Reviews: Calypso Outer Great Barrier Reef Cruise from Port Douglas

Guest User2024-06-21

We had THE BEST DAY on our Family Calypso Reef Snorkelling Cruise (from Port Douglas). The crew onboard Calypso Blue on Thursday 20/6/2024 were amazing, so professional and so friendly. They made us feel very welcomed and put those that were nervous at ease, re-assuring everyone that they are there to look after us. Food and snacks were nice and simple. We chose to go with Calypso as it came highly recommended on the web (through reviews) plus a big draw card for us was that they only took a small group of people on board the tour at anyone time. It was a whole day cruise, where we stopped at 3 different locations on the Great Barrier Reef to snorkel. It took about an hour to get to the reef. Each different stop on the reef was about an hour. It was so beautiful and so special for us as a family to finally experience the Great Barrier Reef. There were so many beautiful corals, so many colourful fish and in all shapes and sizes. The ocean was so clear too. The staff on Calypso Blue were very knowledgeable and educated us on the reef and how we can do our part to help look after it. We had the BEST DAY and will remember it for a long, long time. A big thank you to the crew on Calypso Blue for making it happen.
