Morocco's most iconic sand sea — soaring dunes at sunrise.
Erg Chebbi is one of Morocco's two great ergs — large seas of sand dunes. Stretching roughly 28km long and up to 9km wide, its dunes climb to about 150 metres — the tallest free-standing dunes in the country — and change colour from orange to gold to crimson with the shifting light. Ride a camel at sunset, drive the crests by 4x4, or simply walk up from Merzouga for a sunrise with the sand to yourself; however you meet it, a night between these dunes is among the world's great travel experiences.
