During the nineteenth century, Uyuni was an important hub of transportation with plans for expanding the already-existent rail network. When those plans fell through, numerous trains and rail equipment were left in the desert to rust. What remains is known as the Train Cemetery (Cementerio de Trenes).
Hollowed out locomotive bodies from the Gilded Age sit out in the open, many heavily corroded from the salt of the nearby salt plain — the world’s largest. Visitors are free to snap photos of the train bodies, and even climb inside.
The Train Cemetery is located close to the Uyuni Salt Flats, so it’s possible to stop by on the way.
