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.

We loved our experience on the Glass Bottom Boat! We boarded at 9:55am for the 10am one-hour Cruise, from Slip #6 at Lahaina Harbor. The crew immediately greeted us with smiles and safety information. We also met the owner Heidi (who has great taste in handbags ;) ) who was wonderful to talk to. Once on the vessel, our trip was narrated by crew member Lena. She was informative, passionate, and funny- and we could tell she loved her work on the Glass Bottom Boat. We saw so many fish!! We also saw an Octopus, thanks to the amazing crew members/divers. It was clear and beautiful and everyone seemed to have a good time. No bathrooms so go beforehand- climate controlled so no need to stress about that! Overall a great experience! Thank you!

The crew was knowledgeable and friendly and my husband enjoyed the tour. The viewing area is below the water line and the motion was a little too much for me until I went to the deck. The crew was prepared with ginger candy and ginger ale. The divers did their best to find interesting sea urchins, shells and so on but nature is unpredictable and we didn’t see any turtles or sharks. The water was clear and the reef was beautiful.

The Glass Bottom Boat is a great way for people not able to actually get into the ocean and enjoy firsthand the beauty and treasures which lie under the sea; especially good for people with very small children who aren't old enough to snorkel. The 60-minute tour is just the right amount of time, as I think that the 90-minute tour would be too long as the cabin is very warm, with very little airflow; and a bit clausterphobic. Being up top on the deck smells very strongly of diesel fuel; making you nauseous. When heading out of Lahaina Harbor, and back in - you are able to view the gorgeous West Maui Mountains and majestic scenery from up top (if the diesel fuel smell doesn't make you too sick & nauseous); which is just an added perk to the excursion! Although there really wasn't much to see at the coral reef that we visited, this excursion has two divers bring up treasures from the bottom of the sea; and which they share with the guests through the glass windows. On our particular outing, the divers brought up 3 different creatures for the passengers viewing (an octopus, pin cushion sea urchin & sea urchin). Unfortunately this particular day very few fish were at the reef; consisting of just a few yellow tang and black trigger fish. So all in all, not a great viewing day; certainly not the crews fault! We had a wonderful time on this tour. The staff was extremely friendly and a wealth of knowledge. We learned a lot about the island, its waters, and marine life. Wish we had done it at the beginning of our vacation instead of at the end. They made time to answer questions and explain things.

This is a "must-do" activity, especially if you have little children who likely can't go snorkeling. We did the 90 minute tour and saw so many amazing...
