Carretera Austral
7Villa Cerro Castillo to Puerto Río Tranquilo
Ruta 7 leaves the rock spires of Cerro Castillo, drops into the Río Ibáñez valley and runs the shore of Lago General Carrera, South America’s second-largest freshwater lake, to the Marble Caves at Puerto Río Tranquilo. Mostly gravel, punishingly corrugated, properly remote.
Departing Villa Cerro Castillo beneath the park’s rock spires, Ruta 7 drops into the Río Ibáñez valley and crosses into remote Patagonia. It threads through Valle Murta and hugs the shore of Lago General Carrera, the second-largest freshwater lake in South America, before arriving at Puerto Río Tranquilo and its Marble Caves. Largely gravel with punishing corrugation; high clearance recommended.
