Which national park covers the southern tip of the Andes in Argentine Tierra del Fuego?

Tierra del Fuego National Park covers the southern end of the Andes in Argentina’s Tierra del Fuego.

Established in 1960, the park lies on the Argentine side of Isla Grande de Tierra del Fuego, immediately west of Ushuaia. It protects a striking meeting point of mountains, glacial lakes, rivers, forests, and the Beagle Channel, combining Patagonian Forest and Altos Andes environments.

The park extends northward from the Beagle Channel toward Lago Fagnano and follows the Chilean border. Its landscapes were shaped by glaciation, leaving steep valleys, bays, beaches, and mountain passes. Popular destinations include Lapataia Bay, Lake Roca, Ensenada Bay, and the Coastal Path. National Route 3 ends inside the park at Lapataia Bay, giving it a symbolic place in South American travel.

The alternatives are major protected areas but belong elsewhere: Nahuel Huapi is farther north in Argentina, Los Glaciares is in Santa Cruz Province, and Laguna San Rafael is in Chile. The park’s name can sound merely regional, but this is the specific Argentine national park at the continent’s far southwestern edge.
