How to Get There
The Journey to Salar de Uyuni
Getting to Salar de Uyuni may seem like a daunting task, but it’s an adventure in itself that adds to the allure of the destination. Most travelers begin their journey in Bolivia’s capital, La Paz, or in Chile’s Atacama Desert, from where several travel routes lead to the salt flats. Although remote, reaching Salar de Uyuni is surprisingly accessible if you plan ahead.
- From La Paz:
- The most direct way to reach Salar de Uyuni is by flying from La Paz to the small town of Uyuni. The flight takes about an hour, and there are daily flights operated by local airlines such as Amaszonas and Boliviana de Aviación.
- Alternatively, for the more adventurous traveler, an overnight bus from La Paz to Uyuni is a budget-friendly option. The ride takes around 10-12 hours, and buses are equipped with reclining seats for overnight comfort.
- From Chile (San Pedro de Atacama):
- Travelers coming from Chile often choose to embark on a multi-day jeep tour that crosses the border and explores the stunning landscapes of both the Atacama Desert and Salar de Uyuni. This option includes several natural highlights along the way, including geysers, hot springs, and colorful lagoons.
- From Other Bolivian Cities:
- For those exploring Bolivia more extensively, buses are available from cities such as Sucre and Potosí, with journey times ranging from 6 to 8 hours.
Once you arrive in the town of Uyuni, the adventure truly begins. Most travelers opt for a guided tour, either a one-day excursion or a multi-day journey that ventures deeper into the wilderness surrounding the salt flats. These tours typically include transport in 4×4 vehicles, knowledgeable local guides, and plenty of opportunities to explore the region’s natural wonders.

Things to Do at Salar de Uyuni
Unforgettable Adventures Await
Salar de Uyuni offers more than just a visual spectacle; it’s a playground for adventurers, photographers, and nature lovers alike. Whether you’re here for a day or several, there are countless ways to experience the magic of the salt flats and the surrounding region.
- Explore the Salt Flats: The main attraction is, of course, the salt flat itself. Most guided tours take visitors to key points of interest, including the eerie salt mounds that dot the landscape, the expansive fields of pure white salt, and the Ojos del Salar, natural springs where water bubbles up from beneath the surface. During the rainy season, you’ll also experience the iconic mirror effect — a once-in-a-lifetime sight.
- Isla Incahuasi: Located in the middle of the salt flat, Isla Incahuasi is an island of giant cacti and ancient coral formations, offering panoramic views of the endless white landscape. Hiking to the top of this island gives you an incredible vantage point from which to appreciate the vastness of Salar de Uyuni. The contrast between the dry, desert-like island and the stark whiteness of the salt flats is truly remarkable.
- The Train Graveyard: Just outside the town of Uyuni, you’ll find the Cementerio de Trenes, a hauntingly beautiful collection of rusting locomotives and train cars abandoned in the early 20th century. This ghostly train graveyard is a popular stop on most tours and provides a striking contrast to the pristine salt flats. It’s also a great spot for photographers looking for unique and dramatic shots.
- Laguna Colorada and Laguna Verde: For those embarking on a multi-day tour, Salar de Uyuni is just the beginning. South of the salt flats lies Eduardo Avaroa Andean Fauna National Reserve, home to stunning high-altitude lakes such as Laguna Colorada and Laguna Verde. These vibrant, mineral-rich lakes are known for their unusual colors — Laguna Colorada’s red hue comes from algae and plankton, while Laguna Verde’s green tint is due to its high copper content. Both are surrounded by towering volcanoes and are home to flocks of pink flamingos.
- Stay in a Salt Hotel: For a truly unique accommodation experience, why not spend a night in a hotel made entirely of salt? Several hotels in the area, including the Palacio de Sal and the Hotel de Sal Luna Salada, are constructed from salt blocks and offer a cozy, one-of-a-kind stay. Imagine sleeping on a bed made of salt while gazing out at the endless expanse of the salt flats — it’s an experience you won’t soon forget.
What Makes Salar de Uyuni Special?
The Unparalleled Beauty and Surrealism
Salar de Uyuni is not just special — it’s otherworldly. The sheer size of the salt flats, coupled with the vast emptiness that surrounds them, creates a sense of awe that is difficult to describe. Here are just a few reasons why this place stands out as one of the most unique landscapes on Earth:
- The Largest Salt Flat on Earth: Salar de Uyuni covers more than 10,000 square kilometers, making it the largest salt flat in the world. This immense expanse of blindingly white salt extends as far as the eye can see, and during the rainy season, the thin layer of water that collects on the surface creates a perfect mirror effect, making the horizon disappear and the sky seem infinite. This natural phenomenon is often referred to as the “world’s largest mirror.”
- A Geographical Marvel: Formed by the evaporation of prehistoric lakes, Salar de Uyuni is a unique geological formation. The salt flat sits at an elevation of over 3,600 meters (11,800 feet) above sea level and contains an estimated 10 billion tons of salt. Beneath the surface lies the world’s largest reserve of lithium, a valuable mineral used in the production of batteries.
- Otherworldly Reflections: The most famous images of Salar de Uyuni come from the rainy season (December to April), when a thin layer of water turns the salt flat into a massive mirror, reflecting the sky and creating a truly surreal visual effect. Visitors often capture incredible photos where the distinction between earth and sky vanishes, leaving behind an ethereal landscape that feels like walking on clouds.
- Endless Horizons and Optical Illusions: The vastness of the salt flat also lends itself to playful photography. With no reference points for scale, visitors can create mind-bending optical illusions by playing with perspective. Imagine photos where you’re holding your friends in the palm of your hand, or standing next to a toy dinosaur that appears life-sized — the possibilities are endless!
