As its name suggests, Eaglehawk Neck (28 km south) is a narrow bar between Pirate's Bay to the east and Norfolk Bay to the west. This isthmus joins the Forestier Peninsula and Tasman Peninsula and the former Port Arthur Penal Settlement on which it stands in a narrow strip of land which is less than 100 metres wide. It was here, during the convict penal settlement days, that savage attack dogs were chained from one side of the neck to other within reach of each other to deter prisoners from attempting an escape by land. As a sombre reminder of the location's use, a bronze dog sculpture marks the spot where chained attack dogs were once stationed.
Not far from Eaglehawk Neck is Doo Town, where the residents have become very creative - and funny - by incorporating the word "Doo" into the novel names of their properties. Doo Town is on Pirate's Bay, from which cruises up and down the Tasman Peninsula coastline depart.
