Swim, walk around the island, croc shows! Something for everyone in the family. - It was great!! Handy to have dive shoes so you can neatly walk out far enough to snorkel during low tide (not a problem during high tide).

Worth it - My friends and I were originally booked for another tour and so they rebooked us with this one! This was a pretty good tour! The island is fun to explore and we were able to swim with sea turtles and see lots of colorful fish. The coral itself isn’t that vibrant but it’s still pretty cool. The food and drink accommodations were very good as well.

Relaxed and beautiful day - 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.

Highly recommended - I recently had the pleasure of experiencing the services provided by BiG CAT and I am thoroughly impressed. From start to finish, their team demonstrated professionalism, friendliness, and a genuine commitment to customer satisfaction. The itinerary was well-organized, informative, and tailored to our interests, making the entire trip seamless and enjoyable. The guides were knowledgeable, engaging, and attentive to our needs. Overall, their exceptional service exceeded my expectations, and I highly recommend BIG CAT to anyone looking for a memorable travel experience. I look forward to booking with them again in the future.

I want to go back! - Green Island itself was amazing. We saw turtles by the pier, got to snorkel right off the beach, and there's a log of amenities. I could easily spend days hear, much less the 6 hours we had. It looked quite busy when we arrived, but it didn't feel overcrowded at any point. All of the staff were very friendly and helpful. There is a fee to hire wetsuits/life vests if needed. Also, if you get sea sick, take tablets before the boat ride over. it's 45-55 minutes of the most insane bouncing ever 😭 but it was worth it!

Good tour for the money - 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.

Wonderful day out - 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.

Great Barrier Reef - The lunch location is very crowded. Better announcement about Green island as a place to go after lunch.

Green island snorkeling - This tour group was not the best for first-time snorkelers or non-swimmers. They didn't give any instructions on how to use the equipment or direct to where one could watch an instructional video during the cruise.
