Atlantis Submarines provide a daily submarine tour departing from Lahaina Harbor that takes you 120 feet below the ocean’s surface. On this odyssey, you’ll encounter the artificial reef created by the wreck of the Carthaginian. The total tour time is around 2 hours and departures leave every hour during the day. Morning times are a little better for visibility, but there really isn’t a bad time. On the tour, you’ll see a variety of underwater features including coral and many species of reef fish. Occasionally, guests of the Atlantis Submarine are treated to a white tip reef shark or during the winter months, a humpback whale has been known to make an appearance. There is also a glass-bottomed boat departing Lahaina Harbor called the ReefDancer. If your children are under 36″ tall, the minimum height requirement for the submarine, you’ll want to opt for the ReefDancer. It cruises the coast in front of Lahaina and even has a diver that goes out and finds cool stuff for you to see. Advance reservations are required and you can also book with ease by calling 855-268-0387.
