Salar de Uyuni
The months in gold are when the weather, the crowds and the prices work out best.
Yes, it is worth going to if you accept the physical discomfort of high altitude. Plan your visit between December and March to see the water reflection effect. Most people allow three days to explore the area properly.
Prices and availability come from GetYourGuide. If you book through one of these we may earn a commission, at no extra cost to you.
Three days is the standard duration for a full tour.
Fly into Uyuni from La Paz or take a long-distance bus to the town of Uyuni.
You do not need a ticket to enter the salt flats themselves, but you must pay for a tour.
The intense cold at night often shocks travelers who only packed for the daytime sun.
The reality of the mirror effect
The mirror effect requires a thin layer of water on the ground. This only happens during the rainy season from December to March. If you visit in the dry months, the ground is just dry, cracked white salt.
Expect bright sunlight and harsh glare at all times. Bring high quality sunglasses and strong sunscreen. The reflection from the ground is as intense as the sun from the sky.

Managing the altitude
You are at a high altitude for the entire trip. Many people feel lightheaded or nauseous during their first day. Drink plenty of water and avoid heavy meals before you arrive.
Do not plan intense physical activities for the first 24 hours. Give your body time to adjust to the thin air. Carry small snacks to keep your blood sugar stable.
Transport and logistics
There is no public transport across the salt flats. You must hire a local driver with a 4x4 vehicle to move between points of interest. Most travelers book a tour in Uyuni town rather than trying to navigate alone.
Your vehicle will be your primary shelter and transport for several days. Ensure your tour company has a good reputation for vehicle maintenance. Breakdowns in the middle of the flats are difficult to fix.

The background
Salar de Uyuni is the largest salt flat in the world, with an area of approximately 10,582 square kilometres (4,086 mi2). It is situated in southwestern Bolivia, within the Daniel Campos Province of the Potosí Department, near the crest of the Andes Mountains, at an elevation of 3,656 m (11,995 ft) above sea level. The Salar was formed as a result of transformations of seven Late Pleistocene lakes whose progressive desiccation led to the accumulation of extensive evaporitic salt deposits. It is now covered by an 8-meter-thick layer of salt, which is extremely flat. The average elevation varies by less than one meter over the entire area of the Salar. The crust serves as a source of salt and covers a pool of brine, which is exceptionally rich in lithium. The large area, clear skies, and exceptional flatness of the surface make the Salar ideal for calibrating the altimeters of Earth observation satellites. Following rain, a thin layer of dead calm water transforms the flat into the world's largest mirror, 129 km (80 miles) across. The Salar serves as the major transport route across the Bolivian Altiplano and is a prime breeding ground for several species of flamingos. Salar de Uyuni

Questions people ask
Do I need a tour guide?
Yes. The terrain is disorienting and lacks roads or signs. A local driver is essential for navigation and safety.
Is the salt flat slippery?
It depends on the season. When dry, it is like walking on concrete. When flooded, it becomes a shallow pool that requires waterproof footwear.
Can I drive myself?
It is not recommended. The lack of infrastructure and the risk of getting stuck in brine pools make it dangerous for inexperienced drivers.
What should I pack?
Pack layers. Temperatures drop significantly once the sun goes down. Bring a high-SPF sunscreen and lip balm to protect against the dry, thin air.
Is there electricity?
Most basic accommodations in the salt hotels have limited electricity. Bring a portable power bank for your phone and camera batteries.
