Piste de l’Erg Chech — Tindouf to Bordj Badji Mokhtar via the Erg Chech Sand Sea
The Sahara's emptiest sand sea crossing.
The Erg Chech is not a trail in any conventional sense — it is a 500-kilometre corridor of raw Saharan desert linking Tindouf in far southwestern Algeria to Bordj Badji Mokhtar near the Mali border, threading through one of the emptiest sand seas on Earth. There are no waypoints, no signage, no tracks older than the last windstorm. Navigation is by GPS and sun compass. The sand here runs deep and soft in the interdune corridors, punctuated by rocky reg flats that offer brief, deceptive respite. Meteorite hunters have long known this area — the region has yielded significant falls, including the Erg Chech 002 meteorite, an achondrite older than Earth. That backstory doesn’t make the crossings easier.
This is a multi-vehicle expedition-only route requiring heavily modified long-range 4WDs — full sand kit, dual spare tyres, minimum 600 km fuel range per vehicle, and satellite communication are non-negotiable. No fuel, no water, no assistance exists between endpoints. Best undertaken October through February when temperatures are survivable. Algeria requires a guide and military escort permits for the far southwest regions — factor in significant bureaucratic lead time. What you get is absolute silence, a sky that owns you at night, and a crossing fewer people complete per year than summit Everest.

Frequently asked questions
What kind of vehicle do you actually need for the Erg Chech crossing — can a lifted pickup pull this off solo?
No solo vehicle should attempt this route under any circumstances. You need at least two expedition-built long-range 4WDs with full sand recovery gear, dual spare tires, and a minimum 500-mile fuel range — there are zero resupply points between Tindouf and Bordj Badji Mokhtar. Factory lift and all-terrains are not enough; high-flotation sand tires and a rear locker are non-negotiable in the soft dune fields of the Erg Chech.
What months is the Erg Chech actually passable, and what happens if you go in summer?
October through February is the only realistic window. Summer temperatures in this part of the Algerian Sahara regularly exceed 50°C (122°F), which makes mechanical failure and heat casualties a near-certainty; sand also gets softer and more treacherous. Even in the optimal season, nighttime temperatures can drop below freezing at elevation.
Do you need a permit to drive through the Erg Chech, and how does the military clearance work?
Yes — this entire region is a controlled military zone under the Algerian Ministry of Interior. You need a travel permit (autorisation de circuler) obtained in advance through the Algerian embassy in your home country, and you must register with the military garrison in Tindouf before departure. Expect checkpoints, escort requirements, and the possibility of being turned back without the correct documentation in hand.
What's the hardest section of the route and what should you actually expect when you hit it?
The central Erg Chech dune corridor — roughly the 150–250km stretch south of the last known piste markers — is where most expeditions get stopped or lose serious time. Dunes reach 100+ meters with no defined track; navigation is entirely by GPS waypoints and compass, and a single soft-sand bog can take hours to recover with multiple vehicles. Plan for 30–50km days in the worst sections.
How much water and fuel do you realistically need to carry for the full 547km route?
Carry a minimum of 300 liters of fuel per vehicle — more if you're running heavy loads or towing — because there is absolutely no fuel between Tindouf and Bordj Badji Mokhtar. Water minimum is 15 liters per person per day for a worst-case 12-day crossing, plus emergency reserve; a mechanical breakdown with inadequate water is a fatal scenario out here.
