Kona Glass Bottom Boat is a family-run eco-tour inviting you to discover Kailua Bay’s vibrant reef without getting wet. Aboard Marian—the hand-built wooden vessel that skims just 2½ feet above the coral—guests drift within inches ...
This family-run operation consistently impresses visitors with its warm, knowledgeable crew who genuinely seem to enjoy what they do. Amy and the captain get frequent shout-outs for being entertaining, informative, and skilled at managing groups of all ages. The boat itself is unique—built locally on the Big Island—with exceptionally clear viewing windows that give everyone a great vantage point to see coral reefs, tropical fish, and occasional dolphins or octopuses swimming by. The experience works particularly well for families with young children or anyone who can't or doesn't want to snorkel but still wants to see what's beneath the surface. Parents appreciate thoughtful touches like providing ginger drops and patches for seasickness, keeping passenger numbers reasonable so the boat doesn't feel crowded, and having sea animal toys to keep little ones entertained. The 50-minute tour seems to fly by in the best way, with plenty to see and engaging commentary throughout. One reviewer mentioned a frustrating booking cancellation issue, though this appears to be an isolated incident rather than a pattern.
This was a wonderful experience for my whole family. Very informative and fun!
