Crossing from Bolivia to Chile is a journey through the stark, high-altitude landscapes of the Atacama Desert and the Altiplano. This border, a historical product of the 19th-century War of the Pacific which left Bolivia landlocked, is one of the driest and highest in the world. It offers dramatic scenery of active volcanoes, vibrant mineral-colored lakes, and sprawling salt flats under an intensely blue sky. You have three main options for this crossing. The most utilized route for travelers is between Tambo Quemado in Bolivia and Chungará in Chile. This pass takes you through the stunning Lauca National Park, home to pristine lakes and the snow-capped Parinacota and Pomerape volcanoes.
Other crossings are located at Ollagüe, which serves a railway line as well as a road, and the more remote Hito Cajón, providing access from the Uyuni Salt Flats area to San Pedro de Atacama in Chile. Be thoroughly prepared for the altitude, which averages over 4,000 meters (13,000 feet) and can cause serious illness. The journey requires careful planning, as services are extremely limited, and the weather can be severe, with freezing winds and potential snowfall even outside of the main winter season. This is a truly adventurous crossing that rewards the well-prepared traveler with unforgettable views.
