That section from the dunes up to the high point is some of the most spectacular riding out there. Lost of HP opportunities and ridges to ride up. You can basically ride anywhere, but got to be careful because there are cliffs and boulder strewn slopes that can cut you off. I suspect they will take a route past a little mine called Tatasi. I would love to set routes for the Dakar in Bolivia. This little jaunt around the Salar is not exactly creative. There are a lot more technical and interesting places they could have gone to in a loop from Uyuni too.
