Site details

North Shore shore dive/snorkel site inside the Pūpūkea Marine Life Conservation District. The cove and outside reef have lava tubes, caverns, arches, and swim-throughs, with better diving outside the shallow cove. It is generally a summer-only site because winter North Shore surf makes conditions dangerous.
