What time do salt flats tours start?

Salt flats tours in Uyuni usually start "approximately" 10.00 am to 11 am but this can vary. The reasons it can vary, apart from punctuality not being very common in Bolivia, can be for a number of different things. For example there is only one fuel station in Uyuni and it can be hard to get fuel quickly so drivers might have to queue for long periods to get fuel and this can affect preparations.

We usually request you to be at the local office at 9 AM to do your check-in, but if for example if your flight lands at 9 AM then no problem simply take a taxi to the office and be there as soon as you can - we will let the office now about your flight time and this will be taken into consideration. Also buses or flights arriving to Uyuni late (more common in Rainy season) can affect departure times - if someone in your assigned group is on transport that is late then the operator will try to wait as long as is possible to accomodate that so they can get on the tour that day - obviously there are limits to this and they dont want to wait too much as it effects the rest of the groups tour time. Tours starting in San Pedro usually start earlier around 8-8.30 am.
