We did the half day kayak trek out to the Captain Cook monument, then snorkeled for about an hour and a quarter. The Aloha team was very professional, everything was on time, the equipment was good. We enjoyed our guide, Rabbit - he gave us quite a history lesson on Captain Cook, as well as other interesting information about the geography and history. It's not a cheap trip, but it seemed a good value to us. We are fairly novice kayakers and snorkelers, so this trip was a good fit for us, and Aloha was a good choice.
