Our Great Barrier Reef tour was an amazing, once-in-a-lifetime experience with a fantastic, friendly crew who kept us fueled with regular, tasty snacks. The reef itself was breathtaking, and we loved seeing it from every angle by both snorkeling and taking the glass-bottom boat. A huge special shout-out to Maddie, who was incredible with my husband; he isn't the most confident swimmer, but she helped him feel completely comfortable and at ease in the water so he could fully enjoy the experience. It was a brilliant day from start to finish, and we would 100% recommend this tour to everyone!

We had a fabulous day on our Ocean Freedom Great Barrier Reef snorkelling day. The crew were friendly, informative and professional. We were a small group of 21 and everyone was catered for - from snorkelling novices to experienced divers. The reef and wildlife were spectacular. Food was good quality and plentiful and we were surprised with snacks throughout the trip. Tea and coffee was available all day. It was definitely value for money.

Just a fantastic experience all-around. Ollie was a superb dive instructor, working the equipment for me and helping me identify some awesome animal life. Snorkeling was also great, even in the strong current. Everything was on time, everyone was efficient and kind, and the equipment was all top-of-the-line (with prescription masks!).

The staff were all fantastic and the first snorkel location was amazing. The second location was just okay but still overall amazing compared to the shorter day trips to nearby islands. Lunch was tasty and had something for everyone. Drinks you have to purchase. The Lycra suits stunk when given out but the rest of the equipment was fine.

The boat and crew were amazing! So helpful, patient and friendly. Multiple times throughout the experience they checked on folks to make sure we were ok. They advised sea sickness pills because of rough seas and admitted they also took them, which i find endearing. The snorkeling was rough and not ideal. A storm went through the area several days earlier causing the water to be cloudy. Also, the water was very choppy with 4 (??) Foot waves. I say 4 for because that's how big they looked when I was in the water. So it was a battle to stay in one spot to see stuff. I think most folks stopped snorkeling before they typically would have because of the choppy water. Because of the water, the crew gave small group guides tours instead of free snorkeling for safety reasons. Completely understandable, but that meant a bunch of folks in a small location all at once. I got kicked in the face several times and I know I hit others as well. It is strongly advised you wear a lycra suit because of sun protection and jellyfish. I do wish they would have been more clear about that as a long sleeve swim shirt and pants would have worked and i could have brought my own to be more comfortable. They provided breakfast, lunch and several afternoon snacks. Everything was delicious! There was fruit, cheese and crackers, pasta, shrimp, chicken and cake throughout the day. We had a great time! I would definitely recommend this tour Ocean Freedom to anybody. They did a wonderful job making sure we had a great a time as possible. There wasn't anything the crew could have done to make the trip better! Thank you!

We booked this experience with 2 young children and I cannot thank the crew enough for how helpful and friendly they all were. The captain even ensured our children got a set of cards to look at with all the fish they could potentially see. The organisation of all the equipment for snorkelling was very professional and ensured everyone knew exactly what equipment size they were before even getting to the reef. We had some rough weather and both children and myself were sea sick, the crew looked after us all very well, with drinks, and checking on us. When we got to the reef, they took our children out on an organised snorkel tour to show them around and support with the rough seas, they both really enjoyed this. The food provided was also very good, from the fruit and pastry on arrival to the lunch time buffet and afternoon cake on the way back. If you are looking to do a reef cruise, the Ocean Freedom team is the one to go with.
