Sidi Chamarouch is a small Berber village at around 2,300 metres on the Ait Mizane valley path, roughly halfway between Imlil and the Toubkal Refuge. It clusters around a waterfall where the river drops over pale granite boulders, and its chief feature is a marabout shrine sacred to local Berber Muslims. The shrine is forbidden to non-Muslims but the village itself — a scatter of low stone buildings with a few stalls selling drinks and snacks to passing trekkers — is welcoming enough.
The site has been a place of pilgrimage long before Islam arrived in the Atlas, and the spirit venerated here is older than the Islamic saint's name layered over it. Pilgrims visit throughout the year, often arriving with livestock for sacrifice. Trekkers use it as a rest stop and turnaround point for day walks from Imlil; the waterfall is at its most impressive in April and May when the snowmelt is running.
