Piste de l’Erg Chebbi Sud — Merzouga to M’Hamid via the Saharan Dune Corridor and Draa Valley
Real Sahara. No tourist camps past this point.
This roughly 400-kilometre route through Morocco’s deep south is one of the most demanding and rewarding desert drives in North Africa. Starting from Merzouga — where the Erg Chebbi dunes pile up to 150 metres — the piste winds through the hammada gravel plains, skirts the foothills of the Anti-Atlas, and eventually crosses the broad Draa Valley before reaching the remote sand-sea of Erg Chegaga and dropping into M’Hamid. Key waypoints include Taouz, the border garrison town of Bir Anzarane approach tracks, and the isolated nomadic camps of the Chegaga plateau. Sand ladders earn their place in the rack on this one.
This is legitimate expedition territory — not a day trip from Marrakech. You need a capable 4WD with a snorkel (fine dust and occasional deep sand), a full navigation kit including offline maps and GPS (tracks split constantly and signage is nonexistent), and a minimum 200-litre fuel range. Guides from Merzouga or M’Hamid are strongly recommended for first-timers; the wind erases tracks overnight. October through March is the window — summer heat here kills equipment and people. The payoff is camping under the Sahara’s actual sky, far from any generator-powered tourist camp.

Frequently asked questions
Can a stock Land Cruiser or Defender handle this route, or does it need to be built out?
Stock high-clearance 4WD is not enough here. You need a properly expedition-spec'd vehicle with a snorkel, locked diffs or a locking rear at minimum, reinforced sidewall tires, and a full sand recovery kit — boards, traction mats, hi-lift, and a compressor. Soft sand sections in Erg Chegaga will swallow an unprepared rig.
What months should I avoid, and what happens if I attempt this in summer?
June through September is genuinely dangerous — ground temps in the erg exceed 70°C (158°F) and the risk of heat stroke is real, not theoretical. Tires blister, fuel vaporizes in lines, and rescue is not coming fast. Stick to October through March.
Do I need permits or do I have to register with anyone before driving this piste?
There are no formal trail permits, but you are legally required to register your route and vehicle details with the Gendarmerie Royale at checkpoints in Merzouga before heading out. They will record your passport, vehicle plate, and intended itinerary — this is not optional and they do check. Carry your vehicle registration and passport at all times.
What is the hardest section of this route and what exactly makes it technical?
The Erg Chegaga crossing south of Foum Agoutir is where most teams have serious problems — sustained deep soft sand dunes with no defined piste, zero shade, and zero margin for navigation error. Dunes shift seasonally so tracks from a previous trip may be completely gone. You need to be comfortable driving by compass and GPS simultaneously while reading sand texture in real time.
How far apart are fuel stops, and can I make it on a standard tank?
Fuel is available in Merzouga at the start and in M'Hamid at the end — there is nothing reliable in between across the full 400km. A standard 70–80L tank will not cut it. You need a minimum 150L total fuel capacity between your main tank and jerry cans to complete this route without gambling on finding diesel in small settlements along the Draa valley, which are inconsistent.
