Sharks Cove is located on Oahu’s magnificent North Shore, between Sunset Beach and Waimea Bay. In the wintertime, this area has some of the largest waves in the world, but in summer time, it is calm and boosts some of the best snorkeling on the island. You will find reefs with caves, lava tubes and fantastic coral outcroppings. Depths in this area run to 60 feet, but diving is easy and it’s often used as a training area for scuba diving.
