Do NOT book this tour! I just returned home (California) after vacationing on the Big Island and I am finally able to write a review about this tour. This tour was billed as "Dolphin Encounter and Kealakekua Bay Reef Snorkel" and it ended up being quite the OPPOSITE. After leaving the harbor, the first part of the tour was dedicated to finding dolphins. Upon seeing some on the surface at a distance, the guests then entered the water for their "encounter". Some people did see dolphins (way down beneath them) and some saw none, including me. After that disappointment the boat crew then pointed the boat north instead of south toward the Capt. Cook/Kealakekua Bay area. I asked one of the crew why we were going north instead of south and reminded him that this tour is billed as going to Kealakekua Bay. He replied that, "Kealakekua Bay is way overrated and there are too many other people there so we're going to a different area." To me, that's like being on a flight to San Francisco and during the flight the pilot comes on and says, "Ladies and gentlemen, I think San Francisco is overrated as a destination so we're going to Portland, Oregon instead." The crew then put the boat into one of their "preferred" snorkel areas which actually had fewer fish than the beach parks along Ali'i Drive in the Kona area. This tour ended up being one of the most disappointing experiences in my life. I repeat, DO NOT TAKE THIS TOUR!
