More ways to explore the area's outdoor wonders
Morning light strips across the turquoise shallows of Carnac Island as a catamaran slips away from Fremantle, sails filling with the clean Western Australian breeze. Australian sea lions sun themselves on rock ledges and watch the boat with bright curiosity, while the western cliffs drop into a sheltered anchorage that invites snorkelers and kayakers into clear, shallow water.
