The highway running through the dried Salar de Uyuni is located at an altitude of 3,650 m (11,811 ft) above sea level. Local landscapes are so unusual that it’s easy to get lost in them, and cell phones here are mostly useless. Even though it’s safe to go here with a tour group, it’s better to avoid going on your own, especially since at night the temperature falls to −30°C (-22°F).
