The Carretera Austral (CH-7) is the name given to Chile's Route 7. The highway runs about 1,240 kilometers (770 mi) from Puerto Montt to Villa O'Higgins through rural Patagonia.
Carretera Austral provides road access to Chile's Aysén del General Carlos Ibáñez del Campo Region and southern part of Los Lagos Region. These areas are sparsely populated and despite its length, Carretera Austral provides access to only about 100,000 people. South of the highway's start in Puerto Montt, Coyhaique (population 44,850) is the largest city along it.
