The Tasman Peninsula is well known for its rocky eastern coastline. Much of it is now in the Tasman National Park. At Eaglehawk Neck the rocks have made many strange shapes and patterns. These include Remarkable Caves, Tasman's Arch and the Tessellated Pavement. On the south of the peninsula are the highest sea cliffs in the southern hemisphere, rising 300 m above the Tasman Sea at Cape Hauy. The peninsula is claimed as one of Australias best surfing spots at Cape Roaul and Roaring Beach.
