Salar de Uyuni Salt Flat Mirror

This 4,000-square-mile salt desert becomes the planet’s largest mirror when covered by a thin layer of water during Bolivia’s rainy season (December-April). The perfectly flat surface reflects clouds and sky, creating an otherworldly infinity effect that draws photographers from around the globe. During dry season, the salt forms geometric polygonal patterns stretching to distant volcanic peaks on the horizon.

Access from Uyuni town via rough salt roads — high-clearance vehicles recommended though tours run daily in standard vans. The salt is corrosive, so rinse your vehicle thoroughly afterward. Bring sunglasses and serious sun protection — the white surface reflects intense UV. Weather changes fast, and GPS can be unreliable on the featureless expanse.
