What do others think of Ocean Eco Tours?

"We just did the Open Ocean Safari with Ocean Eco Tours for the second time, and it was even more amazing than we remembered! Monet and Brendan are both incredible. They are knowledgeable about the ocean and the wildlife, but what really stood out to us was how genuinely passionate they are about what they do. They have the best energy and made the whole experience feel so fun and personal.

You can tell they truly care about the ocean and love sharing it with people. We learned so much, felt safe, had an amazing time, and saw some incredible animals including Pilot Whales. This has become our Kona must do while visiting!!"

- Katherine B.
"Monet and Branden were amazing and very accommodating even for a non-swimmer. I highly recommend this tour without hesitation."

- Marco G.
"Fantastic experience. Perfectly organized and shared in a small group. The guys are a young couple passionate about the ocean who enjoy explaining and taking care of their boat. Unlike other tours, they are more respectful of the animals with precise instructions on how to behave. Highly recommended."

- Elena C.
"We had a wonderful time on our Ocean Safari! We were able to see bottlenose dolphins and false killer whales on our trip! Monet and Brendan made our time special with their kindness and extensive knowledge of the marine life we could encounter. Would 100% recommend to anyone visiting the Big Island."

- Laynie G.
"This was by far one of the best days I’ve had in Hawaii. Monet and Brenden were so chill, but so professional and great ocean stewards, and knew exactly where to find all the dolphins!"

- Ryan T.
"We had the best time! We saw three species of dolphins, and got to swim with two of them. Expert guides (s/o Monet, Brendon), thoughtful service, and amazing vibes. 11/10 recommend."

- Austin V.
"Definitely a bucket list experience. We saw several rays feeding and barrel rolling – they got SO CLOSE. Monet and Brendan were so sweet. Monet knew the names of several of the rays we saw and Brendan knew just where to find them. Thanks, guys. It was so so fun."

- Lauren P.
"The manta ray tour was so fun!! it was a smooth boat ride to the place and back. we got to see many mantas near us, it was truly a spectacle!!"

- Samantha P.
"I cannot recommend ocean eco tours enough!!!! We did the manta night snorkel and from start to finish it was a lovely adventure! Monet was incredibly kind to all the guests and really made us feel welcomed! We started the trip out to where the mantas were with a beautiful sunset and got to see so many mantas in a fun and safe way. The whole excursion was genuinely breathtaking and left us in awe! Thank you Ocean Eco Tours for a once in a lifetime experience and great memories!!!"
