The experience was fantastic. My guides took us along the reef, we saw plenty of fish and a few sea turtles. I had a great time and am looking forward to the boat dive with Hilo Ocean Adventures.

Amazing Hāmākua Tour
Our guide, Kimo, narrated the tour providing a bit of a history lesson on the history of Hilo, the Bay, the sugar industry, and showed us the local sites along the Hamakua Coast. We even saw a manta ray! Every employee that we came in contact with was super friendly. We had such a wonderful time. I highly recommend!

Awesome Whale-Watching
Captain Kimo runs a tight ship! He’s super knowledgeable and brought water, juice, and snacks for the trip. We started seeing whales less than 20 minutes after departing. It was amazing. Followed the whales for 2 hours and saw a full body breach by an adult humpback. The most exciting thing I’ve ever experienced on this island by far! I highly recommend HOA and I can’t wait to go out with them again.

Great Dive at Turtle Cove
Did a two-tank shore dive at Leleiwi Beach Park with Mark. Great experience! We saw a family of sea turtles. Mark was a true professional - kind yet gave helpful advice when needed - but most of all, he was very patient as I’m new to scuba diving. The shop is very clean and well-organized. They also have an indoor pool to do open-water courses!

Wonderful Snorkeling Trip
Fantastic guides that were all super kind and knowledgeable. They seemed to be just as into the sights as we were! All of us on the boat made for quick friends on what felt like a true adventure. We saw sea turtles and swam with a pod of 100+ spinner dolphins, saw humpback whales, and a hammerhead shark!
