Uyuni Salt Flats

The Uyuni Salt Flats (Salar de Uyuni) are the world’s largest salt flat, a surreal, blinding-white expanse stretching over 10,000 square kilometres across the Bolivian Altiplano. When a thin layer of water covers the crust, the sky reflects perfectly, creating an otherworldly mirror effect that attracts photographers and dreamers from around the globe.

Highlights & What to See

• Salar de Uyuni – Walk on the hexagonal salt crust and capture mind-bending perspective photos on the endless white plain.
• Isla Incahuasi – A cactus-covered island rising from the salt, offering panoramic views and a chance to see giant cacti up to 10 metres tall.
• Train Cemetery – Rusting locomotives from the early 20th century, left to decay in the desert just outside Uyuni town.
• Colchani Salt Processing – Visit the salt mounds and traditional processing huts where locals harvest and process salt.
• Sunrise & Sunset on the Salar – The changing light paints the salt in pastel hues; a sunrise tour is especially magical during the wet season.

Suggested Time to Spend

Most visitors spend one to three days on the salt flats. A classic day trip covers the salt flat, Incahuasi Island, and the Train Cemetery, but to fully experience the mirror effect and the high-altitude desert, a two- or three-day 4WD tour is recommended. This allows you to visit colourful lagoons, flamingos, geysers, and hot springs in the surrounding Eduardo Avaroa National Park. The best time to see the mirror effect is January to March (wet season), while the dry season (April–November) offers easier access to the entire flat.

Nearby Areas Worth Combining

• San Pedro de Atacama, Chile – Cross the border into Chile’s Atacama Desert, a popular route for a combined salt flats and desert itinerary.
• Potosi – A historic silver-mining city with the famous Cerro Rico mine, about a six-hour drive from Uyuni.
• Lake Titicaca – South America’s largest lake, shared by Bolivia and Peru, with cultural sites like Copacabana and the Isla del Sol.
• La Paz – Bolivia’s dramatic capital, a gateway to the salt flats and a city of cable cars, markets, and colonial architecture.
