Our tours depart from the Kailua-Kona pier on the Big Island of Hawaii. Discover the beauty of Kona's underwater world aboard Marian, a 36-foot (10-meter), custom-designed glass-bottom boat. Your expert naturalist guide provides insight to the world of corals and colorful tropical fish. View Kona's coastline, mountains, historical sights, and maybe even spot frolicking dolphins or seasonal whales. This 50-minute tour is a must for all ages, from kids to avid divers and snorkelers eager to learn more about Hawaii's unique marine life. Bring along your camera and wear comfortable clothing and footwear. Sit back and relax while the boat skims over the reef, putting you within inches of the underwater world. Marian was specially designed and built for just this experience.
Note: We are located on the Big Island of Hawaii. Please ensure you are on the correct island prior to booking. We cannot wave our cancelation/refund policy for booking when on a different island.

on time, great tour, enjoyed the view thru the glass windows, a little too much verbal review by the host person

As lovely as it was to be able to see through the panes in the bottom of the boat, the best part of the tour was Brittney, the host, or emcee, or tour guide -- whatever you want to call her. She was SO knowledgeable, as well as skilled at moving from topic to topic as the sea life did their thing. She was terrific! And the reason to take this tour!

This was a charming tour of the reef with some great views of fish, a few eels, and puffer fish! It’s perfect for those with little ones (we had a 3 and 1 yr old) and they are super informative about all the fish. They provide ginger ale, a ginger candy (if you feel queasy), and it’s nice to be in shade. Great little way to see beautiful fish and get a little education!

It was very interesting to find out that the maker of the boat was the father of one of the guides and he made it himself. The boat was lovely. The captain and all the crew were wonderful. They were very knowledgeable about the reefs and the fish and it was very beautiful unique experience.

We got a glimpse of dolphins, and the fish were nice. Hoped to see a lot more. It was ok. If I had kids it would have been good for them but as adults we were not overly impressed.

We did not see hardly anything. The trip was only 45min long and you didn’t go very far from where you ported. Save your money.

Great way to spend an hour learning a little about Hawaiian history, the surrounding reefs and local fish.

There was ample space to view through the windows and plenty to see. It was a last minute add-on to our trip that was well worth the money.
