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.

The glass bottom boat tour was amazing! The captain and crew were very knowledgeable of the area. It was a few you wouldn't be able to see otherwise, especially for younger kids who aren't comfortable snorkeling yet. You could see the ocean floor over 100 feet down.

Staff was friendly and very knowledgeable about fish and sea life we saw. We got great information about Hawaiian Islands and the history and culture of the area. The reefs we went to had abundant ocean life to view.

Naturalist Eden made this trip spectacular. Funny, knowledgeable… We learned a lot, and we're entertained in our journey. We saw a multitude of spinner dolphins, which was an unexpected bonus. Captain Sean, first made Sara helped to make the experience lovely
