Salar de Uyuni, Month by Month: When to Visit Bolivia’s Salt Flats

There is no bad time to visit the Salar de Uyuni Salt Flats of Bolivia — only very different experiences depending on when you go. Travel between December and March and you step into a vast, sky-reflecting mirror that has to be seen to be believed. Come between June and October and you get a bone-white, geometrically patterned expanse so otherworldly it doubled as a planet in Star Wars. The shoulder months give you a little of both.

Most travelers combine Uyuni with Cusco, Puno, Lake Titicaca, and La Paz, using the Desaguadero or Kasani border crossings between Peru and Bolivia. Allow at least a 3-day / 2-night circuit if you want both the salt flats and the colored lakes and geysers to the south; one-day tours focus mainly on the flats, Isla Incahuasi, and the Train Cemetery. Whichever season you choose, we have a ready-made route that connects it all.

Quick answer: which season is right for you?

When	Best for
December–March	The mirror effect — flooded flats, infinite reflections, unforgettable photos
April–May & November	Shoulder season — patches of water alongside dry salt, fewer crowds, moderate prices
June–October	Classic white-salt photos, full access to islands and circuits, clearest skies

What Uyuni is like, month by month

December–March: rainy season (mirror season)

• Seasonal rains flood the flats, creating the world’s largest natural mirror — an unbroken reflection of sky and clouds that stretches to every horizon
• The corrosive, mineral-laden spray limits 4×4 vehicles to a slow crawl, making large sections of the 7,500 sq mi (12,000 km²) salar difficult or impossible to reach
• Access to Isla Incahuasi, Thunupa Volcano, and the Chiquili Cavern is greatly limited or closed entirely
• Rubber boots, rain gear, and camera protection are essential

April–May: transition (shoulder season)

• Rains ease off; patches of shallow water sit alongside expanding areas of dry salt for a mix of both experiences
• Access to Incahuasi and other sites gradually returns
• Cooler nights; fewer visitors than peak dry season

June–August: dry season (high season)

• The surface hardens into a brilliant white expanse covered in striking pentagonal geometric figures
• Full access to Isla Incahuasi, the Train Cemetery, and multi-day circuits to the colored lakes and geysers
• Nights are very cold at 11,890 feet (3,625 m) above sea level; strong UV radiation during the day — layers, sunblock, and quality sunglasses are non-negotiable
• Peak tourist season — book accommodation and tours in advance

September–October: late dry season

• All the advantages of dry season with slightly milder temperatures and thinner crowds than the July–August peak
• One of the best times to visit if you want full access and a quieter experience

November: shoulder into rainy season

• First rains begin to arrive — occasional shallow water creates early reflections
• Most sites are still reachable, making this a good compromise month

What to pack

Rainy season (December–March)

• Rubber boots or waterproof sandals — you will be wading
• Rain jacket and warm layers for the afternoon, when wind picks up and temperatures drop sharply
• Camera protection: a waterproof case or dry bag is essential — the salty spray is corrosive enough to damage 4×4 transmissions, and it is equally unkind to electronics. Bring microfiber cloths for wiping lenses, phone screens, and mirrorless camera bodies
• Extra batteries and a high-capacity SD card — cold air drains batteries fast

Dry season (May–October)

• Strong SPF sunblock — the white salt reflects UV from below as well as above
• Good UV-protective sunglasses
• A warm hat or cap (inexpensive alpaca versions are widely available in Colchani, the main entrance point, for around 30 Bolivianos / ~$4 USD)
• Insulating layers for very cold nights at altitude
• Extra batteries and large-capacity SD card — you will take more photos than you expect

Highlights you can visit most of the year

Visit the Salar de Uyuni Salt Flats of Bolivia to experience a location unlike any other

The Salar de Uyuni altiplano is one of the world’s most extraordinary photo opportunities — a lost horizon where sky and earth become indistinguishable. In the rainy season, that means wading through a few centimeters of water to set up perspective-bending shots or capture a perfect reflection. In the dry season it means stepping out onto a blindingly white geometric canvas that stretches further than the eye can follow.

The wide-open, luminescent expanse is so otherworldly that Salar de Uyuni served as a filming location for Star Wars: Episode VIII — The Last Jedi in June 2016, standing in for a Rebel Alliance base on the planet Crait.

Visa Requirements to visit the Salar de Uyuni Salt Flats of Bolivia

Bolivia has recently removed tourist visa requirements for citizens of eight countries, including the United States, Israel, South Korea, South Africa, Bulgaria, Malta, Romania, and the United Arab Emirates, placing them in the same visa-free category as most Europeans and Canadians for short visits of up to 90 days per year.
