Sharks Cove, Three Tables, and the tide pools of North Shore
Pupukea is an umbrella name for the rocky shoreline area on Oʻahu's North Shore between Waimea Bay and Sunset Beach. It encompasses two distinct snorkeling areas: Sharks Cove to the north and Three Tables to the south. Both share the same parking lot off Kamehameha Highway.
Visitors searching for "Pupukea Beach" often end up confused because maps may show any of three names for this area. Sharks Cove is the most popular snorkeling spot. Three Tables is named for flat reef formations visible at low tide. The official park name is Pupukea Beach Park.
This area sits below a residential hillside. After rain, runoff from Pupukea Road and surrounding neighborhoods can carry bacteria into the tide pools. The enclosed nature of the tide pools means contamination lingers longer than at open beaches. Check live advisories and avoid the area for 72 hours after storms.
