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.

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.

A great ride to a great experience

Note that you have to go to the tour office to get the actual tickets ahead of the boat time. The boat was fast and comfortable. The staff was very friendly. Green island was great and had super snorkeling. There are restaurants and food options available. They had public shower area to rinse off. Bathrooms on island.

Very short experience.

I chose to go on the flat bottom boat. It lasted only half an hour and the rest of the time I spent walking on the forest boardwalk. I think the tour is better value for those who snorkel.

Operator response

Thank you for taking the time to share your feedback. We’re sorry to hear you felt the experience offered limited value. The glass bottom boat tour is designed as a guided reef viewing experience, typically around 30 minutes, allowing guests to view key coral and marine highlights with commentary from the crew. Many guests choose to combine this with snorkelling or time on the island’s rainforest boardwalk to make the most of their visit. We do appreciate that guests have different expectations and preferences depending on how they choose to spend their time on Green Island. For those who snorkel, there is certainly more time spent in the water; however, the glass bottom boat and island walks are designed to provide a more relaxed, above-water way to experience the reef environment. Thank you again for your feedback—it is appreciated and will be shared with our team as we continue to review how we present our inclusions and guest experience.
