Piste de l’Erg Chebbi — Merzouga to Erg Chebbi Summit via the Grand Erg Oriental Dune Corridor
150-metre dunes, orange sand, zero mercy for flat tyres.
Erg Chebbi near Merzouga is one of the Sahara’s legitimate sand seas: a 22-kilometre-long, 5-kilometre-wide dune field that tops out at around 150 metres. The route from Merzouga village pushes northeast into the erg via sandy pistes that flank the dune base, with options to push into the interior toward the bivouac zones near Khamlia and the black dunes formed by Gnawa settlement. The sand here is classic orange-red, fine-grained Saharan erg material — the kind that collapses under you if your pressure isn’t dialled in and you hesitate at the crest of a slip face. The standard circuit loops around the northern erg edge, passes the salt lake of Dayet Srji in winter flood season, and returns via the southern hamada track toward M’Hamid direction.
Difficulty ranges from moderate (base piste circuit, well-driven, aired-down) to expert (interior dune navigation without a guide). A 4WD with low-range is mandatory; sand plates, a traction board set, and a hi-lift are not optional if you’re going solo. Tyre pressure down to 12-15 PSI for sand travel. Best season November through March — summer temperatures exceed 48°C and are dangerous. No permit required. Fuel and water in Merzouga before entry. A Sahrawi guide from Merzouga is worth the money for dune interior routes. Sleeping in the erg under a sky with zero light pollution is the whole point.

Frequently asked questions
Can a stock Jeep Wrangler or Land Cruiser handle this route without modifications?
Stock is fine if it has 4WD low-range and you air down to 15-18 PSI on sand tyres before hitting the dunes. Mud-terrain or all-terrain tyres are borderline — dedicated sand tyres make a real difference on 150-metre dune faces. Bring a compressor; you'll need to reinflate on the gravel sections.
What months should I avoid and why?
April through October is brutal — daytime temps regularly hit 45°C (113°F) and dune sand gets hot enough to cause tyre damage and overheating. Sandstorms peak in spring. Stick to November through March; nights will be cold (near freezing), but the trail is actually driveable.
Do I need a permit to drive into Erg Chebbi and camp on the dunes?
No formal permit is required for vehicle access or dispersed camping on the dunes as of 2024, but the HCEFLCD oversees the area and regulations can shift. Check with local authorities in Merzouga before departure — some access tracks near protected zones have had temporary restrictions.
What's the hardest section and what makes it dangerous?
The approach to the summit ridge via the Grand Erg Oriental corridor is where rigs get buried — steep slip-faces with soft, unconsolidated sand and no solid base to recover from if you lose momentum. If you crest wrong or stall on a 30-degree face, you're digging and using boards. Run it with a second vehicle if possible.
How far is the nearest fuel and how much range do I need?
Merzouga is your last reliable fuel stop — there's a station on the main N13 road. The route is 56 km but expect heavy fuel consumption in low-range sand driving; budget for at least 2-3x your normal burn rate. Carry a minimum 20-litre jerry can, and don't count on refueling anything between Merzouga and your turnaround point.
