Campamento Poincenot is a backcountry campground situated along Río Blanco, roughly 8–10 km from El Chaltén in Los Glaciares National Park.

It serves as the primary overnight stop for hikers tackling the classic Laguna de Los Tres route and offers a well-known vantage point for photographing Mount Fitz Roy at sunrise. The site has pit toilets and river access nearby.

Two trails reach the campground: the more popular route departs from Avenida San Martín in El Chaltén, passing the Laguna Capri viewpoint before arriving in approximately three to four hours; an alternative approach follows Río Blanco from Hostería El Pilar to the north.

From camp, a steep 1 km climb gaining roughly 400 meters leads to the cobalt-blue waters of Laguna de Los Tres. The location also makes a good base for exploring Laguna Madre, Laguna Hija, and trails toward Laguna Torre.

Open fires are prohibited throughout the park.
