Same origin as Uyuni. No crowds. The story of the altiplano's oldest people.
~40,000 BC
Geological origin
Salar de Coipasa and Salar de Uyuni were once part of the same prehistoric lake — Lake Minchín — which covered the altiplano around 40,000 years ago. As the waters evaporated, they left the planet's greatest salt concentration split into two basins.

The Chipaya: before Tiwanaku
The Chipaya people speak Uru-Chipaya — a language with no genetic relationship to Aymara or Quechua. Linguists and archaeologists consider them descendants of the altiplano's first inhabitants, predating the Tiwanaku civilisation (300–1000 AD) and the Aymara expansion.

The alternative salt flat
While Salar de Uyuni receives over 400,000 visitors a year, Salar de Coipasa rarely sees more than one or two vehicles a day. Same geological origin, same salt, same volcano on the horizon — and total silence. Coipasa is Uyuni without Uyuni.

Ruta La Vicuña
Uyuni → Coipasa → Sajama → La Paz. One of Bolivia's most spectacular altiplano circuits, little known outside the independent traveller community. Four days of pure altiplano without repeating a landscape.
