Sharks Cove and Cathedrals, all experience levels!

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 some of the dives we offer at Banzai Diver Hawaii.

I have been diving all over the world but nothing quite compares to the sea life here. Going out to some of these underwater landscapes is like being on a different planet. This is the best tour for lava tube diving.

We have had the pleasure diving in many coral reefs around the world but this was our first time we have ever died near lava tubes. If you have never been diving in these areas before, this is an experience that you have got to try. I was amazed at the life here!
