Broken Ledge, Havelock Island: canyons and pelagic encounters

Broken Ledge is defined by its unique topography: low rock outcrops emerging from the sandy bottom, forming a complex series of broken ledges, rifts, and mini-canyons. These formations, sometimes compared to a crashed flying saucer with one side buried, create a varied terrain that promises new discoveries with each dive. The structure itself drops from 9 to 30 metres, offering different depth zones to explore, from shallower plateaus to deeper sections with more pronounced rock walls and crevices. The site was first charted in 2010.

Navigating Broken Ledge often involves exploring these hidden canyons and overhangs. Within these sheltered spaces, you will discover giant moray eels (Gymnothorax javanicus) peering from their rocky hideouts, alongside other benthic life such as lobsters and shrimp. The intricate architecture of the site provides ample opportunities for close inspection, allowing you to observe the smaller inhabitants that thrive in these protected environments. Keep a close eye on the crevices, as you may also find octopus (Octopus vulgaris) and nudibranchs (Nudibranchia) tucked away.

The rocky formations of Broken Ledge are teeming with an incredible density of resident reef fish. Swarming around the ledges and through the open water columns are vast schools of longfin bannerfish (Heniochus acuminatus) and snappers (Lutjanidae). You'll also encounter the distinct patterns of marbled groupers (Epinephelus merra), lionfish (Pterois miles), and large Napoleon wrasses (Cheilinus undulatus) moving gracefully across the reef. These populations form a vibrant backdrop to the more transient visitors.

Beyond the immediate reef life, Broken Ledge is a known location for pelagic encounters. White-tip reef sharks (Triaenodon obesus) are frequently spotted patrolling the deeper sections of the site, often resting on the sandy bottom or cruising along the reef edge. Large schooling fish, including dogtooth tuna (Gymnosarda unicolor) and yellowfin tuna (Thunnus albacares), are regular visitors, indicating the site's connection to deeper, open-ocean currents. These encounters add a dynamic element to the dive, encouraging regular scanning into the blue.

You can also expect to encounter larger rays at Broken Ledge. Marbled rays (Taeniura meyeni) are sighted here, often gliding along the sandy stretches adjacent to the main reef structure. During the season from November to May, manta rays (Mobula birostris) are known to visit, passing by the ledges, making for impressive moments in the blue. Keep an eye out for these graceful giants as you explore, especially away from the immediate rock formations.

Sea turtles (Cheloniidae) are a consistent presence at Broken Ledge, often seen navigating the rifts and gaps within the rocky terrain. Their calm demeanor allows for observational approaches, and you might spot them foraging amongst the corals or resting in sheltered spots. Sea kraits (Laticauda colubrina) also make an appearance, particularly exploring the cracks and deeper crevices of the ledges, adding another dimension to the site’s diverse ecosystem.
