San Pedro de Atacama

San Pedro sits at 2,400 metres on an oasis where the San Pedro river reaches the salar, and it has been occupied for thousands of years - the Atacameño or Likan Antai people farmed here long before the Inca road system passed through and long before the Spanish. The town today is low adobe walls, unpaved streets kept that way deliberately, and a dense concentration of tour agencies, hostels and restaurants serving the geysers, lagoons and valleys around it. Water is the constraint on all of it: tourism, agriculture and the lithium industry draw on the same limited aquifer, and the argument over that is the town's real subject.

What you actually see

• An adobe oasis town - unpaved streets kept unpaved on purpose.
• Atacameño ground - occupied for thousands of years before the Inca.
• The base for the whole circuit - geysers, lagoons, valleys and salt flats.
• A water argument underneath - tourism, farming and lithium on one aquifer.

When to go

Year round; winter nights fall well below freezing at 2,400 metres. Several days.

Honest expectations

Prices are high for Chile and rise further in season. Altitude affects some people even here, before anything higher. Almost everything is sold as a tour. The town is small and can feel saturated in peak months.
