Fantastic day on the island. All at your own pace. Explore the crocs, it’s worth it then hopefully swim with a turtle. I did.

Time on the boat was very short. Excluding loading and unloading, we spent just over 20 minutes looking at/for fish and turtles. Captain was knowledgeable and helpful. We did see quite a few fish. There is too much light coming from the sides of the boat reflecting off the glass floor to be able to take good photos.

The island was so beautiful and to be able to see the reef was an exciting experience. Unfortunately it isn’t very long, it is over too quickly. However our captain was very knowledgeable and entertaining.

Most of the reviews i write are positive because when i pick one tour i have done the research to match my preferences. This experience was not good. Green island is overhyped, and unless you do scuba diving, not much to do, as the beach is not that good either. Facilities are dirty, no good food. We took the glass bottom boat tour; it’s too short, the fish we got to see are “artificially” attracted by the boat operator feeding them, and the corals are underwhelming. On the positive side the staff of the catamaran are very good, helpful, cheery and with a contagious enthusiasm.
