Kehena Beach is one of the Big Island's few clothing-optional beaches, located within the island's Puna district. The beach was originally formed in 1955 from uphill lava flows and dropped nearly three feet toward sea level following a strong earthquake in 1979, causing its concrete beach stairs to break off. Today, the beach is commonly known as Dolphin Beach because of its populations of spinner dolphins, which can be observed throughout the year. The long, narrow black sand beach is also a popular spot for swimming during calm water conditions, though visitors should note that sudden strong undertows and rip currents can cause near-drowning incidents.
