Driving the international Chungara-Tambo Quemado Pass
Paso Chungara-Tambo Quemado is an international high mountain pass at an elevation of 4.687m (15,377ft) above the sea level located on the border of Chile and Bolivia.
Set high on the Cordillera Occidental of the Andes, the road to the summit is totally paved. It’s called Ruta Nacional 4, in Bolivia and Carretera Internacional CH 11, in Chile. It's one of the principal Chile-Bolivia passes in the central Andes as it connects the Bolivian city of La Paz with its nearest seaport Arica, the capital of the northernmost region of Chile. The road is heavily used by trucks. The pass is on the border between Region XV, in Chile and Departamento de Oruro, in Bolivia.
This road is usually open all year. With transit enabled for all types of vehicles, the pass is 157 km (97.5 miles) long running from Curahuara de Carangas (in Oruro Department, Sajama Province in Bolivia) to Putre (the capital of the Parinacota Province in the Arica-Parinacota Region of Chile).
