This cove got its name from a story that says that the outline of the reef outside the cove looks like a shark, when seen from above. It is a lava-rock beach on the North Shore of Oahu. There are beautiful underwater rock formations, and fish and sea turtles are usually in the cove. It is a favorite spot among snorkelers and scuba divers. It is a good idea to wear reef shoes because of the sharp coral reef that is everywhere. The lava has formed underwater caves and tunnels about 15 to 45 feet below the surface. These caves are a real thrill for experienced scuba divers. Please don't attempt to go in them if you are not Cavern Diver Certified. As you can see below, I got carried away with taking pictures of all the different rock formations and other interesting things. In a future visit, I will bring my scuba gear and do some underwater photography.
