The Dune de Pyla or Pilat, is the tallest dune in Europe. We climbed up the slippery plastic stairs to the top of the dune, then walked along the ridge to get a better view. The view was spectacular in all directions. I have never been to the desert, but I imagine it could look something like the Dune de Pyla, minus, of course, the Atlantic on one side and the forest on the other.
