That was brutally cool and a lot of fun. But you had to be very careful because, like in the snow, it was very difficult to see the contours and huge ravines could suddenly appear in front of you. It's so sad that there isn't something like this in Germany, I can really recommend it to everyone to do it. It is so impressive how huge these sand dunes are. It's super difficult to orientate yourself and find your way back to the starting point.
