The glass bottom boat was a waste of time as it was only 1/2 hour long and only went a few metres from the shore. Only fish seen were fish that were being fed to be at a certain location. Not a very good experience.

Fast cat to Green Island and snorkelling, half day. Entire process was conducted by staff who were cheerful and inclusive. Once at Green Island, our expectations were met by what had been explained (were able to go straight to the facility of our choice), exceeded expectations by the lush greenery and cobbled path to the beaches. Once in the water we were taken into another world where we could join all the other life under the sea - absolutely wonderful!!! At the end of the day however I had forgotten to take into consideration the sun could burn through the water and suffered sunburnt legs.

Snorkeling was amazing. Great opportunities to see a range of fish and easy and accessible for children. We had a brilliant day out

The glass bottom boat viewing the coral and exotic sea life in the deep waters was a wonderful experience for us who did not want to snorkel in the shallow water off the island. A must do for any visitor to Green Island

The whole experience was great. You take the boat out and choose your extra expedition on board. I chose the glass boat and was able to see the reef so well. We even spotted a turtle and a stingray. The island itself has a little rainforest walk, food huts, bar, and of course, the beach. There was a pool included with this booking that they share with the hotel, but it looked pretty dirty. Plenty of washrooms and change rooms. Nice and relaxing day.
