Ait Ourir is a small Berber town on the main road between Marrakesh and Ouarzazate, about 40 kilometres southeast of Marrakesh, just before the road begins its climb toward the Tizi n'Tichka pass. Most travellers pass through without stopping, but the town's Tuesday souk is one of the liveliest in the region and worth timing a visit around if you can.
The Oued Zat valley runs through town. For much of the year it's reduced to a trickle, but the riverbed and its smooth stones are pleasant to walk. The valley between here and the High Atlas is good amethyst country — local vendors sell rough crystals.
