Brief History of the Kona Glass Bottom Boat Tour

The Kona Glass Bottom Boat Tour is one of the top things to do in Kona with kids.

The boat is called the “Marian” and it was built in the 1990s by the founder Captain Ralph and Jeannie Jewel.

The Kona Glass Bottom Boat Tour uses a fleet of specially designed boats that feature large, clear viewing panels in the hull and comfortable seating for passengers.

Over the years, the tour has become a beloved Kona coast attraction, drawing visitors from around the world who are eager to experience the natural beauty of Hawaii’s underwater world in a unique and unforgettable way.

What to Know about the Kona Glass Bottom Boat Tour Before You Go:


We were already staying at the Courtyard by Marriott King Kamehameha’s Kona Beach Hotel, so it was a short walk out to the pier.

We stood in line for a couple of minutes before boarding the boat.

We happened to go during a mild storm so it was a bit rainy and the boat was rocking a LOT when we entered.

Our tour guide offered everyone ginger chews and ginger ale, which helped immensely.

Kona Glass Bottom Boat Ride

The boat ride itself is about 45 minutes long. It goes around the bay near the Courtyard by Marriott King Kamehameha’s Kona Beach Hotel.

Our captain moved pretty quickly and got us to several different spots that are popular fish-feeding grounds. This means we got to see a TON of tropical fish.

During this Kona glassbottom boat ride, our tour guide told us a bit about Hawaiian history and cultural traditions.

She also told us fun facts like where boogie boarding was invented. Hint: you can see the beach from the boat!

At the end of the Kona boat tour, we docked back at the marina and climbed off the boat. Check the latest rates and availability.

The Highlight of this Kona Tour and What You Should Look Out For

I mean, seeing tropical fish in a coral reef without going snorkeling is pretty amazing. My 9-year-old kept geeking out over spotting fish and repeatedly said it was a cool tour.

The large windows are perfect for getting a great look at the ocean floor and identifying all types of Hawaiian fish.

The waters off the Kona coast are teeming with hundreds of species of tropical fish, including angelfish, triggerfish, and butterflyfish.

Green sea turtles are a common sight on the Kona Glass Bottom Boat Tour, and passengers often have the opportunity to see them up close as they swim along the ocean floor.

Insider tip: I suggest looking out the window when the boat is moving quickly to get to each stop. There isn’t much to see during that time and it can exacerbate seasickness.

Tips for Families

If you’re planning to do the Kona Glass Bottom Boat Tour, here are some tips to help make the most of your experience:

Dress Comfortably

The tour is conducted in an open-air boat, so it’s important to dress appropriately for the weather. Sunscreen, hats, and sunglasses are also recommended.

We went in February and wore long pants, closed-toe shoes, and sweatshirts and we were comfortable.

Arrive Early

The Kona Glass Bottom Boat Tour is a popular attraction, especially during peak tourist season, so it’s a good idea to arrive early to avoid long lines and ensure a good seat.

We were some of the last people to board and we ended up having to squeeze in with 2 other families. Had we gotten in line earlier, we might have had more room.

Bring a Camera

The marine life you’ll see on the tour is truly spectacular, so make sure to bring a camera or smartphone to capture some amazing photos.

You might even want to bring a portable battery charger if you think you’ll be taking lots of video (which I did).

Listen to the Guide

The tour guides are knowledgeable and experienced, and they’ll provide valuable insights into the marine life and history of the area. Be sure to listen to their commentary and ask questions if you have them.

If your family has gone snorkeling on the Big Island, you can also ask them to help you identify any sea life you saw.

Be Prepared for a Little Bit of Motion Sickness

If you’re prone to motion sickness, be sure to take appropriate measures such as taking medication or sitting in the middle of the boat to minimize any discomfort.

We went during a mild storm and the boat was ROCKING. Many of us had to look out the window so we didn’t get sick.

By following these tips, you’ll be sure to have a memorable and enjoyable Kona Glass Bottom Boat Tour experience.

Typically, people don’t get seasick on this Kona boat ride, however, it’s always a possibility. What’s good about this tour is that it’s only 45 minutes long, so you won’t have to suffer too long.

Is this tour wheelchair-accessible?
