We traveled across countries, from San Pedro de Atacama to Uyuni, Bolivia, I chose to report a tour group in the local area, crossing the border to Bolivia first to enter the Eduardo Abaroa Nature Reserve, then the Uyuni salt marsh, and finally arrived in Uyuni City. The whole trip 5 days 4 nights reserve is not only the location of many different plateau lakes, but also the geysers at an altitude of 4,900 meters before entering the scenic spot. You need to buy tickets, 150 Bolivian dollars. This conservation area is too big. You have to drive for several days. It is desolate to have no road at all. What I admire most along the way is to say that our young driver, if I have lost the road many times, the driver is still our chef, on the way to a picnic in the wilderness, we can see a variety of wildlife, deer, flamingos, alpacas, etc. This road, infinitely wonderful, However, the altitude is really high, generally more than 4000 meters
