Take a Submarine Ride—The Atlantis Submarine takes you and the kids down into the shallow coastal waters off Lahaina in a real sub, where you’ll see plenty of fish (and maybe even a shark!). They’ll love it, and you’ll all stay dry the entire time. Allow about 2 hours for the trip.
Sleep with the Sharks—What do fish do when the lights go out? Find out during one of the family sleepovers at the Maui Ocean Center. The fun starts at 7pm, when kids help feed the turtles and rays, witness sharks and jacks on the prowl in the Open Ocean exhibit, and then snuggle into their sleeping bags. Note: Each child must be accompanied by an adult. The $75 per-person fee includes snacks, breakfast, a souvenir, and aquarium admission the following day.
Tour the Stars—After sunset, the stars over Kaanapali shine big and bright: That’s because the tropical sky is almost pollutant free and no big-city lights interfere with the cosmic view. Amateur astronomers can probe the Milky Way, see the rings of Saturn and Jupiter’s moons, and scan the Sea of Tranquillity in a 60-minute star search on the world’s first recreational computer-driven telescope. It takes place nightly at 8 and 9pm on the rooftop of the Hyatt Regency Maui Resort. The cost is $30 for adults and $20 for children 12 and under. (There’s also a 10pm tour for couples only; it’s $45, and champagne and chocolate-covered strawberries are served.) Reservations are a must.
