From Ouarzazate, the N9 plunges southeast into the Draa Valley, formed by a narrow ribbon of water from the High Atlas that occasionally emerges triumphantly in lush oases, particularly between Agdz and Zagora, a stretch of about 95km. The drive from Agdz to Zagora takes three to four hours, though the more scenic Circuits Touristiques route follows the piste through the oasis. Beyond that, a road takes you 96km further south to M’Hamid, a town 40km short of the Algerian border that marks the end of the road and the start of the desert proper.
