The best full day option in Uyuni! Visit the Train Cemetery, Colchani Village, watch the salt process and visit the blocks and salt hills. You're also going to have a very nice lunch right in the middle of the salt flat. Visit Incahuasi Island in the middle of the Salt Flat and Pucara de Ayque at the Foothills of Thunupa Volcano. This is a private service, just for you and your party!
