Deserts, lagoons and volcanoes

On the second day of our trip, we enjoyed beautiful desolate landscapes, where volcanoes and lagoons showed up in the desert. We drove from the Uyuni salt flat to the Eduardo Avaroa Andean Fauna National Reserve, located in the Sur Lípez Province.

The Ollagüe Volcano is located in the border between Chile and Bolivia and has intense fumarolic activity. With a height of 5868m is mined still today for the extraction of sulphur.

Huge yareta plants can be found on the old lava flows from the Ollagüe Volcano. The plant grows about 1.5cm per year, building up big green rock-shaped formations. Many yareta plants are estimated to be a few thousand years old.

'Árbol de piedra' (stone tree) is a very photographed wind eroded rock in the Siloli desert.


A James's flamingo in the Laguna Colorada (red lagoon). The red colour comes from microscopic red algae and red sediments. The flamingo gets its pink colour from eating the algae.

The Laguna Colorada has white "islands" of borax, which is a source of the important boron. used in detergents, cosmetics or in the metallurgy industry. Many of the lagoons in the area abound in it, and are therefore mined.
