About this activity

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.
