These rocky tidal pools in Pupukea’s Marine Life Conservation District on Oahu’s north shore are famous for snorkeling and scuba diving. Despite its name, there are no sharks to be found here, but the cove boasts an impressive variety of marine life, including schools of fish, octopuses, sea turtles, and thriving coral. Visit in summer when the waters are calm, as the winter’s waves make for dangerous conditions. There are restrooms and limited parking but no lifeguards on duty. Also, wear water shoes as it’s easy to lose footing on the sharp and slippery rocks. – Tripadvisor
