The impressive sand dunes at Sossusvlei offer the world's largest (and most spectacularly colored) sand box to play in. While the sea is a little chilly there's a perfect swimming beach for children in Swakopmund. World class safari parks like Etosha offer family-friendly lodging and there are also opportunities to learn how to hunt with San Bushmen or play with the Himba.
