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.

We had a wonderful time snorkeling from the beach, great reef with a couple of turtles too. The guides were very patient and helpful to my friend who had never snorkeled before. Excellent time!

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!

I have been diving for decades and I always see new things but this is the first time I had this experience. I was the only one who signed up for the dive and the company still took me out to dive. They take customer service to a new level. I was greeted like I was family when I walked in the door. I was introduced to my dive master, Matt Leach who had both my tanks ready and was loading thee van to head to the beach. Matt explained the area and the dive with clear precision. He is a fantastic dive master and took great care of me for two dives. He asked me what I was hoping to see before we went in and told me that he might just know where to look. After we were done the staff asked me how my dive went with actual interest. I completely recommend this dive center to anyone who wants to dive, snorkel or even learn to swim. They do it all here and they even have a dive shop to get you what you need or what you forgot to bring!

Swim School

We had a fantastic experience with the swimming class! These toddler swim lessons were excellent! The instructor's approach was not only highly effective but also tailored perfectly for little ones. The focus on water safety, combined with engaging activities, made each lesson both educational and fun. The instructor's patience and encouragement were particularly noteworthy, creating a positive environment for toddlers to build confidence in the water. I highly recommend these swim lessons for toddlers—it's a fantastic introduction to swimming skills in a nurturing setting.
