Shark's Cove, Oahu

Despite its daunting name, Shark’s Cove is an inviting, must-see destination on Oahu. This lava-rock beach is part of the 80-acre North Shore Marine Sanctuary, a conservation district that has been vigorously maintained by marine enthusiasts. The result of this vigilance is that a spectacular underwater world has formed at Shark’s Cove, complete with white-tipped reef sharks, schools of tropical fish and sea turtles. The sharks are non-aggressive, though visitors should take caution not to disturb or to intentionally approach these harmless sea creatures.

In addition to its lush marine life, Shark’s Cove is also known for the stunning underwater caves and tunnels (ranging from about 15 to 45 feet ( 4.5 to 13.7 m) that have been formed over the years out of lava rock. This surreal submarine world entices scuba divers and snorkeling fans from all over the world.

The summer months are the best time to explore the cove, as the water is peaceful then. Visitors should avoid entering the waters during the winter when waves as high as 40-50 feet pummel the cove and create an extremely dangerous environment for even the most seasoned swimmers. There are no lifeguards on duty at Shark’s Cove, and beachgoers who wish to swim in the waters are advised to wear reef shoes because of the ubiquitous sharp coral reef.

The area is equipped with restrooms and shower facilities, and free street parking is readily available. As Shark’s Cove is part of a conservation district, it is prohibited to collect shells or touch any marine life in the area.
