A Complete Travel Guide to the World’s Largest Salt Flat
Welcome to Salar de Uyuni, the most surreal and breathtaking destination in Bolivia — and arguably, the entire planet. Stretching over 10,500 square kilometers, it’s not just the largest salt flat in the world, it’s a visual spectacle that turns the earth into a giant mirror of the sky.
Whether you’re a travel photographer, adventure lover, or simply someone who wants to stand where the earth touches the heavens, Salar de Uyuni is a must-visit bucket list experience.
📍 What is Salar de Uyuni?
Salar de Uyuni is located in southwestern Bolivia, formed by prehistoric lakes that evaporated over millennia, leaving behind a crust of dazzling white salt.
During the wet season (December to April), a thin film of rainwater transforms the salt flat into a massive mirror, reflecting the sky so perfectly that the horizon vanishes.
In the dry season (May to November), the surface turns into a vast, cracked crust of hexagonal salt tiles, stretching to the horizon in all directions — like something out of a sci-fi movie.
