Sharks Cove Lava Tube Scuba Dive

Disclaimer: Available May through September Only

Beautiful and unique dives in world renown Pupukea Marine Life Preserve, known locally as "Sharks Cove" Here we encounter amazing underwater topography such as lava tubes and tunnels, trenches, arches and an abundance of protected marine life such as turtles, monk seals, octopi, rays, and a plethora of native fish. With max depths of around 45ft, this site is perfect for all experience levels!


A lava tube is a lava cave that can form when lava, or pahoehoe in Hawaiian, flows beneath the surface of hardened rock. As the underground flow slows and cools, tunnels can form as it creates a crust around itself. Underwater, this creates a truly spectacular seascape few people see. Tunnels, caverns, arches, pillars, and trenches resulting from this geological process are spread throughout this scuba dive tour.
