Green Island day visit

4.00Beautiful island, if you don’t snorkel though there not much to do. Glass bottom boat is good. Food sold on the island is basic. Not all menu”s are written in other languages with pictures. Overall relaxing day.

4.00Ferry to island 50 minutes then choice of snorkeling vs glass bottom boat. Added cost if you wanted both. Good facilities on island. Problem is that it was not the deeper reef area which was another 45 minutes further out with much greater diversity of species and much larger fish. Several friends took that trip and I now wish we had. Didn’t feel like the real Great Barrier Reef. More money but the real deal. Glass bottom boat 30 minutes duration then several hours remaining to walk or swim or eat.
Great option

5.00The island looks pretty. However, if you want to snorkel and observe the Reef fauna of Green Island you need to swim quite far from the shore. But it’s worth it - you might see turtles and harmless reef sharks of small sizes (1 meter or less). I highly recommend this trip.

3.00Quite honestly, it was a waste of money. All we experienced was 45 minutes of snorkeling. Despite us informing the staff upon booking that one individual couldn't swim, additional assistance wasn't provided. You have to be able to swim to enjoy this activity, so a waste of money and time.
