Itinerary Breakdown: What Makes Each Stop Special?

Stop 1: Check-in and Departure

Once aboard, your crew sets the tone with friendly professionalism, providing you with snorkeling gear, wetsuits or stinger suits (seasonal), and buoyancy aids, making safety and comfort a priority right from the start.
Stop 2: Michaelmas Cay – 2 Hours
This uninhabited coral cay is the first stop, about 22 nautical miles from Cairns — roughly the same distance as crossing the English Channel. Its reputation as the largest of Cairns’ uninhabited coral cays makes it a stunning location for snorkeling. The reviews rave about the marine life here, with many mentioning schools of colorful fish, turtles, and vibrant corals. One guest noted, “We saw many fishes and the ocean was fantastic!”
The guided snorkel tour here is a highlight, especially with guides that help even non-swimmers feel confident. The shallow waters are ideal for families or travelers who want to stay close to the surface, soaking in the sights. The island itself is a peaceful spot to relax, even if you prefer sunbathing or a casual walk along the beach.
Stop 3: Hastings Reef – 2 Hours
The second location is Hastings Reef, about 30 nautical miles out. Known for its lively coral formations and abundant marine life, Hastings offers a different landscape than Michaelmas Cay. One reviewer remarked on the “fantastic snorkeling spots,” with some spotting large parrotfish and other colorful reef dwellers.
This site is perfect for those who want to see a variety of corals and fish species, with some reviews mentioning turtles and the opportunity to explore crevices and overhangs. The boat moors close to the reef, with the guide in the water providing valuable insights about the different species, which enhances the experience significantly.
The Glass-Bottom Boat Experience
Throughout the day, you can also enjoy the glass-bottomed boat, offering a non-swimmer-friendly way to view the reef’s underwater spectacle from above. Many reviews highlight how guides make this tour informative and engaging, adding value for travelers who prefer dry land or want a second perspective on the marine environment.
Return and Reflection
After the reef visits, the boat takes you back to Cairns around 4 pm. There’s plenty of time to relax, chat, and enjoy the buffet lunch and teas—which many reviewers mention as being plentiful and tasty. The amenities are clean and accessible, and crew members are attentive, ensuring everyone’s needs are met.

The food and beverages are another highlight. “Lunch was delicious, and there was plenty of it,” mentions a reviewer, emphasizing the value of having a well-prepared buffet after several hours in the water. Morning and afternoon teas keep you energized without feeling heavy.
Considering the Value: Is It Worth the Price?
At around $179.67, this tour delivers a comprehensive reef experience, especially considering the inclusions—snorkeling gear, wetsuits, guided tours, and a buffet meal. Comparatively, many similar tours might cost more but offer less personalized service or fewer stops.
