YOUR BIG ISLAND REEF ECO-TOUR STARTS HERE
Kona Glass Bottom Boat Tours
Join us aboard “Marian” Kona’s Glass Bottom Boat. This wooden boat was built on the slopes of Hualālai mountain in the ’90s by founder Capt. Ralph and Jeannie Jewell. The business is still in the family, and is now run by his daughter, Amy, and her husband Dustin.
Marian draws only 2 1/2 feet of water which means it can safely bring guests within inches of the coral reef.
We offer fun, educational, reef tours with an onboard narrator. We also offer private charters including Ash Scatterings at Sea, Private Sunset Charters, and private reef tours. See the links above for more information and book your glass bottom tour in Kona online today!

We really enjoyed this excursion! Our very knowledgeable and personable guide Amy, did a fantastic job explaining everything. Her narrative was informative and well-presented. Lots of room inside the boat, saw many different species of fish and coral. Would highly recommend this tour. We noticed not many people tipped, please consider a tip if you enjoyed the tour, they appreciate it.

Thank you so very much for making our trip to spread my papas ashes memorable. Thank you for videoing it so we will always have the time to look back on. I will definitely be recommending you to everyone I know.

Eden was an excellent guide! Very knowledgeable and fun. Answered all questions and engaged with my kids when they shared their knowledge. Small tour made it feel personal, and great value for money for the time and expertise.

Lots of fun to see fish with my family, some of whom were uncomfortable scuba diving. The crew was friendly and views incredible.

The boat was very clean, and prepped for our ashes-scattering. Amy was very helpful, and responded to questions I e-mailed her either the same day, or the next. She was very informative, telling us where the boat was going to go, how we could scatter the ashes, and telling us about fish we saw through the glass bottom. The captain was able to get us over reefs that were very close to shore, even with strong currents. Great boat, great weather, great crew. I highly recommend it!

Fantastic. This might not be for people who get sea sick easily, as the waves made it super choppy. But we had fun! Also got a small refund (which we didn’t ask for and were pleasantly surprised by) due to poor visibility in some spots. Highly recommend.
