Slide into the alluring Pacific Ocean, buoyed by our light board accompanied by our dive guide to witness the majestic manta rays come to fee on the abundant buffet of phytoplankton that appears with the glow of underwater dive lights. Experience the thrill of having giant manta rays gracefully glide and swoop through the waters... all within inches of you.

We wanted to thank Owner Bambi & Capt Keith for a Beautiful & exciting day of Snorkeling ,Site Seeing and Learning the History of the Kona Coast ....We found Dolphins in Kailua Bay and we're instructed as to how to approach them in the water so as not to scare away .....This was one for the Bucket List !! We also were taken to Kealakekua Bay and had the opportunity to swim and snorkel with an abundance of tropical fish ..... Definitely a 10 !! We enjoyed the day so much that we booked with them for an evening Manta trip next week .....Thank You for the Highlight of our Vacation ❤️

I have been out with this company several times in the past few months. One of the many things I like is that they share the history of the region, and help one to understand and respect the ocean life. I've never had an unsatisfying experience.

"Too expensive for what you get."

This was a very high-priced provider when compared to other companies. They have a 6-person zodiac boat, so they claim to offer a more personal experience. Well, my experience was that our boat captain would not shut up about his experience on other boats, and all of the people that he knew on the island, and how we should visit his coffee farm. He, seriously, NEVER STOPPED TALKING. It was exhausting. AND, we NEVER got to swim with the dolphins, because we could not find any. Then, when I asked about a discount on another trip to try again to swim with dolphins, I was offer $20 off. Seriously? This company already charges $30-$40 more per person. Ridiculous! I understand you can't control wild animals. But, you can control the captains that you hire, and the discounts that you offer people for returning after disappointing trips. Go with another company. Complete waste of $340!

We did the sunset tour. Captain was knowledgeable. We saw two manta Ray's and a bunch of maquerel fish eating the plankton. Cool experience with no feeding from.human to the wildlife which is good!
