Before the golf courses, condos and luxurious resorts, sleepy little Keauhou Bay was the birthplace of a king. In 1814, when Queen Keopuolani gave birth here, it was first believed that her infant son had died a stillborn death. When a priest managed to revive the infant by placing him upon a stone, the child would live to be Kamehameha III—the longest ruling monarch of Hawaii.
Today the Kauikeaouli Stone is on the National Register of Historic Places, and the bay is also the launching point for snorkeling tours to Kealakekua Bay. At night, dozens of manta rays visit Keauhou to feed on schools of plankton, and twilight snorkeling tours and evening scuba dives have become some of the most popular activities on the Big Island. In addition to snorkeling and diving, standup paddle and kayak rentals are available at the oceanfront park.
Keauhou Bay is located seven miles and 15 minutes south of downtown Kona. There is parking available on Kamehameha III road, and Keauhou Beach Park has showers, restrooms and a small black sand beach. Swimming, however, is not advised due to the high level of boat traffic.
