Green Island with Big Cat Cruises. A family run charter, not too big to remember that the customer matters. Big Cat offer full and half day transfers to Green Island with as many or as little options as you want. Always popular with kids.

Flames of the Forest, Savour some traditional ingredients in a 5 star menu, set in a stunning rainforest location.

Tandem Skydive from 14000 feet, While you can do a tandem skydive anywhere in the world, not many places offer a coconut fringed beach landing and those incredible views of the reef. It's fortunate you're strapped to an instructor or you may forget to open the chute.

Bungy Jump with the originals. Australia's first purpose constructed bungee tower set in a beautiful jungle setting.

Do a dive with Silverswift. This brand new purpose built dive boat is the ultimate dive platform to explore the underwater wonderland. With impressive customer to staff ratio's you will be satisfied with your decision.

Spend a day at the Boulders with a picnic lunch and a few cold beers. Some organised tours will go there but why not rent a car and explore.
