Train Graveyard

Near world's second largest silver mine, at this historical site there's the Bolivia's first railway and a train robbed by Butch Cassidy and the Sundance Kid.

A salt processing village, 7 km north of Uyuni. Lots of salt souvenirs available for purchase, and there's a small museum of salt statues.

Area with many salt piles, weighing approximately a ton each, which are left there to dry.

A town nearby the homonymous mine, one of the largest mine facilities in Bolivia. The town used to be near the mine, but was completely moved to this area. There was a 350-year-old church in the city; it was not destroyed, but instead transported and rebuilt stone-by-stone at the new spot, including the cemetery. The altar within is made of silver, likely because the mine is 3rd largest silver producer of the world.

The "island" of fossilized coral, covered in ancient cacti that grow only a centimeter a year. It's not an island in the strictest sense, just a big rock sticking up out of the otherwise flat ground, but the salt near the edge of it looks strikingly like water coming up to the shore. The island has a hiking trail to the top, for truly surreal views of the salar. It also has a restaurant, and lunch is eaten by most tour groups on the western "shore" of this island. There are well-maintained washrooms.

A dormant volcano that some longer tours allow you to hike up. At some times of year you can see flamingos eating microorganisms at the foot of the volcano.
