Montes Martial with summit attack to Cerro Rebert, 3 days


  • Explore a wild area on the edge of the earth - the legendary Tierra del Fuego
  • Experience the unique flora and fauna of a unique subartic ecosystem
  • Option to trek supported (with porters) or autonomous, based on preference


Explore the incredible wilderness of Tierra del Fuego National Park during this 3 day trek through some of the most incredible landscapes of the Earth’s extreme Southern latitudes!

Tierra del Fuego National Park, located at the southern tip of the South American continent, is one of the most remote areas on the planet. Those who venture through its subpolar forests, guanuco trails, and glacial lakes are rewarded with an awe inspiring experience in a wilderness that is still little explored. The unique landscape is especially spectacular as it combines the landscape of the High Andes altiplano with the oceanfront cliffs and marine life of the nearby sea.

During this 3 day adventure, we will complete the point-to-point Montes Martial trek through some of the most stunning areas of the national park.  A transfer from Ushuaia takes us to the trailhead. From there, we will cover 30.4 km on foot as we trek to such highlights as the Laguna del Caminante, Andorra Valley, and Paso de Oveja (“Sheep’s Pass” in Spanish).  As an added bonus, we will complete a relatively easy summit of Mount Rebert (also called Mt. Falso Tonelli), from which we will enjoy unbelievable panoramic vistas from the Beagle Channel to the surrounding cordillera.  The total elevation gain of the trek is 1,775 m, with an elevation loss is -1,904 m.  A day-by-day outline is included below.

The price quoted is for a supported trek and includes the use of porters to carry group camping equipment and food.  The price also includes all transfers during the trip to and from Ushuaia, meals and snacks, guiding services, and group equipment.  You will need to bring personal equipment and a sleeping bag for the nights spent camping in the wilderness.  Please note that porters will not be provided to carry personal equipment.  Upon request and for a reduced price, I can also offer this trek as an autonomous adventure, in which we will have to carry our own camping equipment and food.
