The gateway to Queensland's tropical north, Cairns is a laid-back city best enjoyed outdoors. No trip to Cairns is complete without visiting the Great Barrier Reef, the world's largest coral reef system. Cairns has a thriving café scene, with many trendy cafés dotted along Grafton and Spence streets. The World Heritage-listed Daintree Rainforest is about two hours drive north of Cairns and can be seen on a day trip from the city. Discover some of the reef's unspoiled islands from Cairns.
