Kehena Black Sand Beach

If you want to swim with dolphins but can't afford the price, you might want to explore Kehena Black Sand Beach. You may stand on the cliffs above and wait for the wild pod of dolphins that swims past the rocks.

Kehena Beach, located in the Puna section of the Big Island, is one of Hawaii's few unofficial "clothing optional" beaches. It is a long narrow black-sand beach known to locals as Dolphin Beach due to the regular occurrences of spinner dolphins in the vicinity.

Swimming is only feasible when the water is calm since the beach is exposed to the open ocean, and powerful rip currents and undertows can occur during heavy surf times.
