New Norfolk Bridge to Bruny Island (Dennes Point) 58km

Geologically, Bruny Island actually consists of two land masses—North Bruny and South Bruny—that are joined by a long, narrow, sandy isthmus, often referred to as "The Neck". The island has a total length of approximately 50 kilometres (30 miles). The holiday village of Dennes Point is located in North Bruny, while South Bruny is the site of the towns of AlonnahAdventure Bay, and Lunawanna.

Outside its settlements, the island is covered with grazing fields and large tracts of dry eucalyptus forest. Inland forests have been logged, but other large sections—mostly along the southeastern coast—are preserved as the South Bruny National Park. While the seaward side of the island features two long beaches—Adventure Bay and Cloudy Bay—it is for the most part extremely rugged, with cliffs of dolerite over 200 metres (660 ft) AHD in altitude. Bruny's channel side is more sheltered and a favourite fishing and recreational boating area for local and interstate visitors. Adventure Bay is located on the eastern side of the isthmus, while Isthmus Bay is located on the western
