The Dades valley lies to the south of the Atlas mountain range and due to the limited rainfall is a desertic and semidesertic area. Red is the dominant colour of the valley, due to the reddish mountains, rocks and stones in and around the valley. There are several oasis towns spread around the valley. The Todra gorge is particularly scenic, as the canyon narrows to a flat stony track wide as little as 10m wide in places with sheer and smooth rock walls up to 300m high on each side.
