Freycinet National Park starts at Coles Bay and stretches southwards on a long peninsula dividing the Tasman Sea from Great Oyster Bay. It is home to the famous Wineglass Bay. Overnight accommodation is also available at Coles Bay, Bicheno and Swansea.
Driving time from Port Arthur to Freycinet is about 3 hours, though there is plenty to stop and see along the way. You can easily spend 5 or more hours on the trip.
