Erg Chegaga is Morocco’s largest and, many would argue, most spectacular dune field — a roughly 40km² sea of sand with dunes reaching up to 300 metres, tucked into the far south near M’Hamid El Ghizlane.
What Is Erg Chegaga?
Despite its scale, it is not lifeless. Hardy plants such as Alfa grass, Calotropis procera, acacia and tamarisk survive along its edges, alongside seasonal wild arugula. Dromedaries and fennec foxes are common; gazelles are seen occasionally, and snakes or scorpions rarely. Berber nomad families still live and move through this landscape today, much as they always have.
Why Choose Erg Chigaga Over Merzouga?
Merzouga’s Erg Chebbi is more famous and easier to reach, which also means it draws far larger crowds. Erg Chegaga, reached via M’Hamid rather than Merzouga, offers a quieter, more authentic experience — darker skies for stargazing, fewer other camps in sight, and food that still leans on traditional nomad cooking: couscous, tajine, fresh fruit and mint tea around the fire.
A Night to Remember
If your visit lines up with late October, you may catch the Festival Taragalte in M’Hamid, or the wider Festival International des Nomades — both well worth building a trip around.
Activities
Beyond camel trekking (méharée), options include 4×4 excursions, quad or buggy rides, sandboarding down the tallest dunes, night photography, and visits to local artisans working in carpets, pottery and jewellery, as well as nearby kasbahs.
Practical Tips
The best windows are September–November and March–May. Pack layers for cold desert nights, sun protection for hot days, and comfortable closed shoes. And if you want a guide who genuinely knows this erg, ask for Yahya — he has been leading trips through it for most of his life.
