You can't windsurf without any wind, so we trekked around the dunes. They are far more grander and further away than it seems...trick of the eye. After walking the loooong way because I was freakin out about invisible crocodiles, Mike freaked out about a visible bull that we thought was about to charge us. We walked very quickly passed it and it's babies, looking behind us all the time to a wall of sand. It had to be 30-40 meters high, with about a 60 degree slope, so climbing it was hard because your feet slide backwards a little each step. The view from the top made it clear just how much of the place was sand dunes.
