ABC Scuba Diving Port Douglas – Port Douglas’s highest rated dive and snorkel boat on TripAdvisor! Our totally unique operation in Port Douglas makes us the diver’s & snorkeler’s choice. We take just 12 passengers on our day boat tours to the outer reef ensuring you’ll enjoy a very exclusive, individual and private reef experience, visiting stunning outer reef locations teeming with biodiversity. You get to visit pristine parts of the reef in a much more intimate way. Small passenger numbers mean a whole lot more of everything: from personal attention, privacy, time in the water and under the water! Our small dive groups are perfect for those nervous or inexperienced divers.
