This mountain range marks the separation between the arid climate region in the north and the Sahara climate region in the south. Coming from the north, what's amazing is that there is no real pass; the route simply drops to reveal the immensity of the plains southward. There, a long-forgotten track deviates from the main road. Hidden from prying eyes, but with a fantastic view, you can pitch your tent and bask in the beauty of this place.
