The Grand Erg Oriental, meaning the “‘Great Eastern Sand Sea”, is a large erg or “field of sand dunes” in the Sahara desert. Situated for the most part in Saharan lowlands of northeast Algeria, the Grand Erg Oriental covers an area some 600 km wide by 200 km north to south. The erg’s northeastern corner spills over into neighbouring Tunisia.

In a desert region, an erg is an area of large accumulation of sand, generally in the bottom of a huge basin in which a former river piled up alluvium. Ergs are areas of actively shifting dunes, “fossilized” dunes, or extensive sand sheets. The sand is generally loose and is extremely difficult to cross.
