The most amazing place I have ever been to. My words can't do it justice so here are some facts:
Altitude - 2400m
Atacama desert - driest in the world
Salar de Atacama - 3rd largest salt lake in the world
Moon and death valleys - their names say it all
Altiplanic lagoons - lakes in the high (4100m ) Andean plateau
El Tatio Geysers - 80 active geysers at 4200m. Very, very cold at 6am
Loads and loads of cool restaurants, bars, cafes and artesans
