A:
Due to travelling time from La Paz to Sajama one day is not enough to visit Sajama and also I don't think so that there is a one day tour to Sajama. Usually the tours that departure from La Paz are two days tour. When I went to Sajama I went by myself. I took a minibus in La Paz Central Cemetery to Patacamay (8 B$) and then a van from Patacamaya to Sajama (30 B$). I stayed at Hotel Sajama, (120 B$ room for 2 people with private bathroom and breakfast included. There aren't lunch just dinner @ 30 B$). Any way, before my trip when I was searching information regarding Sajama I found two Bolivian travel agencies that has 2 days tour to Sajama. I don't know how much it cost however it should not be cheap because they are private tours. 1- BoliviaMia - Lodge at Tomarapi Eco Lodge (expensive hotel) 2- TourismoBoliviaPeru - Lodge at family house. Cheers and have a nice trip.
