Tierra del Fuego National Park is a protected area located in the southwestern part of Isla Grande de Tierra del Fuego. It is Argentina's first coastal national park, extending from the Beagle Channel in the south to the Andes in the north. The park encompasses a diverse landscape of mountains, forests, lakes, and peat bogs. It protects a representative portion of the Subantarctic forest, primarily consisting of lenga, coihue, and ñire trees. The area is notable for its southernmost extent of the Andes range and features glacial valleys and moraines. The park provides a habitat for native fauna including the Andean fox, guanaco, and various bird species such as the Magellanic woodpecker and austral parakeet. Human history in the region includes the presence of the indigenous Yaghan people, whose presence is documented archaeologically. The park offers various trails for visitors and is traversed by the southern terminus of the Pan-American Highway. The climate is characterized as subpolar oceanic, with cool temperatures, strong winds, and high precipitation throughout the year.
