The Witsand Nature Reserve in the Northern Cape is an exceptional destination, featuring geological and climatic anomalies that cause the desert sand to “roar” loudly! It is a natural attraction and is one of the Green Kalahari’s best-kept secrets. The birding here is exceptional, and you’ll see plenty of wildlife too.
Against the rust-red sands of the Kalahari, the “roaring” white sand dunes of Witsand Nature Reserve remain a mysterious natural phenomenon.
Scientists believe, that these pale dunes had to have emerged from an isolated range of hillocks buried beneath the sand, from which springs a natural reservoir that, over millions of years, has gradually leached the red-oxide from the dunes, turning them white.
Known as Witsands’,(Whitesand) Roaring Sands or Brulsand, their countless millions of grains of sand rub together to emit a deep reverberating hum. For this natural phenomenon to occur very hot and dry conditions are necessary, so although Witsand in the Kalahari is warm all-year-round, summer is the best time to experience this extraordinary sand “music”. More of a rumble than a roar, one has to be within close proximity of the dunes to hear their unique sound.

I have never seen such beautiful sights in South Africa. The thing with the world media is that they tend to focus upon all of the negative stuff that happens in Africa in general.
It’s the first time I know this thing.
That is amazing, André! I never heard of this phenomenon.
