Uyuni: Gateway to Bolivia’s Vast Salt Flats
Uyuni, a high-altitude town in southwest Bolivia, stands as the principal entryway to the surreal expanse of the Salar de Uyuni—the world’s largest salt flat. Despite its remote, cold, and bare location, Uyuni pulses with vibrant activity thanks to its steady flow of international and local travelers, all eager to set out on unforgettable journeys across an extraordinary landscape shaped by nature, history, and myth.
Introduction to Uyuni
Surrounded by an uncompromising, desert-like plateau, Uyuni might seem unassuming to first-time visitors. Yet, its strategic location at 3,656 meters (11,995 feet) above sea level makes it the beating heart for tour departures to the Salar de Uyuni and the wider Southwest Circuit of Bolivia. The town itself experiences fiercely cold winters—local Bolivians often refer to the area with a whistle and the words harto frío (extremely cold). Nevertheless, Uyuni retains a cheerful energy, hosting adventurers who seek to explore some of South America’s most spectacular natural wonders.

The Legendary Salar de Uyuni
The Salar de Uyuni, spanning more than 12,000 square kilometers (over 4,600 square miles), sits at 3,653 meters (11,984 feet) and forms a glimmering sea of gleaming salt crust. This landscape originated from the prehistoric Lake Minchín, which dried millennia ago, leaving behind vast mineral-rich flats. It is now one of the most iconic destinations in South America, known for its blindingly bright salt, endless horizons, and mirror-like surfaces after seasonal rains.

Cementerio de Trenes (Train Cemetery)
Just outside town, the atmospheric Train Cemetery consists of dozens of rusted steam locomotives and train cars, relics of Uyuni’s heyday as a mining and transport hub in the late 19th and early 20th centuries. It’s an open-air graveyard for these majestic machines, now a top spot for evocative photography and exploration.
