The Uyuni Salt Flats were recommended to us by someone we had met in Patagonia as a must-visit in Bolivia despite how out of the way it was on the map. Taking an overnight bus, we headed to southern Bolivia, where we took a two-night, three-day tour of the salt flats and highland desert. We didn’t really know what we were getting ourselves into when we signed up for this tour, and it was certainly memorable. The first day we spent on the endless salt flats of Uyuni, the world's largest. It was fascinating learning about the rich mining history of the area, with many surrounding mountains being mineral-rich with iron, salt, zinc, copper, tin, and uranium. But the Salt Flat itself was mesmerizing as it stretched as far as you could see. When in the middle of it, it seemed as if you were sitting in the middle of a flat ocean, similar to the water scene in Interstellar. We visited some of the main attractions like cactus island and took some awesome forced perspective photos. One thing we did not anticipate on the tour was how much driving we would be doing. We spent most of the day driving in a land cruiser going from area to area, which became pretty tiring by the end. The second day we woke up early and hit the road towards the southern desert of Bolivia. Along the way, we stopped at many different spots to take photos and learn about the geography of the surrounding areas. Our guide spoke about the names of the different live volcanoes and numerous mineral lagoons that accompanied most. We drove up to above 16,000ft in elevation; it was fascinating to learn about this diverse highland landscape. The third day, we made an extended pit stop at a natural hot spring, my personal favorite part of the trip. It was even more satisfying because of how cold it was outside, 20 degrees. We made the long drive back to Uyuni where we ended our tour. Overall, it was a great but extremely tiring tour that included all the highlights of Uyuni and the surrounding volcanic desert.
