Tierra del Fuego National Park
Founded in 1960, the Parque Nacional Tierra del Fuego is located about twelve kilometers west of Ushuaia and is Argentina's only national park uniting mountains, forest, and coastline. It protects the last section of the Andes and the subantarctic forest of Lengas and Ñires, along with extensive peat bogs.The road in the park is the final stretch of Ruta Nacional 3 and ends at Bahía Lapataia with the famous 'Fin de RN3' sign. At Bahía Ensenada, you'll find the southernmost post office where you can get your passport stamped; from there, the Senda Costera leads as a moderately difficult coastal path along the Beagle Channel. Further trails lead to Lago Acigami and up Cerro Guanaco. An entrance fee is charged for the park; the ride on the Tren del Fin del Mundo costs extra.
