Frigate Passage – Beqa Lagoon and Pacific Harbour
Site Overview
Frigate Passage is a coral-rich passage dive on the outer edge of Beqa Lagoon, distinguished from the neighbouring Beqa Passage by its emphasis on hard coral formations and abundant turtle populations. While the Beqa Passage is known for its adrenaline-charged drift diving and pelagic encounters, Frigate Passage offers a more relaxed experience with spectacular coral gardens and frequent encounters with green turtles and hawksbill turtles that feed on the extensive hard coral reefs. The passage channels moderate currents that nourish expansive hard coral tables, staghorn thickets, and brain coral bommies that support a diverse community of reef fish. Large parrotfish graze on the coral substrate, producing the fine white sand that characterises tropical beaches. Moray eels of several species peer from crevices in the coral framework, while octopus change colour as they hunt across the reef surface. The turtle population at Frigate Passage is notably higher than at other Beqa Lagoon sites, with multiple green turtles commonly encountered on a single dive, feeding on algae growing on the coral substrate or resting on sandy patches between the coral heads. Hawksbill turtles, though less common, are regularly observed feeding on sponges growing in the deeper crevices. The passage topography creates a gentle drift that carries divers along the reef slope, allowing them to cover a large area and observe the rich biodiversity without excessive finning. The site is particularly popular with underwater photographers who appreciate the combination of healthy coral landscapes and charismatic megafauna.
Dive Briefing
"Divers enter from the boat and descend to the reef slope at approximately 10 to 15 metres depth. The current carries divers gently along the reef in a controlled drift, allowing ample time to observe the hard coral formations and search for turtles. Green turtles are commonly encountered feeding on algae-covered coral bommies or resting on sandy patches between the reef structures. The reef slope is covered in extensive hard coral growth including table corals, staghorn thickets, and massive brain corals that create a complex three-dimensional habitat. Schools of parrotfish graze noisily on the coral substrate, while moray eels extend their heads from crevices to monitor passing divers. The drift continues along the reef edge where the current is strongest and pelagic species occasionally appear. Deeper sections at approximately 25 to 30 metres host larger coral bommies with overhangs sheltering glassfish and cardinalfish. The guide leads the group along the most productive section of the reef, pointing out turtles and interesting macro life. After approximately 45 minutes of drift diving, divers ascend for a safety stop on the DSMB. Total dive time is approximately 50 to 60 minutes."

Traveler Notes
Who is this for?
Frigate Passage is perfect for intermediate divers who enjoy coral reef diving with abundant marine life and the thrill of frequent turtle encounters. The moderate currents and accessible depth make it suitable for Open Water certified divers with some experience, though Advanced Open Water divers will appreciate the deeper sections. Turtle enthusiasts and underwater photographers will find excellent opportunities for close encounters and natural behaviour photography. The site is less demanding than the Beqa Passage drift dive, making it a good alternative for divers who want passage diving without the strong currents. Marine biology students and naturalists will appreciate the healthy hard coral ecosystem and the diverse reef fish community. The gentle drift makes it enjoyable for divers of all experience levels who want to cover a large area with minimal effort.
For Non-Divers
