This is one of the Big Island's best places to swim, sunbathe, picnic and bodysurf. A dirt road off Highway 19 leads out to Mahai'ula Beach, where a picturesque crescent of golden sand meets the head of a protected bay. Kua Bay, located about a four-mile hike north from the beach, is a good place for more activities. Divers frequently visit the underwater tunnels and the shipwreck off shore. Vehicles that aren't four-wheel-drives will have a difficult time with the one-mile unpaved road to the beach.
