Me and my partner had an amazing snorkel trip with Calypso! We had 3 different snorkel sites with around an hour at each one. In between we were provided with drinks and snacks. The buffet style lunch was excellent. The tour was very informative and Kate- the marine biologist did and great job of explaining all about the Great Barrier Reef and its wildlife and was really helpful with the snorkelling aspects- even giving us a reef tour. The highlight was definitely seeing a Minke whale, it came right up to us as we were snorkelling! It was magnificent. What a day

Our experience with Calypso was absolutely incredible from start to finish. The entire boat crew was excellent, going above and beyond to look after everyone and constantly checking in to ensure we were comfortable and doing okay. We felt incredibly safe in the water the entire time, and they provided all the top-notch gear we needed for a seamless day. A huge highlight was having a dedicated marine biologist on board; it was fantastic to learn so much about the coral and the ecosystem, which added so much depth and context to what we were seeing underwater. It was a perfectly run, beautiful day on the water, and I cannot recommend this crew highly enough!

The tour was well-organized and we got to see 3 different areas of pristine coral reef during the day. Lots of fish and beautiful coral, even though it was a cloudy/windy day. The staff were friendly and helpful. The boat itself was a good setup - it had a wide back step for people to ready up their gear before gently immersing themselves in the water. I've done other tours where you're expected to jump off the boat, and this one is definitely not that, which is great! I loved the skipper that was on my boat on Monday, 5/25. She was a pleasant soul to chat with about anything and everything that was outdoors in the area.

A two-hour speedboat ride from Port Douglas. I went to Opal Court. I am very satisfied to have been taken to three very beautiful points in the open ocean. The weather on 5/1 was cloudy and it was cold just to wear a jellyfish-proof suit, so it might be best to have a thin, warm coat inside. By the way, there were no jellyfish!!! The tour staff were all very kind and we enjoyed snorkeling freely.

Amazing experience with Calypso and the whole crew! We visited three different reef sites to see the corals, and we had a guided tour led by a marine biologist who was fantastic at explaining everything. She also helped me a lot when I felt a little nervous about swimming in the ocean. Thanks to her and the entire crew, I had an amazing experience. One of my friends did the scuba diving and had a great experience. He felt very safe and well supported by the guide, who explained everything clearly and made sure he was fully prepared before the dive. Definitely one of the best tours during my visit to Cairns! I would highly recommend it, especially if you’re someone who doesn’t feel very confident swimming in the ocean. The crew makes you feel safe and comfortable, so you can fully enjoy the experience without letting your fears hold you back.

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!
