The kasbah sits in the northwestern corner of the medina, a fortified complex with thick ochre walls that encloses a small ethnographic museum and a walled garden. Entrance is cheap and the museum is modest — a few rooms of traditional costumes, pottery, and photographs of old Chaouen — but the garden is genuinely lovely: orange trees, bougainvillea, and a central fountain, completely calm in contrast to the busy plaza outside.
Climb to the top of one of the towers for views over the medina's blue rooftops and up to the rocky peaks of the Rif. The admission is well worth it for the garden alone, and the museum gives useful context for the town's Andalusian heritage. Go in the morning before tour groups arrive.
