13 Hanauma Bay

If you love snorkeling, then Hanauma Bay will be right up your alley. The coral reefs underneath gemstone-colored waters are part of a marine preserve, so this attraction is closed on Tuesdays. You can hire equipment when you arrive, and there are lockers, changing rooms, and showers if necessary. Again, you'll need to go early to miss the crowds and see clearly. Schedule at least two hours to get your fill.
