My husband is 6 foot 4 inches
or
1,82m tall
This is Dune 7
outside Walvis Bay
Namibia
A Sand Dune in the Namib Desert
That’s my husband climbing to the top
Dubbed by the Namibia Ministry of Environment and Tourism as the highest sand dune in the world, you need to see Dune 7 to believe it. The 1,256-foot or 383m dune got its name because it is the seventh dune past the Tsauchab River, which runs through part of the Namib Desert. The desert itself, believed to be dry for at least 55 million years, is considered the oldest in the world, so make sure you spend some time exploring it while you’re here.
