Glass-bottom Boat Reef Tour

Overview

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.

The crew was excellent. We saw pretty good fish activity. It was what we expected for a 50-minute activity. I would recommend it to anyone who doesn't necessarily do well on the water.

The boat captain and guide were wonderful. The guide was very knowledgeable and friendly. We were very disappointed about what we saw, plus one side of the boat had a much better view of things( not our side!)

Aloha, we’re sorry your time aboard was mixed. Glad you liked the captain and guide, but we regret the view from your side fell short. We value your input as it allows us to improve!
