Norton Summit is a town in the Adelaide Hills, South Australia, located approximately 12km east of the city of Adelaide. The town is named after Robert Norton, who arrived in South Australia shortly after its proclamation, and made the first recorded climb in the area in 18361.
The area has strong ties to the Playford family. Thomas Playford I settled in the area in 1840s, and many of his descendants were brought up here, including Thomas Playford IV, South Australia's longest serving premier.
