The Uyuni Salt Flats are one of those destinations that amaze you from the very first moment. Its landscapes change with the seasons, offering completely different experiences, from exploring the vast salt desert to witnessing the famous mirror effect. In this guide, you’ll discover what to do, which places to visit, and how to make the most of your trip.
Why Visit the Uyuni Salt Flats?
Located in southwestern Bolivia, the Uyuni Salt Flats are the largest salt flat in the world, covering more than 10,000 km² (3,900 sq mi). Its vast white expanse, islands covered with giant cacti, high-altitude lagoons, and the spectacular mirror effect during the rainy season make it a truly unique destination. Beyond its extraordinary natural beauty, it is part of Bolivia’s natural heritage and one of the most photographed places in South America thanks to the incredible variety of landscapes it offers in a single journey.
Top Places to Visit in the Uyuni Salt Flats
The Uyuni Salt Flats are home to remarkable natural and historical attractions included in most tours. Each stop offers a different experience, from unique landscapes to sites of great cultural and geological significance.
The Uyuni Salt Flats
The main attraction is the immense salt plain stretching across more than 10,000 km² (3,900 sq mi). During the dry season, you can walk across a completely white landscape and capture the classic perspective photos, while in the rainy season, a thin layer of water creates the famous mirror effect, reflecting the sky in a breathtaking way.
Incahuasi Island
Located in the middle of the salt flats, Incahuasi Island is famous for its giant cacti, some of which are several centuries old. Marked trails lead to natural viewpoints where you can enjoy panoramic views of the endless salt flats, offering a striking contrast between the volcanic rock and the brilliant white salt surface.
Train Cemetery
Just a few kilometers from the town of Uyuni lies this historic site, home to old locomotives and railcars dating back to the late 19th and early 20th centuries, once used during Bolivia’s railway boom. Today, it is one of the area’s most photographed attractions and can easily be visited by vehicle before entering the salt flats.
Eyes of the Salt Flats
The Eyes of the Salt Flats are small natural springs where groundwater rises through the salt crust, creating visible bubbles on the surface. This geological phenomenon reveals the presence of underground water currents beneath the salt flats and helps explain how this unique ecosystem is sustained.
Dakar Monument
This monument was built to commemorate the Dakar Rally’s passage through Bolivia between 2014 and 2018, when the Uyuni Salt Flats were part of one of the competition’s most iconic stages. Today, it is a popular stop for taking photographs and enjoying one of the most representative views of the salt flats.
Best Places to Visit on Multi-Day Tours
If you choose a 2-day, 3-day, or longer tour, you’ll discover landscapes that extend far beyond the salt flats. These routes explore the Eduardo Avaroa Andean Fauna National Reserve, where you’ll find stunning lagoons, deserts, and geothermal areas.
Colorada Lagoon
Colorada Lagoon is one of the most iconic landscapes in the Bolivian Altiplano thanks to the reddish color of its waters, created by algae and minerals. It is also home to thousands of Andean flamingos, whose vibrant presence contrasts beautifully with the surrounding volcanoes and mountains, making it one of the most anticipated stops on the tour.
Green Lagoon
Located at the foot of the majestic Licancabur Volcano, Green Lagoon is known for the striking color of its waters, which changes depending on the wind and the sunlight. It is one of the final destinations on many tour circuits and offers a landscape completely different from that of the salt flats.
Siloli Desert
The Siloli Desert impresses visitors with its arid terrain and unusual rock formations sculpted by the wind over thousands of years. It is home to the famous Stone Tree, a rock formation shaped like a tree that has become one of the natural icons of southwestern Bolivia.
Sol de Mañana Geysers
The Sol de Mañana Geysers are an extensive geothermal area featuring fumaroles, mud pools, and steam vents that constantly rise from the ground. The best time to visit is at sunrise, when the cold temperatures make the towering columns of steam much more visible.
Polques Hot Springs
The Polques Hot Springs are natural thermal pools located within the Andean reserve, making them the perfect place to relax after several days of exploring. It’s recommended to bring a swimsuit, towel, and warm clothing, as the outside temperature is usually very low, especially during the early morning hours.

Is It Better to Take a Tour or Visit Uyuni Independently?
