The big desert plateau of the Hamada of Kem Kem; opens up on to the wonderful world of dunes and ergs: Erg chebbi dunes until the erg Znigui and erg Ouzina. On a three-day trip along the southern border, the desert assumes its full dimension, from one erg to the next, in the direction of the Azerkam Oasis and the saf saf oasis. The three-day tour is held in a remote location. The magic of the desert is then completely understood here, beneath the stars, in the vast Saharan quiet.
