The largest area of protection in Chile, 35 000 square km. It's neighboured by Torres del Paine and Los Glaciares to its east, the two most popular national parks of Patagonia; and San Rafael National Park to its north. The main gateways to the park are Puerto Natales, Villa O'Higgins, and Tortel. It is one of the few homes left for the Patagonian Huemul. Marine otters and Andean condors are also frequently sighted here.
