Mount Tarn is a small mountain located on the southernmost part of the Strait of Magellan, in Brunswick Peninsula, about 70 km south of Punta Arenas, Chile. It is in the southern extreme of continental Chile very close to Cape Froward, surrounded by historic places such as Fort Bulnes and Puerto del Hambre (Port Famine).
From the summit it is possible to see the Strait of Magellan, Dawson and Tierra del Fuego islands, and many other smaller ones; the Darwin Mountain Range, Mount Sarmiento, and most of the Brunswick Peninsula.
