I arranged for Uyuni to wait for 5 days for the best weather of the sky mirror. It was really a poor life to report a three-day, two-night tour. The tour guide and driver were locals, only speak Spanish and very limited. In English, we started this Spanish group with a guess. After passing the train cemetery and the Uyuni salt flats, you will pass through the cactus island. By the way, you can see the salt hotel for a long time. However, it is too lazy to be photographed. It should be called The Valley of Rocks. Although it is an attraction, there is actually no original ecological driving. There is no place to replenish it all the way.
