The dunes of Erg Chebbi is a strikingly strange natural formation. On the top of the flattest area you could imagine, suddenly a long mountain of sand rises. This mountain is surrounded by flat and desolate nature on all sides, and you could end up wondering if it really is real. But so it is, even if its existence is so weird that it has given rise to lengeds and myths among the locals. One legend tells us that the dunes of Erg Chebbi were created by God as a punishment to the locals of nearby Merzouga after they refused to give shelter to a woman and her child during a local festival. A sandstorm came, and buried the village of Merzouga is it was then.
