Le Sahara (en arabe : الصحراء الكبرى al-Ṣaḥrāʾ al-Kubrā, “le Grand Désert”, en berbère : ⵜⵉⵏⵉⵔⵉ Tiniri) is the biggest hot desert of the world, extending over 5 000 km, from the Atlantic Ocean to the Red Sea, and covering more than 8 million square kilometers. It extends over the territory of ten States: Mali, Mauritania, Niger, Chad, Sudan, Algeria, Tunisia, Morocco, Libya, and Egypt, as well as on the controversial territory of the Western Sahara.
Contrary to a wide-spread idea, the desert of sand covers only 20 % of the surface of Sahara. Most of the travelers know the images of the deserts of sand as the Big Oriental Erg and the Big Western Erg, but ignore those of the mountains as Hoggar, Tassili, Tibesti, hamadas, and regs as Tanezrouft.
In the southeast of Morocco, in the Algerian border, the region of Merzouga is considered as its dunes, the highest of the country. A subtle and particular ecosystem governs the life of the erg and maintains the formation of its dunes which the color changes by following the course of the sun, maintaining the magnificence of this place. The humidity accumulated in a big depth allows the dunes to settle and to continue; some reach 150 m of height, the record being reached near the Algerian border. A sunset, in dunes, a fantastic experience !
