Locals might lead you into the gorge for a few dirham, but you can follow well-trodden paths to viewing points and down into the gorge. Along the way, Barbary apes clamour for attention – though a signpost advises not to feed them.

At the bottom, you can hike further along the riverbed to more peaceful pools where you can swim, or cross the river to another path for extended hikes. To see the picturesque Berber village of Tanaghmelt, follow the path by the lower pools past a farmhouse and up the slopes for about 1.5km. For longer treks, follow the course of the river to the Gramaa Nakrouine caves (two hours) and the Gorges of Oued El Abid (another two hours).
