Going to be in Chile mid-April till early May, and more-or-less given up on the idea of seeing Salar di Uyuni on a trip from San Pedro (because of time, and the difficulty of finding a reliable tour company whose drivers don't get drunk or have fatal collisions...). We are considering seeing Salar Coipasa instead, but the only accommodation option seems to be Hotel Isluga in Colchane. Trying to get information on local guides(?), and whether Salar de Urire is a realistic day-trip from Colchane. What are the roads like? (would be in a rented 4wd) The web seems to be pretty much a black hole on this area of Chile/Bolivia. Any advice welcome!
