For most travellers, Erg Chebbi (beside Merzouga, in Morocco's southeast) is the easier and more accessible choice. A paved road runs roughly 560 km from Marrakech — about 9–10 hours over the Tizi n'Tichka pass (2,260 m) — right up to the dune edge, where you find the widest range of camps and the tallest single dunes, rising to about 150 m. Erg Chigaga (near M'Hamid El Ghizlane, in the southwest) is the remote, quieter choice: a similar total distance from Marrakech, but the final ~60 km is unpaved desert piste that takes about 2 hours in a 4x4, depending on the piste and the vehicle, with fewer camps and far fewer visitors.
So the short answer: choose Erg Chebbi for a first trip, a short schedule, or a family holiday — the smooth road and the range of accommodation make it forgiving. Choose Erg Chigaga if you want solitude, emptier horizons and a rougher, more committing adventure, and you have the extra days to reach it. Both sit in the same Moroccan pre-Sahara and share the same climate; what really separates them is how hard they are to reach and how many other people you'll share them with.
Where are Erg Chebbi and Erg Chigaga, and how far are they from Marrakech?
Both ergs lie in the Moroccan Sahara, but on different sides of the pre-desert. Erg Chebbi sits beside the village of Merzouga in the southeast, near the Algerian border, about 560 km from Marrakech via the N9 and N10 — roughly 9–10 hours by road. Erg Chigaga lies to the southwest near M'Hamid El Ghizlane, at the tail end of the Drâa Valley, a comparable total distance from Marrakech but reached on a different route through Ouarzazate and Zagora.
| From Marrakech | Approx. distance | Approx. drive time | | --- | --- | --- | | To Merzouga (Erg Chebbi) | ~560 km | ~9–10 h, all paved | | To M'Hamid (gateway to Erg Chigaga) | ~450 km | ~8–9 h to M'Hamid, paved | | M'Hamid → Erg Chigaga camps | ~60 km | about 2 h off-road 4x4 (piste- and vehicle-dependent) |
The key point is not the map distance but the last leg. Getting near Chigaga takes about as long as reaching Chebbi; getting into it takes an extra couple of hours over sand and stone. For official destination information on both regions, the Moroccan National Tourist Office is the reliable starting point.
How do you get to each erg — paved road or 4x4 piste?
This is the single biggest practical difference. Erg Chebbi is reachable by any normal car: tarmac runs all the way to Merzouga village, and the camps sit a short walk or camel ride from where the road ends. A regular rental car handles the whole journey, which is why Chebbi suits self-drivers and independent travellers.
Erg Chigaga requires a 4x4. After M'Hamid, the last ~60 km is unpaved desert piste — soft sand, rocky flats and no signposts — that takes about 2 hours (depending on piste conditions) and is not passable by an ordinary vehicle. Attempting it in a standard car risks getting stranded far from help. For that reason, Chigaga trips are almost always organised and guided: you travel with a driver who knows the piste, in a vehicle built for it.
For a first-timer weighing self-drive against an organised trip, our guide on how to get to the Sahara from Marrakech walks through both options in more detail. In short: Chebbi gives you a choice; Chigaga effectively makes it for you.
How tall and how big are the dunes at Erg Chebbi vs Erg Chigaga?
The two sand seas trade height for spread. Erg Chebbi is compact but tall — a field roughly 28 km long by 5–7 km wide, with dunes rising to about 150 m. That concentration creates a single high golden wall of sand that dominates the view above Merzouga. You can read the documented dimensions on the Erg Chebbi entry at Wikipedia.
Erg Chigaga is far larger and more spread out — a dune field roughly 35–40 km long by up to 15 km wide, but with crests that are generally lower and broader. You get more sand in every direction and fewer sharp peaks. You may see claims of "300 m" dunes at Chigaga; treat those with caution, as they are not well supported. The reliable comparison to remember is simple: Chebbi has the taller peaks, Chigaga has the wider wilderness. If a towering dune backdrop is what you picture, Chebbi delivers it; if you want an ocean of sand stretching to the horizon, Chigaga is the bigger sea.
Which erg is less crowded and feels more remote?
Erg Chigaga is clearly the quieter, more remote of the two. Because access is hard, it sees only a fraction of the visitors, which means emptier horizons and darker night skies for star-gazing. Erg Chebbi, by contrast, has decades of tourism infrastructure behind it: many auberges line its edge, camel trains criss-cross the sand, and quad-bike activity is common. At popular sunrise and sunset viewpoints it can feel busy in high season.
Neither is "better" — it's a genuine trade-off. Chebbi gives you convenience, company and amenities close at hand. Chigaga gives you isolation and silence, at the cost of a longer, rougher journey and simpler facilities. If crowds at dawn would spoil the mood for you, that alone may decide the question.
What are the desert camps like at each erg?
Camp variety follows the road. Erg Chebbi offers the widest spread of accommodation — from basic Berber bivouacs to comfortable tented camps with private bathrooms and electricity — precisely because tarmac access makes it easy to supply water, power and staff. Whatever your budget, Chebbi almost certainly has a match.
Erg Chigaga camps are simpler and more off-grid by necessity. Everything has to be carried in over the piste, so expect fewer creature comforts and a more pared-back stay — which is exactly what many travellers come for: quiet, few neighbours and an unlit night sky. On both ergs, budget group tours tend to use more basic camps, so read what's included before you book. We don't quote camp prices here because they change constantly; live prices and ratings for specific tours appear on our desert tour pages via the GetYourGuide widgets, where you can compare exactly what each option offers.
How many days do you need for each desert tour?
Erg Chebbi works well as a 3-day / 2-night round trip from Marrakech, and can even be squeezed into an intense 2-day dash, because the direct paved road makes the drive predictable. Erg Chigaga realistically needs 4 or more days to justify the longer approach and the 4x4 leg, and is often combined with the Drâa Valley, Zagora and a loop out via Foum Zguid.
A sensible skeleton for each:
Erg Chebbi — 3 days / 2 nights
- Day 1: Marrakech → Aït Ben Haddou → Ouarzazate → Dadès or Todra Gorge (overnight).
- Day 2: On to Merzouga; camel ride into Erg Chebbi; night at a desert camp.
- Day 3: Sunrise over the dunes, then the long drive back to Marrakech.
Erg Chigaga — 4+ days
- Day 1: Marrakech → Ouarzazate → Agdz, into the Drâa Valley (overnight).
- Day 2: Zagora → M'Hamid, then 4x4 over the piste to an Erg Chigaga camp.
- Day 3: Full day among the dunes; second desert night.
- Day 4: 4x4 out via Foum Zguid, returning toward Marrakech (often a further overnight).
If you want to end in a different city instead of doubling back, compare a straight-through option like the Marrakech to Fes 3-day desert route against a return loop.
When is the best time of year to visit, and how hot does it get?
Both ergs share a hot desert climate (Köppen BWh), so the timing advice is the same: spring (March–May) and autumn (October–November) are ideal, with warm days and manageable nights. Summer is harsh — around Merzouga, July daytime temperatures often exceed 40 °C and can pass 45 °C on the open sand. Winter flips the other way: January is roughly 19 °C by day but drops to about 6 °C at night, and colder still up on the dunes, where it can approach or fall below 0 °C before dawn. Britannica's overview of the Sahara sets out this pattern of scorching days and sharp night-time cooling.
The practical difference is risk. Chebbi's roadside camps and nearby villages mean help is close if the heat becomes too much; Chigaga's remoteness makes extreme summer temperatures more dangerous, since you're hours from the nearest tarmac. Whichever erg you pick, pack layers for cold nights, loose long-sleeved clothing for sun and blowing sand, and more water than you think you'll need. Our seasonal guide and packing list cover this in depth.
Erg Chebbi vs Erg Chigaga: a side-by-side summary
| Feature | Erg Chebbi (Merzouga) | Erg Chigaga (M'Hamid) | | --- | --- | --- | | Access | Paved road to the dune edge | ~60 km 4x4 piste after M'Hamid | | From Marrakech | ~560 km, ~9–10 h | Comparable, + about 2 h off-road | | Dunes | Compact, tall — up to ~150 m | Larger field, lower & broader | | Crowds | Busier, more infrastructure | Quiet, remote, dark skies | | Camps | Basic to comfortable, wide choice | Simpler, off-grid | | Minimum days | 2–3 days | 4+ days | | Best for | First trips, families, short schedules | Solitude, wilderness, adventure |
The one-line verdict: if this is your first Sahara trip or your time is tight, go to Erg Chebbi. If you've seen the desert before, want silence and space, and can spare four days for a rougher ride, go to Erg Chigaga.

Frequently asked questions
Is Erg Chigaga worth the extra travel?
It is if solitude is your priority. Chigaga trades comfort and easy access for emptier dunes and darker skies, so it rewards travellers who want wilderness over convenience — but for a first, short or family trip, Erg Chebbi usually makes more sense.
Can you drive to Erg Chebbi without a 4x4?
Yes. A paved road runs all the way to Merzouga village, and the camps sit a short walk or camel ride from where the tarmac ends, so any ordinary car can make the journey. This is a key reason Chebbi suits self-drivers.
Which desert is better for a first visit?
Erg Chebbi. Its smooth road access, tall dunes and wide range of camps make it the more forgiving introduction to the Moroccan Sahara, especially on a tight schedule or with children.
Are the dunes really taller at Erg Chebbi?
Yes — Erg Chebbi's dunes rise to about 150 m, forming a single high ridge. Erg Chigaga covers a much larger area but its crests are generally lower and broader, and claims of "300 m" dunes there are not well supported.
Can you visit both ergs in one trip?
Yes, but it takes time. Because they sit on opposite sides of the pre-Sahara and Chigaga needs a 4x4 leg, combining them realistically means a week or more; most travellers pick one erg per trip.
Is Erg Chigaga safe to visit?
Generally yes, when you go with an experienced driver and a proper 4x4. The main risks are the remoteness itself and summer heat, so travel organised, carry plenty of water, and avoid the hottest months.
