ABC Snorkel Charters are the highest rated Port Douglas snorkel operator on TripAdvisor. By restricting our daily passenger numbers to just 10 guests, we can provide a whole lot more of everything. From personal attention, to privacy, time in the water and outstanding customer service. Our tiny snorkel groups are far superior for observation and ensure a much more personal experience. ABC offers the highest staff to passenger ratio. Giving you the amazing chance to ask questions about what you are observing, pointing out the more unusual creatures that are generally missed by the untrained eye.
