Site details

The smallest of the four Tiran reefs but considered the most marine-life-rich, typically dived as a drift on its current-swept walls. Its celebrated 'Thomas Arches' are a series of deep coral arches beginning around 35m and descending to roughly 90m, reserved for technical divers, while strong and shifting currents make even the recreational profile demanding.
