Amazing experience - The service is professional and friendly. Glass bottom boat was an amazing experience. Snorkeling in waters surrounding the green island is so cool. Next time I’ll probably do the diving too.

Must see in Cairns - Had an amazing day on green island the little crocodile zoo they have on there is a good visit didn't get to explore the island too much since I only had 3 hours but the glass floor boat tour and the zoo made it a very fun day. Will definitely go back next time.

Amazing - Fantastic day on the island. All at your own pace. Explore the crocs, it’s worth it then hopefully swim with a turtle. I did.

The amount of rain limited the activities - This is an awesome trip - just wish it hadn’t rained so much! People were still able to snorkel and the glass bottom boats were a good experience. Staff were very professional

A bit expensive;... - A bit expensive; additional costs during day eg lunch was expensive. Tour guides were overall nice and friendly but ours missed us out on the boat (before getting to Green Island)- she also assumed I couldn’t speak English (very surprised)! Otherwise glass bottom boat trip was very good and worthwhile.

Way to short - Time on the boat was very short. Excluding loading and unloading, we spent just over 20 minutes looking at/for fish and turtles. Captain was knowledgeable and helpful. We did see quite a few fish. There is too much light coming from the sides of the boat reflecting off the glass floor to be able to take good photos.
