The dunes at Sossusvlei are numbered based on their distance from the entrance gate. This is “Dune 40”. Dune 45 is the most famous, and many people stopped and asked us if this was Dune 45 when were shooting photos. Once they found out that it was not, they moved on, leaving this amazing view to us alone. Sometimes it pays to trust your eyes and leave the guide book on the dash.
