Absolutely incredible day, really enjoyed going to 2 different sites! The guides were incredible, full of knowledge and just all round beautiful people! We loved the indigenous cultural presentations and performances! Yummy cold lunch and snacks as well! Can’t fault the day.

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

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.
