In the North of the Salar of Uyuni, the “fish island” is covered by very high cactus, from 10 to 12m height. An apparition from nowhere and a little bit phantasmagorical, because having a small island of wilderness in a salted desert is improbable. Adaptation to climatic conditions that are particularly difficult in the Salar of Uyuni created this special biodiversity. It is not so much visited because travelers prefer her twin, the island of Incahuasi. Warning! There is often confusion with the name of this last one, the Island of Incahuasi is often called, wrongly, the fish island. To recognize them on a map, or in Google Earth, look to the shapes. The fish island is characteristic for its elongated shape… as a fish!
