Geographical context

Located in the far north of Chile, Cerro Milagro is part of the western foothills of the Western Andes. The steep relief, formed by ancient volcanic deposits, contrasts with the surrounding puna plains. The hill overlooks valleys crossed by small seasonal streams, and offers views of the Parinacota and Pomerape volcanoes.

Natural environment

The flora and fauna are strongly influenced by the altitude and aridity. There are yaretas (Andean shrubs), vicuñas, viscaches and high Andean birds such as the James's flamingo. The region is sparsely inhabited, used mainly for the traditional grazing of llamas and alpacas.

Its moderate altitude makes it an accessible goal for acclimatization before undertaking higher ascents in the region.
