The trip was good, the staffs on the island are friendly, clear water so can see fews turtles. When we there the water so cold so we snorkeling just a shot time but we enjoyed it.
Reviews: Cairns Sunlover Fitzroy Island 1-day tour [Optional snorkeling/lunch | Emerald Island]

Easy to book with lots of options to suit your needs. We chose the transfer and snorkelling gear package. Just be mindful that you mind have to pick up the gear from other boat before heading to the one that will take you to the island. If you have a big family and kids, it might be problematic to take all of this stuff with you and walk to the boat. The boat was packed and we struggled to find a place to sit with all of this stuff, and had to seat separately. Apart from that the experience was great, the island is beautiful and you can see the reef and all the sea life. The beach itself is covered in washed away corals, which is beautiful but you might need coral shoes or crocs to make it easier to walk. You can also hike up the mountain or Nudey beach and the view and water is stunning. The food and water are pricey but you take take it with you from land.
