Monte Darwin is the highest peak of Tierra del Fuego. It rises on the Cordillera Darwin, a heavily glaciated range on the extreme southern shore of South America. Most of the high mountains of the cordillera rise within Chile, although the range stretches into Argentina, where, just across the border, Ushuaia is the world's most southerly city. Tourism is continually growing in Ushuaia, and several trails lead into the mountains from the city. Reaching the higher mountains, however, such as Monte Darwin and Monte Sarmiento, requires a boat.
