The world’s highest salt flat, the otherworldly Salar de Uyuni is an obvious draw, and best seen and appreciated by a drive across it. In the middle of the flats you will find the Isla del Pescado (Fish Island) or Incahuasi, which has great views of the vast expanse of white and the distant hills, framed by the gigantic cactus that grow here. You can’t stay here, but there is a restaurant run by the owners of Mongo’s in La Paz.
This trip is enough in itself, but many people combine it with (and most tours include) a visit to the grotto Galaxy Cave, formed by the explosion of hot lava into a freezing lake, and a detour down to the Laguna Colorada (Red Lake) and Laguna Verde (Green Lake) close to the Chilean border. It’s well worth it. The two lakes, in the Eduardo Aboroa Reserve, are a haven for birds, and provide some of the most striking scenery in Bolivia. Get there in the afternoon for the full, colorful effect.
