Reviews: Great Barrier Reef Full Day Tour from Cairns

Guest User2024-09-15

Wife enjoyed the snorkling on the reef .It was her first time. I've done this before ,and in New Caledonia, and Samoa. I think the company could offer a reduced cost for passanger only accompanying a diver as wife wouldn't go by herself . And as couple not both partners want to dive.

The places in the reef that were chosen were absolutely breathtaking! It was like swimming in an aquarium there were so many fish. The coral Was stunning and diverse. A very competent crew and skipper Makayla!! Recommend this small group tour over the larger groups for sure!!!

Reviews: Full-Day Great Barrier Reef Snorkeling from Hamilton Island

Guest User2025-09-02

Had a fantastic day ,very lucky with weather very smooth trip no wind ,you do 2 snorkel sessions of 1 hour each,the crew were very good and helpful, would definitely go again. We did the other day trip the day after this to Whitehaven beach including the snorkelling experience combined and due to the windy conditions the trip that day was cancelled to the barrier reef and the people from there then joined our excursion. So weather permitting this is a fantastic excursion.
