Best Time for a Salar de Uyuni Safari: Shoulder Season Guide
The Salar de Uyuni is the world's largest salt flat — a 10,582 square kilometre expanse of white at 3,656m altitude in the Bolivian Altiplano that produces the world's most famous mirror effect when covered with a thin film of water.
April–May and August–September are the shoulder windows — April/May catch the end of the rainy season when the mirror effect is still active, while August–September bring the clearest dry season conditions for the white salt and coloured lagoons.
