Had a fantastic outer reef snorkel with Aly. Learnt so much. We had an amazing time. It was a shame other tourists lacked basic manners and respect as that was the most disappointing thing about the trip, especially on the boat.

A fun day on the waters of Green Island. Warm water swimming with the turtles. Snorkel equipment available to hire. Glass bottom boat was interesting & informative. Very busy boat trip with tourists. Worth a look.

Amazing place, the tour staff was excellent and very caring, I highly recommend to stay in the most controlled area near the life guards and also recommend to listen and to follow the instructions suggested by the tour guide. The reef can be deceiving because the current can be very strong at times

A great day out - delicious lunch, I chose the glass bottomed boat and semi-submarine. The boat was good but the semi-sub was excellent - so much better perspective I would highly recommend this element. Be sure to sit on the wharf and watch for turtles coming up for air. A really good day out.

We arrived in Cairns and took a trip to Green Island to do some snorkeling. We booked our snorkeling on the Green Rocket ship/boat. The guide who took us out was named Anzac, he was from New Zealand, a great guy who took us through so many shoals of fish, giant clams and turtles it was unbelievable. We also had a bonus while walking along the pier, two eagle rays leapt out water right in front of us. Definitely worth the trip.

Had a fantastic time with Steve and his offsider when parasailing on the green island. Steve made it fun and made sure we were at ease. He had a very friendly and cheerful personality. Would highly recommend participating in this experience with Steve. Photos were brilliant and nothing was too much trouble. Thank you Steve.

Dont expect 5 star resort. It is very eco friendly. Do expect pristine beach with crystal clear ocean swimming with fish and snorkling. Definitely recommemd a glass bottom boat ride. The reef and what swims below was amazing. Spotted whales on the trip back to cairns. A perfect day.
