At the southernmost tip of South America, where the Andes meet the Beagle Channel, Tierra del Fuego National Park protects 63,000 hectares of subantarctic forest, glacial lakes, peat bogs, and rugged coastline that feel like the edge of the known world. Accessible from the frontier city of Ushuaia — the world’s southernmost city — the park is the final stop on Ruta Nacional 3, which begins over 3,000 kilometers north in Buenos Aires. Visitors can arrive via the End of the World Train, a narrow-gauge railway that follows the route once used by convicts from the old Ushuaia prison, winding through lenga and coihue forests and crossing the Rio Pipo before depositing passengers at the park entrance.

Trails wind through landscapes of extraordinary beauty and solitude. The Senda Costera follows the shoreline of the Beagle Channel past beaver dams and shell middens left by the indigenous Yamana people, while the Hito XXIV trail leads to a glacial lake marking the Chilean border. The Laguna Negra path traverses a moss-draped peat bog that feels primordially ancient. Andean condors soar overhead, Magellanic woodpeckers hammer at southern beech trunks, and the clear waters teem with trout. At Bahia Lapataia, a wooden sign marks the end of the Pan-American Highway — a symbolic and photogenic reminder that you have reached the literal end of the road.

Pro tip: Visit the post office at the park’s edge to get your passport stamped with the “End of the World” seal — it is a beloved souvenir. Wear waterproof layers even in summer, as Patagonian weather can shift from sunshine to horizontal rain in minutes, and the wind along the Beagle Channel is bracing.
