Salar de Uyuni is one of the most impressive destinations in Bolivia and the whole world. Famous for its vast salt desert, which at certain times of the year turns into a gigantic mirror, this place attracts thousands of tourists who want to live a unique experience. Here we tell you everything you need to know to plan your visit to the Salar de Uyuni, including how to get there from Chile.

Where is the Salar de Uyuni?

The Salar de Uyuni is located in southwestern Bolivia, in the department of Potosí. With an area of more than 10,000 square kilometers, it is the largest salt flat in the world. It is a popular destination among tourists, especially those traveling from Chile, as it is close to the border and accessible from the Atacama Desert, another world-famous natural destination.

What is the best time to visit the Salar de Uyuni?

The best time to visit the Salar de Uyuni depends on what you want to see and experience:

• Rainy season (January to March): During these months, it is likely that the salt flat will be covered with a layer of water that creates the famous “mirror effect,” where the ground reflects the sky. This produces an astonishing visual phenomenon, making the horizon disappear and giving the sensation of walking in the sky. It is the ideal time for those seeking a magical and unique experience; however, this will depend on the season’s weather changes.

• Dry season (May to October): In this period, the salt flat is completely dry, and you can see the hexagonal salt formations on the surface. The dry season allows more freedom to explore the salt flat and visit areas like Incahuasi Island, an island in the middle of the salt flat with giant cacti and impressive panoramic views. It is also the best time for trekking and exploring nearby areas.

How Many Days are Needed to Visit the Salar de Uyuni?

For a basic visit to the Salar de Uyuni, one day is enough to tour nearby areas and experience the salt flat. However, for those who want to explore in-depth and visit other points of interest in the region, a 4-day tour is recommended.

Some additional sites you can include are:

• Incahuasi Island: Located in the heart of the salt flat, this island is filled with giant cacti and offers a 360-degree view of the salt flat. It is an ideal place to enjoy unique sunrises and sunsets.

• Colored Lagoons: The Colorada and Verde Lagoons, with their vibrant waters and the presence of Andean flamingos, are popular stops on longer tours and are located within the Eduardo Avaroa Andean Fauna National Reserve.

• Geysers and Hot Springs: On the route of multi-day tours, you can enjoy hot spring baths and visit areas of geothermal activity.

Weather in the Salar de Uyuni

The climate in the Salar de Uyuni is extreme, with temperatures that vary drastically between day and night due to the altitude and desert terrain:

• In the dry season: Daytime temperatures usually range between 15°C and 20°C, but at night they can drop significantly, reaching as low as -15°C during the coldest months of June and July. Nights are cold, and conditions can be harsh, so warm clothing is recommended.
• In the rainy season: Temperatures are a bit higher, with averages between 15°C and 25°C during the day. Nights are still cold, though not as much as in the dry season. It’s important to bring waterproof clothing if you plan to visit during this period, as the terrain may be covered with water, and walking on wet surfaces may be necessary.
