Carretera Austral is one of the most spectacular and challenging drives in the world. Running through the northwestern part of Chilean Patagonia, it’s a lifetime adventure for anybody.
The highway opened to traffic in 1988. Due to its unique location, and passing through remote areas (among the least inhabited in Chile), it is important when driving in these conditions to be prepared.
The winding road, formerly known as Carretera General Augusto Pinochet, is 1,240 km (770 miles) long, running north-south from Puerto Montt (in the Chilean Lakes District) to Villa O'Higgins (in the Aysén region), through the northern stretch of Chilean Patagonia. Along the whole road, it is possible to find an incredible variety of mountains, lakes, glaciers, and woods that make this land one of the world's wonders.
Most of the road (70%) is unpaved, ranging from quite good quality to absolutely horrible: be prepared for a bumpy drive. If you are driving, you will not need a 4WD but your car will be suffering. You will probably have to take a ferry or two to get in or travel along the road. The road conditions usually don't allow driving at too high speed. However, some people still drive quite fast (usually locals). Passing cars will create clouds of dust, which can be from annoying to dangerous if you are biking or hitchhiking.
Tucked away in the south-austral area of the country, Carretera Austral area is pretty wild, with often wild weather extremes. It is characterized by thick forests, fjords, glaciers, canals, and steep mountains. It has endless stretches of empty dirt roads surrounded by forests, mountains, glaciers, and lakes, with scenic villages, free campsites, and hot springs along the way.
Never underestimate this road, also known as Ruta CH-7. There is not much traffic on the road. The best time to visit Carretera Austral is between November and April.
