If you're in good shape, you can hike to the top of Big Daddy, the highest sand dune in the world at 360 meters (1,181 feet). But it's tough going: more than an hour of very hot trudging and wading through ankle- and sometimes knee-deep sand to climb the major route up to Dead Vlei (where ghostly skeletons of ancient trees jut up from a flat, sandy, dried-up lake) and Big Daddy (the hub of Sossusvlei) from the parking area. If you don't feel up to any physical exertion
at all, then sit in the shade of camelthorn trees at the bottom of the dunes and watch the birdlife, or focus your binoculars on the distant climbers.
