Erg Chebbi in Merzouga: Morocco’s great dune sea
Published on 08/29/2026 at 21:03 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Erg Chebbi is the best known sand dune field of south?eastern Morocco, a great sweep of Sahara sand rising directly beside the village of Merzouga near the Algerian border. Stretching for many kilometres and reaching dune heights of around 150 m (about 500 ft), it forms a compact “sand sea” that stands out sharply against the surrounding stony plain.
The shape and scale of Morocco’s Erg Chebbi
Erg Chebbi is an erg, the term used in Arabic and geomorphology for a broad field of dunes formed by wind?blown sand. The dunes occupy a relatively narrow strip of desert, extending for roughly 22 to 28 km from north to south and around 5 to 7 km across, with the sand mass aligned close to the frontier with Algeria.Erg Chebbi is one of Morocco’s ergs In contrast to the flat hamada – the rocky desert that surrounds it – the erg rises in sharp, flowing ridges whose slopes can reach heights in the region of 150 m (about 500 ft) above the adjacent plain.dunes reaching up to 150 metres
The field is compact enough that its outer limit is visible from many vantage points, giving a clear sense of its dimensions in the landscape. Walking out from the hard desert into the first ridges, the sand soon deepens underfoot as the path moves between wave?like forms that run broadly parallel along the length of the erg. At higher points the crest lines present long views over both the dune system and the grey?brown hamada beyond, emphasising the transition between bare rock and soft sand.
Merzouga: gateway village on the edge of the dunes
Merzouga lies on the western side of Erg Chebbi and acts as the principal gateway settlement for the dune field. A cluster of houses, lodges and small hotels lines the edge where the compact village meets the rising sand, forming a narrow strip of habitation between the hamada and the first dune slopes.Merzouga stands on the western lee of the dunes From here, unpaved tracks and paths lead directly into the erg, and the first major dunes begin only a short distance from the last buildings.
The village sits in Morocco’s Tafilalet region in the south?east of the country, far inland from the Atlantic and relatively close to Algeria.Tafilalet setting near the Algerian border Road access runs via towns such as Erfoud and Rissani, with a paved route leading straight to Merzouga and the edge of the sand. Around the village a scattering of auberges and desert camps cluster along the base of the erg, forming a band of accommodation that follows the line of the dunes.
Sand, colour and desert light in Erg Chebbi
The sand of Erg Chebbi has a fine, loose texture that lends itself to rippled surfaces and sharply cut crest lines. Wind action reshapes the ridges continuously, creating fresh slip faces and renewing the patterns along the dune flanks.the dunes form a sea of wind?blown sand In strong light the colour ranges through shades of gold and orange, while low sun accentuates shadows and gives the sand a deeper tone.
Because the erg stands on otherwise bare desert, the contrast in texture is immediate once the sand begins. The rocky ground breaks into smaller fragments as it approaches the dune margin, then gives way entirely to loose grains where vehicle tracks and footprints mark the approaches. From within the field the outer rock plain can appear as a level horizon, while the dunes around form a series of overlapping silhouettes.
Visiting Erg Chebbi: what travellers from Western Europe should know
- Erg Chebbi lies in south?eastern Morocco, immediately east of Merzouga and close to the border with Algeria; it is reached overland by road via Erfoud and Rissani.
- The terrain in the dune field consists of deep, loose sand with slopes on many faces; walking involves short, steep climbs and descents, and vehicles use established tracks at the margins.
- Erg Chebbi is in Morocco, where 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.
