Simon and Kiwani were wonderful. We had a fun and comfortable boat ride in the morning, and we were lucky to have spotted humpback whale with her pup on the way out, and dolphins as we were at the Kealakua Bay as well as on our way back. Simon knows the bay so well and exactly where to take the group to for sight seeing. Snorkeling at the Kealakua Bay was fantastic with so many different sea creature in clear blue crisp water. Very happy with the tour and would def sail with them again!

An amazing experience for sure, we were very lucky and saw 2 types of dolphins on our way to the bay for snorkeling. And kealakekua bay is definitely worth it’s world famous reputation. There were so many types of fish and corals, it was a bucket list item we had to do fire sure. Also, Captain Jacob and the crew (Jonah and Kiyomi) are really friendly and helpful, and knows a lot about the island, the history and the surrounding area. Highly recommend!

We loved going to the Captain Cook monument to snorkel! The experience was incredible! We’ve never seen a wild reef before and it was amazing! Bring a water proof camera or get a water proof case for your phone to take pictures. The only downside was we got back to the marina a whole hour early for some reason. It was like they weren’t keeping track of the time for us. We could have snorkeled longer. But this is a must-do on any Hawaii trip! You won’t regret it!
