Walking on the Sand Dune

I have walked on desert sand dunes but never on sand dunes as high as the one I am going to show.

My wife and others have been trekking on some of the tallest sand dunes in Namibia, Africa.

As they climbed up the sand dunes along the crest line, the wind was howling.

That was the quickest way to get to the highest point of the dune.
