This loop leaves from Marrakech airport and comes back to it, and over nine days it links the three faces of Morocco: imperial cities, high mountains and Sahara. You head south-east first, crossing the High Atlas at the Tizi n'Tichka, and follow the pre-Saharan valleys down to the Erg Chebbi dunes; the route then turns north over the Middle Atlas to reach Fes and comes home via Meknes, Rabat and Casablanca.
Road days and walking days take turns here. Day 2 in Marrakech and day 6 in Fes are each spent entirely in a single city, with a local guide who knows the medina from within; in Fes el-Bali, that is the only way to move around without going astray. Midway, on day 4, you sleep at the Merzouga camp, reached by camel at sunset, and on day 5 you watch dawn break over the dunes.
You sleep seven nights in hotels and one in a tent in the desert, with breakfast and dinner provided throughout. On day 9 the circuit ends where it started, at Marrakech airport.
