The isolated landscape, which was formed when prehistoric lakes dried up to leave layers of salt, is a jaw-dropping sight. The flat surfaces stretch as far as the eye can see, made all the whiter by endless expanses of bright blue sky.
Booking your tour
Tours can be booked through La Paz, Uyuni or Tupiza and cost around 250bs (£22) for one day. A three-day tour costs from 750bs (£66) and includes 2 nights accommodation, transport in a 6-person jeep and food.
As well as the salt flats, you’ll see active volcanoes, eye-popping lagoons (including Laguna Colorada and Laguna Verde) and the stunning Desierto de Siloli.
You’ll end the tour with a trip to Sol de Manana (pictured above) to observe the geyser basin at sunrise – a strangely eery sight that is like nowhere else on earth.
TOP TIP Pack warm clothes! The salt flats are perched 3653m above sea level and temperatures plumet to below freezing at night.
