Surf: Dirk Hartog Island is one of Australia's most unique and remote eco-tourism destinations, but it has limited accommodation and access is through Denham via car ferry (4WD only) or light plane to this World Heritage Site. At the northern tip is Turtle Bay, where a long workable left is on offer, protected from S winds. Rips beside the coralline reef can be vicious and remember this is the entrance of the aptly named Shark Bay. Directions: Dirk Hartog Island northern tip Environment: Hardcore surfers only. Boat/flight from Denham.
