The large and heavily vegetated island of Juani, southeast of Mafia, has overgrown but evocative ruins at Kua. This includes the remains of several mosques dating from a Shirazi settlement during the 18th and 19th centuries, and crumbling palace walls. Also note the ablutions area just to the right of the main entrance to the settlement. Access to the ruins is only possible at high tide. South of here is a channel and a nearby lagoon for birding and swimming.
