Uyuni Travel Guide 2026: Salar de Uyuni, Tours, Best Time to Visit, Costs & Tips
Uyuni is the gateway to the Salar de Uyuni, the world's largest salt flat and one of the most surreal landscapes on Earth. Covering more than 10,000 km² at about 3,656 metres above sea level, the salar is a blinding white expanse of hexagonal salt tiles stretching to the horizon. In the rainy season, a thin layer of water turns it into the world's largest natural mirror, reflecting the sky so perfectly that the horizon disappears. Beyond the salt flat, multi-day tours explore the Eduardo Avaroa Andean Fauna National Reserve, with red and green lagoons, flamingos, geysers, hot springs and volcanoes, often continuing to San Pedro de Atacama in Chile. The town of Uyuni itself is small and dusty, but it's the starting point for unforgettable adventures. This Uyuni travel guide covers the best time to visit, the top things to do, where to stay, how to get there and around, costs, entry rules and practical tips.
Best Time to Visit Uyuni
Wet season (December–April) is the time for the famous mirror effect, especially from January to March, when rain creates a reflective layer of water. Some areas may be inaccessible due to flooding, and multi-day routes may change.
Dry season (May–November) offers clear skies, bright white salt and access to all areas, including Incahuasi Island and the southern lagoons. Nights are extremely cold, often -10°C to -20°C in winter (June–August).
Best of both: April and November can offer a mix of dry salt and occasional reflections.
Top Things to Do in Uyuni
1. Salar de Uyuni
Drive across the endless white salt flat, take creative perspective photos and watch sunrise or sunset over the salt. In the wet season, experience the mirror effect.
2. Train Cemetery (Cementerio de Trenes)
Rusting steam locomotives from the early 20th century, abandoned on the edge of town when mining declined.
3. Incahuasi Island
A rocky "island" in the middle of the salt flat, covered with giant cacti, some over 1,000 years old, with panoramic views. Only accessible in the dry season.
4. Colchani
A village at the edge of the salar where locals process salt by hand, with a small salt museum and craft markets.
5. Laguna Colorada
A striking red lagoon in the Eduardo Avaroa Reserve, home to thousands of James's and Andean flamingos.
6. Sol de Mañana Geysers
Bubbling mud pools and steaming fumaroles at nearly 5,000 metres, best seen at dawn.
7. Laguna Verde and Licancabur Volcano
An emerald-green lagoon at the foot of the Licancabur Volcano, near the Chilean border, plus the Polques hot springs, perfect for a morning soak.
Also worth visiting: the Dalí Desert (Desierto de Siloli) with surreal rock formations, the Árbol de Piedra (Stone Tree), the Salt Hotel and the Pulacayo ghost mining town.
Typical 3-Day Uyuni Tour
Day 1 – Salar de Uyuni: Visit the Train Cemetery, Colchani, the Dakar monument, the flags monument and Incahuasi Island, then watch sunset on the salt.
Day 2 – Lagoons: Drive through high-altitude deserts past colourful lagoons with flamingos, the Árbol de Piedra and Laguna Colorada.
Day 3 – Geysers and hot springs: Visit the Sol de Mañana geysers at sunrise, soak in the Polques hot springs, see Laguna Verde and either return to Uyuni or cross to San Pedro de Atacama in Chile.
Choosing a Responsible Tour Operator
Uyuni has dozens of tour operators of varying quality. Choose one with good reviews, reliable 4x4 vehicles, sober drivers, sufficient food and water, first aid kits and oxygen. Ask about the vehicle's condition, the number of passengers (usually six per jeep) and accommodation standards. Accidents have occurred on the salt flat, so safety should come first.
The Salt and Lithium of Uyuni
The salar contains an estimated 10 billion tonnes of salt and one of the world's largest reserves of lithium, used in batteries for electric vehicles and phones. Bolivia has been developing lithium extraction with foreign partners, raising debates about economic opportunities and environmental impacts on local communities and fragile ecosystems.
Food in Uyuni
Most tours include simple meals. In Uyuni town, try llama steak, quinoa soup, pique macho (beef, sausage and fries) and pizzas at tourist restaurants. Bring snacks and plenty of water for the tour.
