It is the point where the road journey through southern Morocco leads into the open sand. The scale of Erg Chebbi is genuinely different from the smaller dune areas near the main roads.
Erg Chebbi and Erg Chigaga are not interchangeable names. Erg Chebbi lies beside Merzouga and the paved road reaches the village; Erg Chigaga is in another part of the south near Zagora and requires a different approach. Choose according to the whole route, not a claim that one desert is better.
We can include Merzouga in one of our Morocco tours or prepare a custom trip with your dates and pace.
