Just a 20-minute ferry ride from Airlie Beach, cosmopolitan, family-friendly Hamilton Island is full of surprises. Although best known as a resort island, only a third of the island is in fact developed, with the rest left in its natural bushland state. Wander past ancient cycads and gum trees, or head to the water’s edge to glimpse turtles and humpback whales. If you manage to tear your eyes from the heavenly views, there are copious activities to fill your time. Snorkel, play world-class golf or go sailing—or simply get a spa treatment and sip a cocktail as you watch the sun set over the ocean.
