Fagnano, the lake that moves
Fagnano—also shared with Chile and called Khami in native language—is the largest lake in Tierra del Fuego. It is surrounded by mountain ranges and lengas forests, and it belongs to Corazón de la Isla Provincial Reserve, in the department of Tolhuin. The lake shores run along some parts of the road when you enter Ushuaia overland and you can also go on full-day tours that take you to the shore. From Ushuaia, you can book excursions to visit the lake, including rides on 4WD vehicles, cycling, birdwatching and sport fishing.
In addition to its natural beauty, there is something special in its geological features: at the bottom of the lake lies the Fagnano-Magallanes fault, where South American and Scotia tectonic plates meet. This fracture in the Earth’s crust causes a 5mm movement of the lake in the east-west direction.
