One of the prettiest beaches on the Big Island, Hapuna is a long expanse of beautiful white sand. It’s a great place to relax on the sand or swim, and sometimes the surf comes up enough for some body boarding. The state charges $10/day per vehicle, plus $5/person to park. If you want to go for sunset, though, the beach is open until 8pm, and you don’t have to pay if you arrive after 6.
