Experience to live it and not to describe it. In my case they took us by 4x4 from Erfoud to the foot of the Erg Chebbi desert, to ride dromedaries that left us in the dunes until sunset. It is spectacular to contemplate the sunset surrounded by dunes of more than 150 meters high of that reddish sand. Additionally with this excursion, to complete the experience you could choose to spend the night in tents, tents for 2 or three people where you are unbearably hot and perhaps cold in winter. An experience to disconnect, reflect and take impressive photos of the desert. A mandatory excursion if you travel here. It is recommended to bring water and a scarf to protect yourself from the sun and sand if you are going to go at times when the sun is high. Totally recommended for families, couples and groups of friends.
