Antofagasta to San Pedro De Atacama

Antofagasta - Baquedano - Peine - Toconoa - San Pedro de Atacama



This is a great alternative route to reach San Pedro de Atacama from Antofagasta, avoiding the busy dangerous roads via Calama (Ruta 5, Ruta 25 & Ruta 23).

The route follows mining roads across the Atacama Desert with an excellent unpaved road surface and relatively quiet traffic, with friendly respectful truck drivers offering assistance, food and water on numerous occasions.

Highlights include:

  • Atacama Desert - enjoy the peaceful solitude and the unpolluted night skies

  • Salar de Atacama - crystalline projections for as far as the eye can see

  • Peine - visit this old Atacameño village, see the ruins and cave paintings or take advantage of the hot springs

  • Laguna Chaxa (Reserva Nacional Los Flamingos) - watch the flamingos feed on brine shrimp

  • Laguna Cejar -  take a dip in the ultra saline laguna if you are in the right season

  • San Pedro de Atacama - a tourist haven in the midst of the desert with many atractions to visit


The remote section is on the mining roads between Baquedano and Peine. There are no shops, settlements or natural sources of water, so you will need to carry food and water for 208km. We took water (approx. 12L each) and food for 4 days to be on the safe side, but made it in 3 days. The truck drivers gave us an additional 5L of water, but we turned down many other offers due to the weight of carrying water. Plenty of help was available, if required, on this section from the mine workers.


'Agua por favor' - keep an eye out for the only tree on this section, literally begging for water - and quench its thirst if you can spare a few hundred mls of water for it to survive out there
