The Atacama Desert is the driest non-polar place on Earth with the Tatio Geysers at sunrise, the Valle de la Luna's salt formations at sunset, and ALMA observatory's clear skies attracting global astronomers.
Cool dry season with crystal-clear stargazing nights, Tatio Geysers at peak photogenic 4,300m altitude sunrise, and salt flats accessible without summer's afternoon dust storms.
Altiplanic winter brings afternoon storms over the high Andes, but mornings stay clear and the Lagunas Altiplánicas at peak flamingo concentration.
Coldest desert nights with stargazing at peak clarity (MAX -5°C at altitude), San Pedro de Atacama walking pleasant by day, and salt flats at maximum reflectivity.
Spring shoulder with desert flowering possible in rain years (Desierto Florido), and the high lagoons full with breeding flamingos in their pink summer plumage.
