A hot spring area with geysers and steaming vents, offering a unique geological experience. 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.

• On 2025 tour, it was very windy, and Laguna Verde had a bright green color.
• No special permission is required to enter the Uyuni salt flats.
• To add to the experience, we could see flamingos at Laguna Challviri.
• The hot springs of Polques are the perfect place to take a break and relax.
• It is covered with a solid salt crust varying in thickness between tens of centimeters and a few meters.
• The foundation of Salar de Uyuni goes back to a sequence of lakes that filled the Altiplano basin during the Pleistocene.In the past, huge inland lakes—like the prehistoric Lake Minchin—covered the region.

• Many visitors enjoy stopping at the Salt Museum, a quaint space made of salt bricks that features a variety of carved sculptures.
• This is produced by a water layer that sits on top of the salt in the wet season (December to April).

This has direct consequences for lithium extraction, tourism pressure, and local ecosystems. The Salar’s visual magic is not random—it’s atmospheric physics. So the famous mirror effect is not just pretty—it’s physics, geology, and climate working together.

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. Vast reserves of untapped lithium lie beneath the salt flat, and in the early 21st century the Bolivian government discussed options and feasibility for its extraction and production.

As the largest salt flat on Earth, the Salar de Uyuni is widely regarded as one of the most effective natural calibration sites for Earth-observing satellites. Multiple fatal incidents have occurred at the salt flat as a result of poorly maintained vehicles, untrained drivers, speeding, a disregard for the inhospitable conditions, and lack of regulation for tour companies.

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.
Salar de Uyuni is the largest salt flat in the world, with an area of approximately 10,582 square kilometres (4,086 mi2). Sustainability has gained a critical concern as an increasing number of tourists head to Salar de Uyuni.
