro Guanaco, nestled within the stunning Tierra del Fuego National Park, presents a demanding but ultimately gratifying hiking experience. This challenging trail, ascending nearly 1,000 meters, is considered one of the park's premier trekking routes, rewarding hikers with unparalleled panoramic vistas. The journey begins near Lake Acigami (formerly Roca Lake), from where a clearly marked path guides adventurers. The initial section meanders through a dense Lenga forest, with the tree roots creating a natural staircase for the ascent. Be prepared for potentially muddy conditions within the forest, though an alternate path exists to bypass the worst of it. Emerging from the forest, the landscape transforms into a more exposed, rocky terrain. The final stretch, approximately 2.5 kilometers, is the most arduous, often buffeted by strong winds and potentially covered in snow, even during summer. However, reaching the summit unveils breathtaking views encompassing Ushuaia, the Beagle Channel, Navarino Island, and the vast expanse of Tierra del Fuego National Park. Before embarking on this trek, it's essential to register at the Alakush Visitor Center and to start the hike before 12 PM. This is to ensure hikers have ample time to complete the trail before nightfall. Check weather conditions, as the final ascent can be hazardous in strong winds or after heavy rain.
