When it dried, it left behind two modern lakes, Poop\u00f3 and Uru Uru, and two major salt deserts, Salar de Coipasa and the larger Salar de Uyuni. Uyuni originates from the Aymara language and means a pen (enclosure); Uyuni is also the name of a town that serves as a gateway for tourists visiting the Salar. The large area, clear skies, and exceptional flatness of the surface make the Salar ideal for calibrating the altimeters of Earth observation satellites. The Salar was formed as a result of transformations of seven Late Pleistocene lakes whose progressive desiccation led to the accumulation of extensive evaporitic salt deposits.<\/p>\n
Solar de Mana\u00f1a geysers are located at an altitude of more than 15,912 ft\/ 4,850m. Make sure to charge your devices during this time. Note that to enter Reserva Nacional de Fauna Andina Eduardo Avaroa, you need to pay an entrance fee of Bs 150 (not included in the tour price). In reality, its deep red color comes from red sediments and the pigments of algae and microorganisms living in the lake. According to the local folklore, the water in Laguna Colorada is the blood of the Gods. It sits at an altitude of 14,000 ft\/ 4,270 m in Eduardo Avaroa Andean Fauna National Reserve, close to the Chilean border.
\nThe island is a remnant of an ancient volcanic formation and was once part of a prehistoric lake. It’s a unique landscape featuring giant cacti, some reaching over 10 meters tall, thriving amidst the harsh, salty environment. The salt crusts and brine pools support a rich diversity of microbial communities, including halophilic archaea and bacteria that have adapted to the high salinity and other extreme conditions. The Salar de Uyuni is characterised by high salinity, low humidity, and a significant altitude, creating a challenging environment for most life forms. The savage beauty of this vast salt desert makes it one of South America’s most awe-inspiring spectacles.<\/p>\n
Plenty of travellers opt for the most basic Salar de Uyuni tour and have a fantastic time. There are options for one, two or three-day tours to Salar de Uyuni (some companies also have four-day options). Note that Chile is a much more expensive country to travel than Bolivia and as such tours booked and beginning in San Pedro tend to be more expensive than those in Bolivia. Most tours will visit the geysers at sunrise when the dawn light and rising steam combine to create an ethereal atmosphere.
\nAcross more than 10,000 square kilometers, the elevation difference is barely around one meter.This is almost impossible in natural landscapes. 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\u2014like the prehistoric Lake Minchin\u2014covered the region.
