3.00The 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.

5.00Fast 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.
