The largest of the paradisaical group to which it gives its name, Whitsunday Island is ruggedly forested, and surrounded by clear teal waters and coral gardens. Its most visited site is the dazzling 7km-long Whitehaven Beach – one of Australia's finest – visited by pretty much every sailing/snorkelling tour from Airlie Beach but still managing to seem uncrowded. The more intrepid will also enjoy the Hill Inlet lookout (for epic lagoon views) at the north end of Whitehaven Beach.
There are six basic camp sites on the island, some with more shade than others. It's hard to beat the Whitehaven Beach camp site for its five-star location. Book camp sites online with Queensland Parks & Wildlife, and see Scamper for camping transfers ($105 to $155 return per person).
