Must Do While In Kona!

Took my mom and daughter for a birthday excursion (daughter eight years old) and the experience could not have been better. Kris and Elayo were fabulous! I recommend this excursion with this team to anyone who wants an exceptional snorkeling experience paired with thoughtful snacks and kind, informative conversation.

An excursion that's worth the hassles.

Eric & Lucas, the snorkeling & sights, and the pineapples made this excursion so much worth the trip!! Check in was quite confusing because I was given 2 addresses! Tip: read the instructions attached to your barcode ticket and pay attention to the outfitter who is providing the excursion! Kona Snorkel Tours provided excellent service once you are able to find "their spot." BUT once you get on the Zodiac boat and to your snorkeling destination, everything was smooth sailing. Good job, Eric & Lucas! The sea caves were nice, could be better with story-telling. Definitely 100% recommended, just be aware of the limitations.

The Zodiac was a great ride. We saw whales, dophines, and sharks. Our Captain Gabe was very willing to share his history and love of the sea. Liz is also a great tour guide. We had plenty of time to snorkel a Captain Cooks memorial. I recommend this tour.

A Night to Remember: Manta Rays, Sunsets, and Stars on the Big Island

What an absolutely unforgettable experience! Our manta ray excursion with Kris, Mary, and Ty was one of a kind — this is something everyone needs to experience at least once, and you want to do it with this crew specifically. They were exceptional hosts, and you could tell they're genuinely passionate about what they do, not just going through the motions. The boat ride out was stunning on its own — watching the sunset as we made our way to the manta spot was a must-see moment before the main event even started. And then the mantas actually showed up! Getting to see them up close was pure magic. The ride back to the dock was just as memorable — under a dark sky blanketed with stars and the moon, it felt like the perfect end to an already amazing night. We'll definitely be booking with Kris, Mary, and Ty again next time we're on the Big Island. Can't recommend them enough. I actually shared with a family I met on the beach today and hope they do it before they leave. I can’t stop talking about it🤗❤️❤️❤️

Super Special Experience ❤️

Others in group can destroy experience if they're not comfortable in water. Thank goodness we had an awesome group of compliant participants. These gentle giants will come within inches of you if you stay calm, relaxed, and lay flat. Camera is a must for this experience of a lifetime.

Two Reef Snorkel Trip-See Captain Cook Monument & Sea Caves

Martin_H, Jun 2026

Awesome fast but comfortable trip to two snorkeling spots

Experienced captain and crew. Polite and informative and professional. We preferred the quick run this company’s boats make to the places of interest, and going close inshore to see some features. Being one of the first boats to arrive at Capt Cook before the mega catamarans and passengers arrive is a plus. And later continuing on to the virtually deserted and more rugged area off Two Step beach was a big plus.

Kona’s Best Morning Snorkel: Captain Cook & Kealakekua Bay

Christina_A, Jun 2026

Excellent experience and wonderful staff!

We had a great time on this tour! We had plenty of time to snorkel and relax in the water. Easy to get in the water and loved having tubes. Worth every penny! Other boats did not look as fun as this one. The food was good but just wish we could’ve had some non plant based options. However, I would still book again. Highly recommend!!

We had a great time

This was a wonderful experience. The boat, with its slide and jumping platform was nice, and the crew were friendly and attentive. The area they took us to snorkel and swim was beautiful and there was a lot of fish and coral to view. The breakfast and lunch was adequate and of good quality. We did not see a dolphin, but everything else was great!

Relaxing Boat Tour - Professional, Family Friendly, Great for Beginners

Kona Style is a super professional, well run outfit with warm, friendly service and great guides. The boat is extremely comfortable and a super chill way to see the island from the water, experience the sealife (dolphins, whales if you're lucky, and of course the fish and coral at the snorkeling stop). Lunch is yummy, you are treated so kindly on the boat, and one of the guides gets in the water to help with anyone who needs an extra hand getting used to snorkeling. Check in is super easy to find and convenient at the hotel location by the pool, and the Uulani's Shave Ice right next door couldn't taste better than right off the boat. My only comment would be if your highest priority is snorkeling, the time in the water for me felt a little shorter than I would have preferred, but I am an avid snorkeler and had been on a smaller boat tour the day before (that was not at all comfortable or chill) but I felt like I got my snorkeling fix. I liked having two tours to experience the water in different ways, so I would just think through what your priorities are for your tours to make sure you are picking the right one for you. If you want an enjoyable boat ride and snorkeling at one of the best places in Hawaii, you won't be disappointed.
