Very nice place, wonderful view! If you go on a tour starting from Uyuni, here is an advice: be very careful when picking the tour operator (ask about the number of persons in the group, the quantity of water and food, ask if vegetables and fruits are included in the meals,...) and be sure everything is written on your receipt or contract. From my experience, don't go with Thiago tour or with Cristal tour, they make groups of 7 persons (the cars are adapted for 6, the dormitories for the last night only have 6 beds!) while most other tour operators don't take more than 6 people per group. If you have time, start the tour from Tupiza, we heard that the tour organizers are more serious there!
