The massive Bolivian salt flats become accessible for walking and biking when they get dryer. You get the chance to explore many beautiful areas located within the flat, namely islands, that are inaccessible during other times. The dry season is beneficial for true adventurers. Between May and October, the water dries up so you can rent a 4x4 car or take a guided tour to move across the famous Salina de Uyuni, as well as find a dry patch for a break or a camp. Salt flats are incredibly beautiful at any season even without the mirror-like effect that can be observed during the wet season.
