Between Ouarzazate and Tinghir, the road follows the foot of the High Atlas past kasbahs, palm groves and two spectacular gorges.
The Dadès Gorge
Drive up from Boumalne to see the famous hairpin bends, best in the late afternoon light.
The Todra Gorge
Near Tinghir, the canyon narrows between walls hundreds of metres high. Walk in early in the morning, before the day trippers.
