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!

I'd like to give the whole experience 4.5 stars only because there was confusion about where to meet the boat and her terrific crew - a discrepancy that wasn't too difficult to figure out - a tweak on that would be helpful to some. Beyond that, the activity was outstanding. Simon and Aidan's knowledge, skill & humor along with Kauani's (sp?) welcoming smile & diligent monitoring of our group's needs showed their considerable experience with the Kealakekua tour. They could not (of course) compete with the wildlife we saw along the way - the spinner & bottlenose dolphins, white tropicbirds and diversity of fishes and corals in the bay itself. Snorkeling was done in the cove near Cook's monument, and though there were a lot of snorkelers, people were courteous and did exercise care, staying off the corals and snorkeling at the surface. Simon was careful to avoid disturbing the animals we saw; we appreciated how trash was monitored carefully so as not to get into the bay. Great trip!

Super fun boat tour with a cool crew of three. We were the only boat in the bay. Unfortunately there were no dolphins, but you have no influence on that. In addition to cool drinks, there were also snacks on the trip, and sandwiches were served in the bay for lunch. On the way back we drove closer to the coastline and this was explained and we even got to see a pair of manta rays. Great excursion!
