Situated in the vast desert region of Saharan Morocco, dividing Morocco and Algeria, Erg Chebbi is one of two Moroccan ‘ergs’, which are a sea of dunes. What it lacks in size - compared to the deserts of Algeria, Libya and Namibia - it makes up for in its extraordinarily scenic golden landscape, which changes colours dramatically at sunset. The dunes of Erg Chebbi span over 30 kilometres and rise up to 160 metres. From Merzouga, the tourist centre, take a camel trip into the wild; enjoy quad biking; or stay overnight in a desert oasis called a Moroccan bivouac.
