Erg Chebbi in Merzouga: Morocco’s sea of golden dunes
Published on 09/14/2026 at 17:42 | Editorial responsibility: Rafael MĂĽller, Editor-in-Chief AD HOC NEWS
Erg Chebbi is a broad field of high sand dunes on the edge of the Sahara in south-eastern Morocco, immediately east of the village of Merzouga. It forms a continuous dune sea rather than scattered hills, with sand rising sharply above the surrounding stony plain and running for many kilometres along the Algerian border.
Erg Chebbi as a Saharan dune sea
Erg Chebbi is classified as an erg, the Arabic term used in geomorphology for a large sea of wind-blown sand dunes. In this part of Morocco the dunes stand out against hamada and reg terrain, where the surface is dominated by rock and gravel rather than sand.one of Morocco’s several ergs This dune field lies in the Tafilalet region of south-eastern Morocco, close to the frontier with Algeria and within the wider Sahara Desert belt.situated in the Tafilalet
The sand forms a band of dunes that runs roughly north to south for more than 20 km, with a width of around 5–7 km from west to east. In places the difference between dune crest and surrounding plain reaches around 150 m (about 490 ft), creating steep faces that catch low-angle light at sunrise and sunset.dunes reach up to 150 m high The sand itself has a fine grain and takes on a deep orange colour under clear skies, which has made Erg Chebbi a recognisable image of the Moroccan Sahara.
Merzouga at the foot of the dunes
Merzouga is the settlement that sits immediately west of Erg Chebbi, acting as the gateway town for the dune sea. Hotels, guesthouses and traditional auberges line the edge of the sand on the western side, forming a band of low buildings between the asphalt road and the first dune slopes.tourist accommodation along the dunes From the village, tracks and informal paths lead directly into the sand, and the contrast between built settlement and open desert is immediate.
Beyond Merzouga the landscape changes quickly into rocky desert, with the dune sea forming an isolated tongue of sand within a broader zone of semi-arid steppe. Nearby communities such as Hassilabied lie close to the northern margins, also facing the dune field, while larger towns including Erfoud and Rissani stand further away to the north in the Tafilalet basin.Erfoud and Rissani as reference towns Road access from these towns reaches Merzouga and continues along the western edge of the dunes, keeping the dune sea visually present along much of the drive.
Shape, scale and desert environment
The overall form of Erg Chebbi is a long, slightly curved strip of dunes aligned roughly north–south, with smaller ridges branching from the main line. Many dune faces are sharply inclined, while crest lines can be narrow and sinuous. Wind activity reshapes the surface, creating ripples on the flanks and smoothing footprints over time, but the broad pattern of high sand ridges above the surrounding reg remains a defining feature.length, width and dune heights
Vegetation in the dune field is sparse, limited to occasional grasses and small plants that take root where moisture from rare rainfall lingers. Beyond the sand, scattered acacias and low shrubs mark the transition back to stony desert. To the east the highest dunes stand relatively close to the border zone with Algeria, while to the west the sand gives way to the approach roads and built edge of Merzouga. With clear air and little obstruction, the sightlines from high dune crests carry over the erg, the village and the surrounding plains.
Visiting Erg Chebbi: what travellers from Western Europe should know
- Erg Chebbi lies in south-eastern Morocco near the Algerian frontier, with Merzouga as the gateway village on its western edge. Access by paved road links Merzouga to towns such as Erfoud and Rissani.
- The approach into the dunes involves walking on loose sand, where slopes can be steep and footing yields under each step.
- The terrain combines high dune ridges with surrounding rocky plain, and reaching the upper crests requires sustained uphill walking on sand.
- For visitors from Western Europe, the official language is Arabic and the currency is the Moroccan dirham.
- Entry requirements depend on your nationality; UK travellers can check the FCDO travel advice at gov.uk/foreign-travel-advice, Irish travellers the Department of Foreign Affairs at ireland.ie.
