Located at the access to Tasman National Park, and sections of Cape Raoul and Shipstern Bluff. A great base from which to discover popular hiking, climbing, and world-renowned surfing in the area. There are Mountain biking options in the area but just not within the National Park. Campers must be nature-orientated travelers, this is not a place suitable for Port Arthur only tourists.
