Wet and windy

While we visited on a wet windy day, we were still able to enjoy our glass bottom boat trip and island walks.

Turtle Power!

It was a lousy day weather wise but we still had a great time. Lovely to walk around the island and the glass bottom boat did not disappoint......I have wanted to do this since I was a child. We did not visit the crocodile exhibit as we felt the cost was extreme.

Operator response

This was a nice...

This was a nice experience, not outstanding. It is very family-friendly, low key, with a range of available activities. The glass-bottom boat ride was about 15 minutes and there wasn't a lot to see in the green, mostly murky water (we also had poor weather). Technically, I was able to snorkel in The Heat Barrier Reef, but only in very shallow, restricted waters near Green Island. There were some colorful tropical fish and one awesome sea turtle, but not much in the way of the beautiful bright coral associated with the reef.

Green Island -

Great experiemce.. only the Emerald restaurant on Green Island the staff were rude and terrible with service. We actually wanted to hangback and have a few drinks but the person there said that they needed the table for paying guests. We ordered meals for the family so unsure why they wanted us out.

Operator response

We appreciate you taking the time to let us know, and hope to welcome you again for a smoother experience in the future.

Green island for a family of 4

We had a fantastic day trip to Green Island. The boat ride took around 40 minutes, and once we arrived we grabbed our snorkel gear and hired a couple of beach chairs before heading into the water. We also hired a GoPro to video our in and out water experience. The snorkeling was excellent—we were lucky enough to see a turtle, and the marine life was abundant both in and out of the water. While the coral wasn’t the best we’ve seen, the wildlife more than made up for it. The island is small but has all the facilities you need for a relaxing day. We travelled with our kids (aged 10 and 11), and they had just an amazing time. We’d definitely come back and would happily recommend it to other families.

Operator response

Thank you for sharing your experience on your Green Island day trip with Great Adventures. We’re really pleased to hear you and your family had such a great day, and that the kids especially enjoyed it. It’s wonderful that you were able to make the most of the snorkelling, hire equipment, and capture your experience on the GoPro. Seeing a turtle is always a special moment, and we’re glad the marine life both in and out of the water helped make the day memorable. We appreciate your honest feedback on the coral as well, and are happy the overall experience still delivered a relaxing family day out.

An average outing

Seeing the coral and fish from the glass bottom boat was great. Green Island is not much of a place. The food outlets are a bit grungy. So we were glad to finally make the return journey back to Cairns. I would not do this again.

Operator response

Thank you for taking the time to share your feedback. We're pleased to hear you enjoyed the glass bottom boat tour and the opportunity to see the coral and marine life. We're sorry to hear that Green Island wasn't quite what you were expecting. As a protected coral cay within the Great Barrier Reef Marine Park, it offers a unique combination of rainforest, beaches, and reef experiences, which many guests enjoy. We appreciate your comments and will take them on board as we continue to work with our island partners to provide the best possible experience. Thank you again for your review.
