Rissani is the last village on the Ziz River before the vast desert begins. Most of the inhabitants still live in the 18th century ksar, a maze of dark passages. There are small canals running between the heavily populated villages of Rissani. Five minutes walk west of Rissani lies the ruins of the first Arab and Islamic city of Morocco. Well worth visiting is the kasbah of Oulad Abdelhalim, a magnificent imperial building. The marketplace is also an exciting place to visit, where desert dwelling Moroccans come to buy and sell.
