There are tours that run directly from the Chilean town of San Pedro de Atacama, which is close to the Bolivian border.

Isla Incahuasi, also known as Cactus Island, is a small, rocky outcrop located in the middle of the Salar de Uyuni, the world’s largest salt flat, in Bolivia. The ideal time for stargazing is during the dry season (April to November) and particularly around new moon phases, when the skies are clear and dark. It holds half of the world’s lithium reserves and its vast, flat surface makes it an ideal location for calibrating satellite radar altimeters, which measure surface topography.
Here’s all you need to know about this unique experience. The fields of salt, extending as far as the eye can see and backed by distant mountains, create one of the most dramatic and unique vistas on Earth. Salar de Uyuni is the remains of an enormous prehistoric lake. In February 2024, the Copernicus Sentinel-3B mission conducted calibration activities over the salar for its Synthetic Aperture Radar Altimeter (SRAL). As part of its validation strategy, CryoSat-2 has relied on the salar, where its Interferometric synthetic-aperture radars (InSAR) capabilities were reinstated to enhance the precision of altimetric observations. The mission focused on calibrating radar-based measurements of surface topography.

  • Bring sunscreen, sunglasses, lip balm, and a jacket (or two) of clothing – the day and night can be extremely different.
  • But in the wet season, a thin layer of water transforms the surface into the world’s largest mirror, reflecting the blue altiplano sky and the clouds.
  • The tour takes you through elevations ranging from about 3,600 m to 4,800 m.
  • On our 2025 tour, the sunset was included in the itinerary, and we had wine and snacks while watching the sunset.
  • The best time to visit Salar de Uyuni depends on what you want to see.
  • (There are no day buses for some reason.) Local buses can be booked on busbud.com.

One-day tours generally visit the Train Graveyard, Colchani, salt flats and Incahausi Island. If taking a multi-day tour of the salt flats, it’s likely you’ll spend the night at one of the area’s unique salt hotels.

  • During the rainy season, water can fill parts of the salt flat, creating a stunning mirror-like effect.
  • The dry season, which lasts from May to November, offers clear skies and the opportunity to observe the unique hexagonal salt patterns.
  • When water levels dropped, evaporation increased.And every time the water pulled back, it left behind thick salt deposits, clays, silts, and evaporite minerals.
  • When visiting the breathtaking salt flats, consider enhancing your experience by staying at a hotel made entirely of salt.

The visitors can see the panoramic views of the salt expanse making it appear to be infinite in all directions as seen on top of the mountain.

You should be an experienced cyclist and be prepared for long distances. I spent three months travelling around Bolivia, and my trip to Salar de Uyuni was the real highlight.

On both tours our drivers found spots with no one else around and brought dinosaur toys and wine bottles to use in the shots. The Dakar monument is made of salt, and the flags were left by travelers during their visits. It’s located near the Argentine border and a bit farther from the Uyuni salt flats. In Uyuni, there are plenty of travel agencies offering Salar de Uyuni tours. Unfortunately, standard 2-day tours don’t include these highlights.

On 2025 tour, it was very windy, and Laguna Verde had a bright green color. So there is no guarantee the lake will be green when you come there.

These islands are the tops of ancient volcanic domes that remained above water even when the whole area was a lake.As the lakes dried and the salt crust formed, the domes stayed as isolated high points. Since the salt flat is already extremely smooth, this water film becomes a near-perfect reflective layer. When water levels dropped, evaporation increased.And every time the water pulled back, it left behind thick salt deposits, clays, silts, and evaporite minerals. This is produced by a water layer that sits on top of the salt in the wet season (December to April). It’s also possible to take private tours for the ultimate customised experience.
Collectively, these features make the Salar de Uyuni approximately five times more effective for satellite calibration than the surface of the open ocean.

Because of its location, large area, and flatness, the Salar is a major car transport route across the Bolivian Altiplano, except when seasonally covered with water. However, except for January, even in the rainy season the number of rainy days is fewer than 5 per month. It is covered with a solid salt crust varying in thickness between tens of centimeters and a few meters. Lacustrine mud that is interbedded with salt and saturated with brine underlies the surface of Salar de Uyuni.
