The R 704 follows the course of the Dadès River north from Boumalne-du-Dadès. Starting at Ait-Oudinar the river has carved out beautiful deep gorges, flowing at the foot of vertiginous walls and bordered by a thin strip of greenery. The setting changes at the village of Imdiazen, where the Dadès enters a verdant valley before reaching another landscape of more modest gorges around Msemrir. Make use of the many overlooks on the road where you can peacefully enjoy the superb panoramas!
