We had a fantastic day out to the Opal reef. The crew were friendly, knowledgeable and very hospitable. Morning tea, lunch and afternoon tea were great. The 3 sites we went to were amazing with great coral diversity, definitely some of the best snorkeling I’ve done

Great boat and even better crew to keep you safe. Unfortunately, the day we went the wind had picked up and the sea was very rough. This impacted our ability to fully enjoy the sites while snorkeling.

Absolutely fantastic day out on the water! The crew worked tirelessly to ensure the safety & comfort of all onboard while under motor & while in the water. The Barrier was absolutely stunning to see in person, highlights of the day were seeing a reef shark beneath us & the hot Milo after our last swim to warm up. Outstanding team!

Victoria and Allison were fantastic. They took excellent care of my wife and I. Very patient teaching us to dive. Excellent communicators. The trip of our lives was made even better.

It's a lovely day out on the water. Make sure to get your coffee or tea before the boat leaves the dock then sit back and relax, it's a bit of a ride to the first stop. Lunch was great, simple but hardy. My only pick is that during the 3rd swim the guy who was supposed to be watching the snorkelers on the upper deck was on his phone. Thankfully, there were others watching as well.

Fantastic day. We went to Opal Reef, and had an hour at each of three seperate locations. They were progressively better, all great but the third mind-blowing. The crew were super nice and professional. A very decent lunch was provided. 12/10!

Even though the weather was not ideal (think big swell, lots of wind), the crew made sure everyone had a good day. The reef itself is incredible and should be seen by everyone at least once.

The staff was amazing, attentive, and focused on safety and fun. A+ The snorkeling was also outstanding. Lunch, drinks, cookies on board delightful. Loved it. Weather wasn't good, bit no one can affect that. Memorable experience and would recommend this cruise and boat.

The trip was a little bit underwhelming for an experienced snorkeler. The problem with the tour was they tried to combine first time, scuba divers with snorkelers, and they only stayed on one reef, which was the opal reef- when I thought we were going to another larger reef never saw any turtles or Rays, the Coral was beautiful but to do it two times and two different places on athe same reef just so we could accommodate depth for-the scuba divers, the snorkeler got to see basically the same thing they saw on the first part of Opal reeff Probably should have booked out of Cairns.
