Salar de Uyuni(salt flats)
I did a 4 day 3 night trip through the salt flats in southern Bolivia, the trip cost 600 Bolivianos which is around $100 US. included in the price were 3 meals per day, accommodation and an english speaking guide. what we got were 3 snacks per day, very basic accommodation and a guide who didn't speak a word of english, but we didn't really expect anything more cause thats just the way things are in Bolivia.
The tour starts in Uyuni, a small town with a few restaurants, a couple of chemists, a colourful sunday market and a ton of tour companies.
with dusty streets and buildings made of mud and straw there isn't many other reasons for being here apart from doing the salt flats tour.
