Return Details

Returns to original departure point
Dive into the magical underwater world of Hawaii without ever leaving the boat during this ride aboard a glass-bottomed vessel. This special ship offers a unique window into the wondrous mysteries and fascinating creatures that inhabit the Big Island’s shores and reefs.

Check in for your morning boat ride at Kailua Pier, climbing down into the viewing area of your totally custom-built 36-foot (10-meter) boat. Grab a seat on a cushioned couch alongside one of the boat’s four viewing windows and receive an introduction and overview of your trip from your on-board naturalist.

Cruise out into the mellow waters just off the Big Island as you admire some of this amazing coastline’s unique coral reefs. Your unique shallow-bottom boat can get right up to the edge of these amazing underwater wildlife areas, offering you the perfect view. As you gaze in amazement at the colorful fish and corals below, listen as your naturalist narrator shares a few insights into reefs and the ecological forces that shape them. Learn where some of Hawaii’s beautiful white sand comes from and get a peek “behind the curtain” of fish mating rituals.

Continue your ride by proceeding into deeper waters, allowing you views of an amazing underwater pinnacle and a chance to watch as the bottom quickly drops off into the deep ocean. As you ride, you might even have the chance to spot spinner dolphins and (depending on the season) humpback whales. And if you get tired for some reason of the views from below, turn your gaze toward the horizon, where you’ll be able to spot historic shoreline sights like Hulihee Palace, Mokuaikaua Church and Kamakahonu (where King Kamehameha I made his home in his final years), plus much more.

Finish your magical experience along Hawaii’s beautiful coast by traveling back to Kailua Pier.

Not many fish

Disappointed didn’t see many fish there were going a few fish, coral was pretty., very sad about lack of fish.
icon Response from Host , Nov 2021
Sorry to hear that you were disappointed by the number of fish. We tour a natural coral reef ecosystem with fish in numbers that is appropriate for the health and well being of the coral and all the reef inhabitants. I understand that you may have expected more fish as movies and such can sometimes give folks the idea there may be very large numbers of fish. Mahalo for taking the time to review our tour.

Informative and very interesting tour. Can see everything you would see if you went snorkeling without getting wet. Great for mobility challenged folks.
icon Response from Host , Oct 2021
My thoughts exactly, see the underwater world without getting wet! We are happy to offer a chance for people with mobility issues to enjoy the underwater world. However, we are not completely handicap accessible for those in a wheal chair. I encourage folks with mobility issues to look at the pictures and video on our website to see our boarding ramp and stairs to determine if it is something they are comfortable with. Mahalo!
Highly recommend. Great for kids too.
, Oct 2021
Eden did a great job in her commentary during the trip. She gave a history of the island and reefs and was very informative on what we got to see above and below the water. The under water views were amazing! It’s a short trip and would love for it to have been longer but very much enjoyed the whole trip.

Mahalo for the wonderful review. We are glad to know that you enjoyed the commentary and the underwater views. Thank you for the input on the duration of the tour. Aloha!

Sea sick
, Aug 2021
The experience of looking at the coral through the glass bottom is very cool, but everyone in our group of 11 got so sea sick that it just wasn’t enjoyable. Would not do again.
icon Response from Host , Aug 2021
We are so sorry to hear that your group got seasick. It is quite unusual to have everyone in a group get seasick. Generally, folks do fine, however for those of that are prone to motion sickness we encourage them to take precautions. We do not operate our tour if the conditions are too rough. But, just like any boat, some people may get sick. So glad that you enjoyed seeing the sea life through the glass.
