We arrived in Uyuni after a night bus from La Paz and went straight to a 3 days tour in a 4wd vehicle. We drove on the Dakar race tracks, through an impressive salt lake. We took a couple of funny pictures with the rest of our group (a young couple from London, 3 German-Switz, a Brasilian couple of retired people and an English-Brasilian couple). There is randomly a cactus island right in the middle of the salt lake! Next day we saw lagoons and volcanos and a lot of flamingos, of a specific race that can cope with the 4,000m altitude. We also had a brilliant stars-watching experience, as there are a very few clouds at that altitude and the closest village was 50km away! Last day we saw impressive geysers, which are quite smelly, a hot spring where we had a lovely bath in it and a couple of other lagoons before crossing border with Chile.
