Beqa Lagoon, 12km south of Pacific Harbour, is renowned for its shark-feeding dives, which attract divers from across the world. On a good day you may see up to a hundred sharks over the two dives, including reef sharks, silvertips, tawny nurse sharks, sicklefin lemon sharks, menacing-looking bull sharks and the occasional tiger shark, as well as schools of other large fish taking advantage of the free food (mostly tuna heads from a nearby factory). The best dive sites are on the western tip and north side of the lagoon, best accessed from Pacific Harbour, where accommodation is more affordable and dining more diverse than on the island of Beqa itself.
Both of the companies here claim an excellent safety record, but if you fancy a more sedate experience there are also soft coral and wreck dives available in the lagoon on the days that the sharks are not fed.
