The Pinnacles Beqa – Beqa Lagoon and Pacific Harbour
Site Overview
The Pinnacles at Beqa is a submerged seamount rising from the depths of the outer Beqa Lagoon passage, creating an underwater oasis that attracts swirling schools of fish and hunting pelagic predators from the surrounding blue water. This isolated pinnacle rises from approximately 35 metres depth to within 8 metres of the surface, its summit crowned with dense coral growth and surrounded by clouds of schooling snapper, sweetlips, and anthias. The seamounts position in the nutrient-rich passage ensures a constant supply of plankton that sustains the prolific fish populations, which in turn attract larger predators including dogtooth tuna, giant trevally, and grey reef sharks. Hunting tuna can be observed making lightning-fast strikes into the baitfish schools, while giant trevally patrol the flanks of the pinnacle with calculated aggression. The summit of the pinnacle is bathed in sunlight during shallow portions of the dive, creating a stunning visual contrast between the colourful coral community and the deep blue water surrounding the isolated structure. Schools of snapper and sweetlips form dense aggregations that swirl and reform as predators pass through, creating mesmerising patterns for wide-angle photography. The deeper flanks of the pinnacle host larger gorgonians and black coral, while crevices provide shelter for lobsters and moray eels. The Pinnacles is considered one of the more exciting dives in the Beqa area, combining the thrill of pelagic encounters with the beauty of a healthy coral-covered seamount rising from the deep.
Dive Briefing
"Divers descend from the boat to the summit of the pinnacle at approximately 8 to 12 metres depth. The summit is covered in dense hard and soft corals with clouds of anthias and schooling fish creating a spectacular visual display. From the summit, divers work their way down the flanks of the pinnacle, observing the schooling snapper and sweetlips that congregate in large numbers. Dogtooth tuna and giant trevally patrol the perimeter, occasionally making high-speed runs through the baitfish aggregations. Grey reef sharks cruise the deeper flanks, their silhouettes visible against the blue water. The current flows around the pinnacle, creating upwellings on the upstream side that concentrate plankton and attract feeding fish. Divers should use reef hooks on the upstream face to observe the action without excessive finning. The deeper sections at 25 to 35 metres host larger gorgonians and black coral with sheltering lobsters and moray eels. Multi-level diving is recommended, spending time at the summit for photography before descending to observe the deeper pelagic action. Safety stops are conducted on the DSMB above the pinnacle summit. Total dive time is approximately 45 to 50 minutes."

Traveler Notes
Who is this for?
The Pinnacles is designed for advanced divers who enjoy pelagic action and dramatic underwater topography. The deeper profile and moderate currents require Advanced Open Water certification with good air management skills. Wide-angle photographers will find exceptional opportunities to capture schooling fish, hunting tuna, and the dramatic seamount structure against blue water. The site rewards patient divers who take time to observe the predator-prey interactions around the pinnacle. Divers interested in marine ecology will appreciate the seamount ecosystem and the way it concentrates life in the open water. The site is less suitable for beginners due to the depth and current conditions.
