Bring a towel, check out the crocodile feeding at 1:30, there is a limited selection of food for sale on the island but they have showers and restrooms and a path thru the island that’s paved. The boat ride is bumpy so consider Dramamine. Loved the snorkeling but the coral by the island is pretty dead although the fish are beautiful and abundant. Don’t see a sea turtle but others did. The walk around the island took about 30 minutes. Nice safe beach for kids with a lifeguard. If you pay more you can get a guided tour away from the island where it’s probably more pristine. Felt we got our moneys worth.

We had a lovely day on Green Island. The boat ride over was a bit choppy and my daughter became sea sick but the lovely crew went out of their way to help her by taking her outside for fresh air and giving her ice cubes.

The Big Cat tour is smooth and pretty organized. The marine biologist explained and shared about the reef and reef creatures well and we saw the cute sea turtles and other fishes like Trevally readily. It is a relaxed and beautiful time in Green Island, no wonder it is a popular spot for tourists and locals.

Great and professional service. Friendly staff. Green island is amazing. Well worth it. This is a ‘self guided’ product, but with plenty of options to personalize and get more assistance to enjoy the reef.

We really enjoyed our trip to Green Island. We loved the glass bottom boat and semi-submersible trip around the reef. The staff was engaging and pleasant.
