A River That Shaped the Route South
The Ziz River rises in the High Atlas and flows southeast toward the Sahara, and for centuries the valley it carved has shaped the route between Fes and the desert oases beyond. The road today largely follows the same path traders and caravans once used, dropping out of the mountains through the Ziz Gorges — a section of tight switchbacks and tunnels blasted through rock in the 20th century — before the valley opens out into wide palm groves.
The Ziz Gorges
North of Errachidia, the road threads through the Ziz Gorges, where the valley narrows and the river cuts close beside the roadway between steep rock walls. Several viewpoints along this stretch offer a chance to stop and look back down the gorge — one of the more dramatic short sections of driving on the route between Fes and Merzouga, and a natural break in a long day on the road.
The Palm Oasis
South of the gorges, the valley widens and the Ziz oasis begins — a nearly continuous run of date palms stretching roughly 15 kilometers (about 9 miles) alongside the river, dotted with small kasbahs and villages built from the same reddish earth as the surrounding hills. It's one of the longest continuous palm oases in Morocco, and a striking sight from the road above, particularly in the late afternoon light. Dates from this region, especially around the town of Erfoud, are considered among Morocco's best.
Where the Ziz Valley Fits on the Map
The Ziz Valley sits directly on the standard route between Fes (or Midelt) and Merzouga, meaning it requires no detour to see — it's simply part of the drive south to the Sahara. Most itineraries that include a night in the Merzouga dunes pass through the valley in one direction or both, making it one of the more memorable, unplanned highlights of a Sahara-bound trip rather than a separate stop to research.
A Good Stretching Point
Given how long the drive from Fes to Merzouga can be, the Ziz Valley's viewpoints double as a natural place to stop, stretch, and take photographs partway through the journey — usually alongside a roadside café or two overlooking the gorge, where mint tea and a break from the car are easy to find.
