Sanganeb is a long ellipse of reef with a shallow lagoon at its centre and a lighthouse on its southern tip. It offers two main dive sites: a long ridge at the north end and a stunning plateau to the southwest. The north ridge tumbles down to about 55m. Hammerheads are regularly seen in the blue. The south plateau is a mixture of sand and soft-coral-covered pinnacles at about 25m, patrolled by grey reef sharks. Groupers, jacks, barracudas and sharks dominate this zone.
