Key Dive Site Facts
Dive Site Overview
The underwater landscape here unfolds as a dynamic mix of varied topography, encompassing both artificial and natural elements. Divers venturing from the jetty and turning right (east) will encounter a series of purpose-built reefballs.
These spherical structures are strategically placed, creating essential artificial habitats that attract and shelter a diverse array of smaller marine organisms. As one progresses further into the dive, substantial concrete plates become a dominant feature, sloping gradually downwards from shallower areas to depths reaching approximately 15 m / 50 ft. These robust slabs form an accessible, structured pathway for exploration, frequently revealing invertebrates and fish nestled within their angles and crevices.
Directly opposite the jetty, the weathered remnants of an old breakwater extend, forming a transitional zone that leads towards these deeper concrete sections. Beyond these prominent structures, the site transitions into expansive sandy bottoms interspersed with scattered oyster banks.
These areas provide contrasting environments, offering opportunities to spot burrowing flatfish or observe hermit crabs moving across the substrate. While many key points of interest are concentrated within the upper twenty meters, the dive site itself extends to its reported maximum depth, allowing for varied profiles based on diver experience and air consumption.
Most divers find rich exploration by focusing on the defined structures and their immediate surroundings, typically remaining at shallower profiles.
Best Time to Dive
