Big Island: Manta Ray Night Snorkeling Adventure in Kailua-Kona

Great Experience & Well-Run Tour!
This tour was extremely well-run. Our tour guides (Kelly & Kala’e) were extremely nice, funny, & professional. Everyone met up at the meeting-point in the harbor, check-in was fast and easy, and then you were given a jacket wetsuit and snorkel gear. (You could also bring your own wetsuit and snorkel if you prefer). It was about a 20 minute boat ride to the manta ray spot, and drinks/snacks were provided (water, sprite, chips, granola bars). At the manta ray spot, we got about 30-45 minutes in the water. One guide stayed in the boat and the other was in the water to give fun facts and help anyone swim. You hold onto a bar as the manta rays come up to feed (my arms did get tired). Everyone also got a pool noodle to help keep their legs afloat. You could go back to the boat at any time. We saw about 5 manta rays, and they came super close to you as the fed. There was also an option to just stay in the boat the whole time as a ride-along. Overall, I thought this tour was extremely well run, super cool, and well worth the money. Would definitely recommend!

Loved the Tour and the Snorkeling!
We had such a great time on this snorkeling tour. Aiden was our guide and we couldn't have hoped for anyone better. Very knowledgeable about boating, the area, the culture, and everything we were there to see, plus he has a great sense of humor! Snorkeling at Kealakekua Bay was as great as the literature says it is.After snorkeling, we were served yummy sandwiches and chips.

Cool Hawaii screwed up but the tour company made it right.
Booked with Cool Hawaii but Cool Hawaii wasnt supposed to book it for that day because the boat was in for maintenance. So we showed up and nobody was there. The tour company immediately made it right even offered to have someone come meet us and bring snorkel equipment and recommended a good snorkel spot. We ended up doing the tour a couple of days later. Eric and Lucas were great. Eric seemed to have as much fun driving the boat as we did riding on it. We saw a couple of pods of dolphins on the trip to snorkel. Captain Cook monument was a great place to snorkel water was very calm and there was alot of fish. Lucas cut up delicous pineapple for everyone. Saw some sea caves and historical sites on the return trip. Would definitely recommend this tour.

Good experience, nice people
That’s definitely the experience that is worth the visit. The experience is the same like the other companies, just better price. The crew was awesome, Trevor and the other two guys had a great sense of humor and were pretty helpful of giving us more info about the island and everything we should know.

Pick This One!
Great crew and boat. This boat has a roof over the seating, providing shade when the sun is beating down as well as a flush toilet on board! Snorkel gear was in great condition. Lunch consisted of nice sandwiches and fresh pineapple. Snacks and beverages were available throughout the day. Most importantly, saw a variety of fish while snorkeling. Crew also took photos of us for us.

Amazing tour! Smooth check-in and -out and professional crews. Big shout out to Deavon, Koa, Kanana and Greg who kept us safe and made the tour enjoyable. We saw four mantas, they were so close to us (don’t touch them). Still feel surreal, an unforgettable experience.

2 Hour Big Island Reef Snorkel & Dolphin Watch Tour

Family Snorkel
One of the top experiences we wanted to do on our trip was to go snorkeling. We had a party of 7 and chose to go on a 2 pm start time. The staff was pretty friendly. We got to see some dolphins on our ride to the snorkeling area. The boat ride was pretty short and we had a lovely view. As we were snorkeling our guides were very attentive to make sure we didn't need help with mask or any other problems. The water was so clear and we got to see lots of different types of fish. I wish we had a go pro to take pictures underwater. One of the family was timid on joining us in the water as this was their first time. One of the guides was able to ease their mind and they soon joined in as well. Overall I would book again given the chance.

This was so fun snorkeling where the inspiration from “Finding Nemo” is from. Seeing the beautiful marine life and our captain was so informative and helpful. He made a few stops to tell us some history we even got to see the “Pele Goddess” that inspired Moana. They even had fresh pineapple it was delicious!
