Erg Chigaga vs Erg Chebbi: size against height
Morocco's two real ergs optimise for opposite things. Neither is objectively better; they suit different travellers.
| Erg Chigaga | Erg Chebbi (Merzouga) | |
|---|---|---|
| Field size | ~40 km × 15 km | ~28 km × 5–7 km |
| Max dune height | ~60 m | ~150 m |
| Access | 4x4 only, ~2 h piste | Paved road to village |
| Camps in the field | Roughly 30 | Well over 100 |
| Visitors | Low | Very high |
| Minimum trip | 2–3 days | 3 days |
| Typical price | €200–400 | €130–200 |
| Mobile signal | None in the erg | Patchy but present |
Put plainly: Erg Chebbi gives you the taller dune and the easier logistics. Erg Chigaga gives you a horizon with nothing on it. If you have already done Merzouga and found it crowded, Chigaga is the answer to that specific complaint.
The two routes to Erg Chigaga
Both start from the Draa Valley. Most tours use the first and the more interesting ones combine both.
From M’Hamid El Ghizlane (standard). M’Hamid is the last town on the paved N9, about 450 km and 8–9 hours from Marrakech down the length of the Draa Valley. From there it is roughly 60 km and two hours of unmarked piste west to the erg, through soft sand sections that require a driver who knows the current track.
From Foum Zguid (the long way). A northwestern approach crossing the dry bed of Lake Iriki, a vast flat pan that has been dry for decades and floods only after exceptional rain. It takes longer and costs more, but it is the more spectacular drive.
The best version: in via M’Hamid and out via Foum Zguid, or the reverse. You never repeat a kilometre, you see both the Draa palm corridor and the Iriki pan, and it adds roughly half a day. Ask operators specifically whether their itinerary loops or backtracks — many quietly backtrack.
Is Erg Chigaga worth the extra cost?
It is the most expensive Moroccan desert per night and the hardest to reach. Here is the balanced case.
Why it’s worth it
- Morocco's largest dune field by a wide margin — 40 km of sand with genuine horizon-to-horizon emptiness.
- 4x4-only access filters out day-trippers entirely; you will not share a ridge at sunset.
- Some of the darkest skies in North Africa — no settlement light within 50 km.
- The approach itself is the adventure: desert piste, dry lake beds, and nomad encampments.
What to know first
- The dunes top out near 60 m — dramatic in aggregate, but Erg Chebbi has the taller individual crests.
- Costs noticeably more because the 4x4 and driver for the final leg cannot be avoided.
- No independent access. There is no bus, no taxi, and self-driving the piste is genuinely unwise.
- No mobile signal and no facilities in the erg — a medical problem out here is a serious problem.

Erg Chigaga: frequently asked questions
What is Erg Chigaga?
Erg Chigaga is the largest sand dune field in Morocco — roughly 40 km long and up to 15 km wide, with crests reaching about 60 m. It sits around 60 km west of M'Hamid El Ghizlane in the far south of the Draa Valley. Unlike Erg Chebbi at Merzouga, there is no paved road to it; reaching the dunes requires about two hours of 4x4 driving across open desert piste.
Erg Chigaga or Erg Chebbi: which is better?
They optimise for different things. Erg Chebbi has the taller dunes, around 150 m against Chigaga's 60 m, plus easy road access and far more camp choice — it is the better photograph and the easier trip. Erg Chigaga is the larger field at 40 km by 15 km and receives a fraction of the visitors, so it is the better experience of actual desert emptiness. Choose Chebbi for the dunes; choose Chigaga for the silence.
How do you get to Erg Chigaga?
Everyone stages from M'Hamid El Ghizlane, the last town on the paved N9 about 450 km and 8–9 hours from Marrakech. From M'Hamid it is roughly 60 km and two hours of 4x4 piste west to the dunes. A second, longer approach comes from Foum Zguid to the northwest, crossing the dry bed of Lake Iriki — slower but more spectacular, and often used as a one-way exit so you do not repeat the route.
Can you drive to Erg Chigaga in a normal car?
No. The route from M'Hamid is unmarked desert piste with soft sand sections, and a two-wheel-drive vehicle will get stuck. Even in a 4x4, driving it without a guide who knows the current track is a bad idea — the piste shifts, there is no signage, and there is no mobile coverage to call for help. Every visitor arrives with a driver, either as part of a tour or hired in M'Hamid.
How much does an Erg Chigaga tour cost?
Expect €200–400 per person for a 2–3 day tour from Marrakech, against €130–200 for the equivalent Merzouga trip. The premium is entirely the 4x4 and driver for the final off-road leg, which cannot be shared across a large group the way a minibus can. Booking the 4x4 and camp directly in M'Hamid, if you can get yourself there, brings the cost down substantially.
How many days do you need for Erg Chigaga?
Two days is possible but tight; three is comfortable. A 2-day version means a very long first day — around nine hours from Marrakech to M'Hamid plus two hours of piste — arriving at camp near sunset. Three days lets you break the drive in the Draa Valley or Zagora, spend a full day in the erg, and take the Foum Zguid route out across Lake Iriki instead of retracing your path.
Is there mobile signal at Erg Chigaga?
No. There is no coverage in the erg and only patchy signal around M'Hamid. Camps run on solar power with limited charging, and satellite phones are carried by some operators but not all. Tell someone your itinerary before you go, ask your operator what their emergency procedure actually is, and carry any essential medication with you rather than in a transferred bag.
When is the best time to visit Erg Chigaga?
October to April, with the same pattern as the rest of the Moroccan Sahara: 20–28 °C days and cold nights, dropping near freezing in December and January. Chigaga's remoteness sharpens the seasonal risk — a sandstorm during the February-to-April chergui winds can close the piste for a day or more, and summer heat above 45 °C makes a vehicle breakdown out here genuinely dangerous.
