This is the backside of Dune 7 in Namibia. You can rent quad bikes here, or go sand dune boarding. We decided that rather than do either of these activities we’d take our own 4×4 into the off-road area. It took us about 3 minutes to get stuck on the side of the dune. Thankfully we were able to push it free after digging out the sand around the wheels. After this we stuck to the hard sand until parking it and setting off up the dunes on foot.
