What You'll Learn
The Bolivian word for salt flats is Salar de Uyuni
The Bolivian word for salt flats is "Salar de Uyuni". This vast expanse of salt deposits spans more than 4,000 square miles in the Daniel Campos Province in southwest Bolivia, near the crest of the Andes Mountains. It is considered one of the most remarkable vistas in South America, if not the world, and its mirror-like quality when wet makes it a photographer's dream.
The Salar de Uyuni was formed thousands of years ago when a massive prehistoric lake dried up, leaving behind a thick crust of salt that extends to the horizon. During certain times of the year, nearby lakes overflow, and a thin layer of water transforms the flats into a stunning reflection of the sky. This natural phenomenon, known as the "`mirror effect`", attracts tourists from all over the world.
The Salar de Uyuni is not just a breathtaking visual spectacle but also a valuable source of salt and lithium for Bolivia. The lithium contained in the salt flats is an essential component of batteries that power electric vehicles, smartphones, and other devices. Additionally, the area serves as a breeding ground for several species of flamingos and is home to around 80 species of birds.
The best time to visit the Salar de Uyuni depends on what you want to see. The wet season, from December to April, offers the famous mirror effect, while the dry season, from May to November, provides colder temperatures and a harder ground that allows for easier driving across the landscape. However, the dry season may not be the best time to capture the mirror-like effect of the flats.
The town of Uyuni in Bolivia is the most popular starting point for tours of the salt flats. It is easily accessible by bus, train, or plane, and tourists can book tours in advance or explore the options available in the town. San Pedro de Atacama in Chile and Tupiza in Bolivia are also common starting points for longer tours of the Salar de Uyuni and the surrounding attractions.

Salar de Uyuni is the world's largest salt flat
Salar de Uyuni, or "Salar de Tunupa", is the world's largest salt flat, spanning an area of 10,582 square kilometres (4,086 square miles) in the Daniel Campos Province in Potosí in southwest Bolivia. The elevation of the salt flat is 3,656 metres (11,995 feet) above sea level, near the crest of the Andes mountains.
The Salar de Uyuni was formed as a result of transformations between several prehistoric lakes that existed around forty thousand years ago and eventually evaporated. Today, it is covered by a few metres of salt crust, which has an exceptionally flat surface with average elevation variations of within one metre over the entire area. This flatness, along with the large area and clear skies, makes the Salar ideal for calibrating the altimeters of Earth observation satellites.
During the rainy season, from December to April, a thin layer of water transforms the salt flat into the world's largest mirror, spanning 129 kilometres (80 miles) across. This natural phenomenon creates a stunning reflection of the sky, attracting tourists and photographers alike. The rainy season is also when the Salar serves as a breeding ground for three South American species of flamingos: the Chilean, Andean, and rare James's flamingos.
The dry season, from May to November, presents a different landscape. The ground hardens, and polygonal patterns of salt rise from the ground. The dry season is also when the Salar becomes a major transport route across the Bolivian Altiplano, as vehicles can drive across the vast, stark white landscape.
The Salar de Uyuni is not just a natural wonder but also a lucrative extraction site for salt and lithium, an essential element for powering laptops, smartphones, and electric cars. The vast landscape also served as a filming location for movies such as "Star Wars: The Last Jedi" and "The Fall".
The unique beauty of the Salar de Uyuni, with its vast expanse of salt and otherworldly terrain, makes it a popular tourist destination. Visitors can choose from various tour options, including shared and private tours, originating from Uyuni, San Pedro de Atacama, or Tupiza. The town of Uyuni, packed with tourism agencies, is the most popular jumping-off point for tours of the salt flats.

It is located in the Daniel Campos province of Bolivia
The Salar de Uyuni, or "Salar de Tunupa", is located in the Daniel Campos province of Bolivia. It is the world's largest salt flat, spanning an area of 10,582 square kilometres (4,086 square miles) and sitting at an elevation of 3,656 metres (11,995 feet) above sea level. This elevation means that visitors to the salt flats may experience altitude sickness, with potential symptoms including nausea, headaches, and insomnia. The best time to visit the Salar de Uyuni is during the transition from the wet to dry season in May, when there is a good chance of seeing the salt flats in both a dusty and reflective state.
The Salar de Uyuni is located near the crest of the Andes mountains and is surrounded by the Tunupa, Kusku, and Kusina mountains. According to legend, these mountains were once giants. Tunupa, an important goddess of the Aymara people, married Kusku, but he left her for Kusina, and her tears of grief mixed with her breast milk to form the Salar.
The salt flats are a popular tourist destination, attracting more than 300,000 visitors per year. The natural beauty of the region includes the unique hexagonal patterns formed by the salt, as well as the cacti-covered islands and dormant volcanoes that dot the landscape. The Salar is also a prime breeding ground for several species of flamingos and is home to around 80 species of birds.
The Salar de Uyuni is a valuable source of salt and lithium for Bolivia. The salt crust, which is up to a few metres thick, is extracted for local use and international export. The flats are estimated to contain 10 billion tonnes of salt, of which less than 25,000 tonnes are extracted annually. The lithium beneath the salt crust is also of significant value, with Bolivia holding about 22% of the world's known lithium resources, most of which are located in the Salar de Uyuni.

The flats span more than 4,000 square miles
The Salar de Uyuni (or "Salar de Tunupa") is a remarkable vista, stretching across more than 4,000 square miles of Bolivia's Altiplano plateau. It is the world's largest salt flat, formed over millennia by the transformation and evaporation of several prehistoric lakes. Today, it presents a unique and breathtaking landscape, attracting tourists and filmmakers alike.
The vast expanse of Salar de Uyuni is truly awe-inspiring, covering an area of 10,582 square kilometres (over 4,000 square miles). This immense salt flat is located in the Daniel Campos Province in Potosí, in the southwest of Bolivia, near the crest of the Andes mountains. Its elevation reaches 3,656 metres (11,995 feet) above sea level, making it one of the highest places in the country.
The formation of Salar de Uyuni is a result of the evolution of ancient lakes over tens of thousands of years. Around 30,000 to 42,000 years ago, the area was part of the vast Lake Minchin, which later transformed into Paleo Lake Tauca. Eventually, it became the youngest prehistoric lake in the region, Lake Coipasa. When Lake Coipasa dried up, it left behind two modern lakes, Poopó and Uru Uru, and two remarkable salt deserts: Salar de Coipasa and the larger Salar de Uyuni.
The salt flat is characterised by a thick crust of salt, several metres deep, that stretches as far as the eye can see. This salt crust covers a pool of brine rich in valuable minerals, particularly lithium. The flatness of the salt desert is truly extraordinary, with average elevation variations of less than one metre across the entire area. This makes it ideal for calibrating the altimeters of Earth observation satellites.
The sheer size of the Salar de Uyuni, combined with its clear skies and flat surface, creates a unique environment for satellite calibration. The large, stable surface reflects light strongly, similar to ice sheets, making it perfect for calibrating satellite distance measurement equipment. The exceptional flatness of the salt flat, maintained by seasonal flooding, ensures that the accuracy of satellite measurements is optimised.
