Peninsula Mitre – Argentina

Back to Locations

Mitre Peninsula is the westernmost part of Isla Grande de Tierra del Fuego, located in the southernmost part of the island. Is a mythical territory, extreme both from a geographic point of view and as a climate and accessibility. It is mainly mountainous, almost completely undeveloped and, in the lowlands, is covered by forests and peat bogs. The southern side overlooks the Beagle Canal with a long and wild rocky coast, which in the past was inhabited by the nomadic people of the Haush. The landscapes that this territory offers are among the most fascinating and original in the world.

The eastern part of the archipelago of the Tierra del Fuego, in Argentina, is known as the Mitre Peninsula, which extends over 12,000 square kilometers and represents an area of exceptional natural and cultural value, nowdays almost totally uninhabited, but once a land of the people of Fuegini: definitively extinct for many decades due to colonization, these extraordinary connoisseurs of this area have left numerous testimonies of incredible ability to adapt to the environment. The climate is subantartic wet, with rainfall throughout the year. The elevations that characterize this region, form the southern extremity of the Andes. The prevaling vegetation consists primarily of large extensions of australian beech trees such as Guindo (Nothofagus betuloides) and Lenga (Nothofagus pumilio), associated with canelo (Drimys winteri) e leña dura (Maitenus magellanica), in addition to a large development of ferns (Blechnum maguellanicum) and peat bogs (Sphagnum maguellanicum). The most important fauna consists of guanacos, sea lions and many bird species. Along the southern coast, stretched by implacable winds, giant waves and tides of 6 meters, in 2005, the southern caves on earth were discovered.

Accessibility by sea is complicated by lack of natural landings. We prefer to approach by helicopter, traveling about 150 km from the Estancia Rio Ewan, near the Lake Faganano (4 hours drive from Ushuaia). The Base Camp is a flat area of the inland, at Bahìa Aguirre.
