Fort Denison

First inhabited in 1788 by a biscuit stealer, Fort Denison was an isolated prison for Sydney's most dangerous convicts. Also known as "Pinchgut" due to the meager rations given to its prisoners, the island has a grim history of incarceration. These days, the island is a part of Sydney Harbour National Park and visitors are offered a cannon museum, a bell tower, a working tide gauge, a beautiful view and cafeteria. Bookings essential.
