Campamento Poincenot is a backcountry campground inside Los Glaciares National Park, situated roughly 10 kilometers from El Chaltén along the Río de la Cascada corridor, beneath the granite towers of the Fitz Roy Massif.

It serves as the traditional overnight base for trekkers and climbers heading to Laguna de los Tres and the surrounding high-alpine viewpoints. The site sits in a forested valley of lenga beech, which offers some shelter from Patagonia's strong winds.

Facilities are basic — latrines are provided, but there are no showers or supplies. Drinking water is available from a nearby stream. Fires are prohibited, and campers must pack out all waste.

Access is on foot only, approximately a four-hour hike from El Chaltén. From camp, the climb to Laguna de los Tres is about 2. 5 kilometers with roughly 400 meters of elevation gain — a one- to one-and-a-half-hour ascent.

Staying here gives trekkers a significant head start for pre-dawn departures to catch sunrise over Mount Fitz Roy. Reservations and camping fees are managed through the national park system.
