The Tasman Peninsula is best known as the home of the Port Arthur Historic Site, where the tale of convictism is interpreted in a way that transports visitors to another time and place in history. The site is one of Tasmania's major attractions. But the peninsula has a lot more to offer.   The drive from Hobart offers glimpses of an exciting coastline, surging ocean and early morning mist on the water, while passing through sleepy fishing villages. The road winds down to Eaglehawk Neck. It's a dramatic view across Pirate's Bay to the neck, where ferocious dogs were once used to prevent escaped convicts from escaping.   Here you'll find unusual rock formations like Tessellated Pavement - just one in a number of incredible geographical attractions that include Tasman Arch, Devils Kitchen and the Blowhole.   The rugged sea and coastline has resulted in many shipwrecks, making it popular with divers. The temperate waters are clear and feature some of the largest kelp forests in Australia. The bays are rich in marine life making it enticing for anglers as well.
