We will be in SPA for three days this coming March (arrival in the morning and departure in the AM three days later). We will then travel via a 4WD tour through the Bolivia Altipano and Salt Flats to Uyuni. Question is, what days trips should we do in SPA and which ones can we miss as the tour to Uyuni would be similar and thus make these portions redundent? Currently, we would plan on visiting the highlights close to town (Valle de la Luna, Valle de la Muerte and Quebrada del Diablo), possibly the ruins at Pucara de Quitor, and to do the Star Observation one night. Things we are not sure of include Laguna Tebinquinche and Salar de Tara. We plan on missing the the Tatio Guysers and Laguna Cejar. Any comments?
