Morocco has two great sand seas. Both are genuine Sahara. Both will rearrange your sense of scale on the first morning you watch the sun clear the dune ridge. But they are not interchangeable, and choosing the wrong one for your particular trip is the kind of mistake that is difficult to recover from once you are there. This is a practical comparison of Erg Chebbi and Erg Chigaga: where they are, what they feel like, who each one suits.

The Basic Geography

Erg Chebbi sits at the edge of Merzouga, a small town in the Draa-Tafilalet region of southeastern Morocco. The erg rises abruptly from flat hamada desert floor to dunes that reach 150 metres at their highest point. The colour shifts from pale gold at midday to deep copper and violet at dawn and dusk. The dunes are continuous, uninterrupted, and large enough that a thirty-minute walk from the edge of town places you in silence.

Erg Chigaga lies roughly 60 kilometres east of M'hamid el Ghizlane, in the far south of Morocco near the Algerian border. It is smaller in total area than Erg Chebbi but considerably more remote. Access requires a 4WD vehicle or a camel trek across open desert. There is no town at its edge.

What Erg Chebbi Does Better

The dunes at Erg Chebbi are larger, more dramatic, and more consistent than at Erg Chigaga. For photography, this matters enormously. The light that falls on a 150-metre dune wall at 6am is categorically different from what you get on a 50-metre slope. The shadows are longer, the gradients steeper, the sense of scale more confrontational.

Accessibility is also a genuine advantage rather than a compromise. Because the road is paved, Erg Chebbi can be reached in a single day from Marrakech without requiring specialist vehicles. Merzouga has enough infrastructure to support private camps that maintain a high standard of comfort: real beds, proper mattresses, hot showers, and kitchens capable of cooking a serious meal. A well-run camp at Erg Chebbi does not ask you to trade quality for authenticity.

Umnya Dune Camp operates at Erg Chebbi precisely because the combination of dune scale, accessibility, and quality hosting is not replicated elsewhere in Morocco.

What Erg Chigaga Does Better

Remoteness. If what you are looking for is the experience of being genuinely far from other human beings, Erg Chigaga delivers it more completely. The piste into the erg, the absence of any permanent settlement, and the very low volume of visitors produce a silence that is qualitatively different from what you find at Merzouga, even at a private camp.

Multi-day desert expeditions by camel or 4WD make more sense originating from M'hamid and Erg Chigaga because the surrounding landscape is more varied. You move through open stony hamada, past fossilised river channels, and through fortified Berber villages before you reach the sand. For travellers whose primary goal is prolonged solitude rather than specific dune aesthetics or retreat programming, Erg Chigaga is the stronger choice.

The Question of Crowds

This question comes up often, and the honest answer requires a distinction. Merzouga itself is a small town with hotels and camps of varying quality spread along the dune edge. Certain parts of that edge do see a volume of day visitors that can undermine the sense of solitude. The solution is not to go to Erg Chigaga — it is to choose a camp positioned away from the main access corridors and to build your schedule around early mornings and late afternoons, when day visitors are absent and the dunes belong almost entirely to guests who are actually staying.

Frequently Asked Questions

Which erg is more remote? Erg Chigaga is significantly more remote. It requires a 60-kilometre 4WD drive on an unpaved piste from M'hamid, with no paved road access and minimal mobile coverage. Erg Chebbi has a paved road to the dune edge and partial mobile signal. If raw remoteness is your primary criterion, Erg Chigaga wins clearly.

Can you visit both ergs in one trip? Yes, though it requires planning. A common route combines Erg Chebbi and Erg Chigaga over seven to ten days, travelling between them via the Draa Valley. The two ergs are not close to each other — expect a full driving day between them — but the route is one of the most scenically varied in Morocco.

When is the best time to visit the Moroccan Sahara? October through April is the optimal window. Daytime temperatures in this period range from comfortable to warm, nights are cold and clear, and the light at dawn and dusk is at its most photogenic. July and August bring extreme heat with temperatures regularly exceeding 45C at both ergs.
