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 the extreme north of Chile. It’s the 10th highest lake in South America.
The road to the lake is called Ruta (Carretera Internacionl CH11) 11. It’s paved, with heavy traffic, especially trucks. Located within the Arica y Parinacota Region in the Lauca National Park, the road is 25km long, running west-east from Parinacota, one of the highest elevation human habitations in the world in Putre towards Chungara-Tambo Quemado Pass.
Remember this is a mountainous area, climbing up a high mountain, with a notorius absence of oxygen. An engine check should be made to all carburated motor vehicles prior to driving at altitude. If the engine loses power in heavy climbs, take off the air filter. 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. Remember to take stunning photos of volcanoes reflected in the lake's surface. Altitude and extreme weather are always a factor.
