Our pick #1
Uyuni Salt Flats
Piercing blue skies contrast with blinding white salt as you drive across the flat lakebed. The area’s unusual landscape of mountains, active volcanoes, and geysers is like nowhere on earth. Salar de Uyuni is the world's largest salt flat at over 12,000 km² and is located in southwest Bolivia. It is the remains of an ancient salt lake and is estimated to contain 10 billion tonnes of salt! At certain times of year the rain causes an icy lake to form above it, and the reflections are literally incredible to look at, especially at sunset, making it difficult to tell where sky stops and ground begins.
Another must see is nearby Laguna Colorada a large red lagoon whose color is the result of algae & plankton growth in the mineral-rich waters, and Laguna Verde a lake that owes its striking blue-green color to high concentrations of lead, sulfur, copper and other minerals. You can see numerous geysers, boiling mud pools, thermal baths and Licancabúr volcano in the area.
