Great experience from check in at the marina to getting off the boat staff were amazing and so helpful. Green Island was great beautiful clear water to snorkel in, nice island walk and the glass bottom boat experience was the best one I have had.

Snorkeling equipment is provided completely and is in the process of being preosi. Of course, you can also bring your own equipment. It is advisable to borrow a full body suit (not neoprene) in addition (strong sunlight - risk of sunburn). This is then calculated separately.
Disappointing reef tour

You’re pretty much on your own. You’re dropped off on the island which says it has a resort but actually there is just a small swimming pool, maybe 2 food shacks and a small dive shop where you pick up your snorkeling gear. It was extremely windy so the water was not clear and everyone we talked to that went snorkeling saw nothing so we decided to not do that. Of course the tour company had no control over the weather… we knew that. Considering the weather though, was there some less windy place we could have been taken to be able to see the reef?? Or maybe a longer glass bottom boat tour?? We just didn’t feel that we really got to see the reef which was the whole reason we booked the tour
Great place if you just want to relax

It was not a bad activity, but I wish I would’ve used the one more day I had on something else. I would recommend going on a boat and snorkeling instead of being on this island. The short boat ride to a reef to go snorkeling was worth it, but it was extra. I went to go see the crocodiles to burn up time that was extra….It is a lot of time to spend there with limited activities to do. However, the staff were extremely friendly and outgoing.
