The south provides a mix of shore-diving and boat excursions to the likes of the Dolphin House and Elphinstone sites.

Seven-night holidays in Shams Alam, with B&B rather than half-board, start from £678pp, while those in the even more southerly Hamata, offering easy access to Fury Shoal, are all-inclusive (except alcohol) and start from £685pp.

Seven-night safaris on liveaboards operating from Port Ghalib (pictured) start from £887pp, including six days' diving.
