The Ruta de los Salares, the Salt Flats Route, is a long day trip into the high desert south and east of San Pedro de Atacama, and it offers some of the region's emptiest and most spectacular scenery. The route links a series of salt flats, lagoons and volcanoes along the altiplano, with long straight roads, tracks of white crust and the cones of dormant volcanoes on the horizon. Because it is less visited than the main lagoons, you often have places entirely to yourself, and the sense of remoteness is part of the appeal. A highlight on some itineraries is the Pacana caldera, a huge volcanic basin where eruptions millions of years ago shaped the surrounding landscape. In it stand the Monjes de la Pacana, the Monks of Pacana, tall, slender rock formations that look like hooded figures against the sky. Guides explain the geology, point out vicuñas and other wildlife, and stop at viewpoints for photographs and a picnic. The mix of volcanic landscape, salt, and silence suits travellers who have already seen the best-known sights and want something wilder.
How it works
This is a full-day trip, usually ten hours or more, by minibus or 4x4 along remote roads. Itineraries vary, so check which salt flats, lagoons and viewpoints are included, whether lunch is provided, and what the entry fees are. Because conditions in the highlands can change, operators sometimes alter the route, and roads can be closed by weather or maintenance.
What to expect
The altitude is high, around 4,000 m at several stops, so spend a few days acclimatising before going. Dress warmly, as it is windy and cold even on sunny days, and carry water, snacks and sun protection. Facilities are minimal, with few toilets and no shops on the route, so go prepared. Stay on marked paths and do not remove rocks, as the salt crust and rock formations are fragile.
Making the most of it
Choose this trip if you have a few days in the region and want to see beyond the main highlights, and combine it with the Altiplanic Lagoons only if you have time for a second full day. Take binoculars for wildlife and a camera with a wide lens for the scenery. Small groups give a more flexible experience, with time to linger. If you want a lot of solitude and are comfortable with long drives, this is one of the most rewarding days you can spend in the Atacama.
