Glass Bottom Boat


See the underwater world without getting wet!

Board this semi-submarine for Maui's Ultimate Underwater Glass Bottom Boat Viewing Adventure and Dive Show. Departing from Lahaina Harbor, this tour shows you the only barrier reef in Maui. You'll have the opportunity to see various kinds of coral as well as reef fish such as the Humuhumunukunukuapua'a, Hawaii's state fish.

Once we are out to the best viewing site, you can sit in front of the big windows in our underwater viewing cabin for a up-close view of the reef. This is when our divers will jump in the water and search the bottom for exotic critters they can bring right to your window -a great photo opportunity! Our experienced narrator will help you learn more about the world of Maui's reef.

This tour of the underwater world of Maui features
  • An air-conditioned underwater cabin
  • Window seats for everyone
  • Dive show
  • Free fish chart and postcard
  • Visit turtle sites

On the way back to the marina, guests can ride up on the top deck and get an amazing view of the beautiful West Maui mountains from the water. In fact, you can ride up top anytime you like during the trip.
