Dive-site story
Located along the northwest coast of Dominica off Cabrits National Park, this dive site takes its name from a massive volcanic boulder sliced by a deep, accessible fissure. Divers explore the swim-through cleft, which is lined with encrusting sponges, tunicates, and deep crevices sheltering nocturnal critters, before moving onto the surrounding boulder fields and sloping reef.
Distinct volcanic boulder formation split cleanly down the center into a wide swim-through canyon
Sheltered overhangs harboring cryptic macro life such as longsnout seahorses and frogfish
Dense growth of barrel sponges, wire corals, and sea fans across the surrounding volcanic substrate
