Erfoud is a French-built administrative town from the 1930s, its dusty red buildings giving it a pleasantly sleepy, almost ghost-town atmosphere. The town itself is modest, but it sits at the gateway to some of Morocco's most extraordinary desert scenery. The road south from Er-Rachidia is spectacular — ancient Berber kasbahs rising from palm groves that stretch as far as the eye can see.
Most travelers use Erfoud as a base rather than a destination. From here you can reach Merzouga and its famous Erg Chebbi dunes, or head to Rissani, a historic oasis town with a crumbling palace and a lively market. If you're lucky, you might experience a full desert sandstorm — a disorienting, all-encompassing event that briefly turns the world orange.
