Site details

One of two navigable passages cutting through the Sha'ab Mahmud reef, running northwest to southeast and separating a sandy inner lagoon from the open sea. The channel is very shallow, with a maximum depth around 6m and reef walls roughly 2m high, and is typically dived as a tidal drift from the outer reef into the calm lagoon.
