Erg Chebbi, situated near the border with Algeria, is one of Morocco’s two big Saharan ergs or large sandy dune fields. Formed by wind-blown Saharan sand, the shape-shifting dunes can reach a height of up to 160 meters and cover a vast area in the middle of the Moroccan stone desert. Near the edge of the dunes is Merzouga, a small village that serves as a local tourist center with number of companies organizing sunset and sunrise trips riding dromedaries deep into the sand dunes and enjoying the stunning views of sun raising and setting behind the great orange sandy dunes. But probably the best trips are the ones taking you on the overnight stay with sleeping in Berber tents under the great dunes and great food - delightful Tajine prepared on the spot – served under the soft glow of those bright stars on vast night sky.
The Arab simply looked at us. He placed his hands firmly on our shoulders, and we obeyed him. We lay down upon the sand. There are no races here, nor any languages, nor any discord… There is this poor nomad who has placed his archangelic hands on our shoulders… All other pleasures seem trivial to those of us who have known the joy of a rescue in the Sahara.— Antoine de Saint-Exupery, (Source)
