Khamlia is a small town of just over 400 inhabitants. Located in the southeast of Morocco, at one end of the oval that forms the dunes of the Erg Chebbi, 8 km from Merzouga. A priori it may seem like another desert town: adobe houses, mosque, Amazigh-speaking people (Berber), but it is far from resembling other towns in the area. The inhabitants of Khamlia are mostly black people of color. The soundtrack of Khamlia says good morning to the people one more day in the house of music, where the group "Pigeons du Sable" in addition to working, keeps alive with their voices a culture and history born from the bowels of suffering and humiliation of millions of men and women of black Africa in the era of slavery.

Erg Chebbi has a length of 22 km (from north to south) and 5 km wide, and its dunes have a maximum height of 150 m. Located about 40 kilometers southeast of Erfoud, the villages located at the foot of the dunes are Hassi-Labiad and Merzouga that receive most of the tourists who visit the erg. The dunes of Erg Chebbi reach a height of up to 150 meters in some places and together it extends over an area 50 kilometers from north to south and a maximum of 5 to 10 kilometers from east to west that covers the border with Algeria.
