Serene glacier-rimmed bays and native Fuegian forest comprise this 1500-sq-km national park. Located in the Cordillera Darwin, it is a strategic wildlife corridor between Argentina's Parque Nacional Tierra del Fuego and Chile's Parque Nacional Alberto de Agostini.
Partially a one-time estancia comprising 400 sq km, it has been in the process of removing livestock and rehabilitating trails. The Vicuña–Yendegaia road through the park is due to be finished in 2021. Trails and visitor infrastructure are in the works.
Unfortunately, access is difficult and expensive. Visitors should plan to camp and be completely self-supported. There are no provisions available here and there is no on-site phone contact.
