Lago Chungará is a high mountain lake at an elevation of 4.517m (14,820ft) above the sea level, located in the Andean Altiplano, in northern Chile. It’s the 10th highest lake in South America.
The road to the lake is called Ruta 11. It’s asphalted, with heavy traffic, especially trucks. Located within the Arica y Parinacota Region in the Lauca National Park, do not travel this pass in severe weather conditions. Avalanches, heavy snowfalls and landslides can occur anytime, being extremely dangerous due to frequent patches of ice. The climb is simply terrible, with a notorius lack of oxygen that tests the organisms and a high degree of steepness. An engine check should be made to all carburated motor vehicles prior to driving at altitude. If the engine looses power in heavy climbs, take off the air filter. This road passes through remote areas, so you need to be prepared. There are no gas stations on the roads. For a trip to Lago Chungará you must fill the tank completely in Arica. If you plan a larger trip you must carry additional gasoline with you.
