The Ziz Valley and its southern expansion into the Tafilalet oasis form one of Morocco’s most historically significant and visually extraordinary landscapes — a 200-kilometre corridor of date palms following the Ziz River from the High Atlas foothills to the pre-Saharan plains approaching Merzouga. This landscape is both a geographical and a historical gateway to the Sahara Desert, and it is traversed by all desert tours departing from Fes, Errachidia, or approaching Merzouga from the north.
The Geological and Historical Significance of the Ziz Valley
The Ziz Gorges, immediately south of the town of Rich, provide the most dramatic introduction to the valley. The Ziz River has cut a spectacular canyon through the Saharan Atlas limestone plateau — walls of cream and ochre rock descending vertically to the river below, with the road carved into the cliff face providing views over a canyon scale that surprises travellers who have no knowledge of its existence. The gorges extend for approximately 15 kilometres before the valley opens into the broader Tafilalet oasis floor.
The Tafilalet: Morocco’s Largest Oasis
The Tafilalet palm oasis is Morocco’s largest — a network of date palm groves, irrigation channels, and oasis villages that once sustained one of the most important cities in West Africa. The ancient city of Sijilmassa, founded in approximately 757 AD near modern Rissani, was the northern terminus of the trans-Saharan gold and salt trade for over five centuries. At its peak, Sijilmassa’s population exceeded 100,000 people — comparable to the great cities of medieval Europe — and its rulers controlled the flow of gold from the Mali Empire to Mediterranean markets. The city’s ruins, while modest compared to the grandeur they once represented, are nevertheless evocative and accessible near the modern town of Rissani.
Rissani Market: A Living Traditional Trading Town
The weekly market at Rissani (held on Sunday, Tuesday, and Thursday) is one of Morocco’s most authentic commercial gatherings — a traditional market where livestock, date varieties, traditional crafts, spices, and locally-produced goods are traded by Berber and Arab merchants from the surrounding oasis communities. The market provides an extraordinary window into the living commercial culture that has sustained the Tafilalet since Sijilmassa’s era.
The Ziz Valley and Tafilalet are central to our desert tours from Fes and Errachidia. Our 3-Day Merzouga Desert Tour from Ouarzazate to Marrakech passes through this region on day one of the journey south. Browse our home page for the full tour collection. UNESCO — Medina of Fes and UNESCO World Heritage — Ksar of Ait-Ben-Haddou provide further historical and travel context.
