Starting from Mogo campground, Circuit Flat walking track undulates steadily through coastal heath and dry sclerophyll forest, with the distinctive turquoise parrots foraging in the trees overhead.

Turning left at Old Great North Road, the scribbly gums part and you'll arrive at Circuit Flat Bridge, the fourth-oldest bridge in Australia, built in 1831 by convict gangs under the direction of overseer William Barratt. It once linked Sydney to farmlands in Hunter Valley. Though the area fell into disuse, a large amount of the impressive bridge remains, as a reminder of earlier times.
To return to the campground, either retrace your steps or continue north along Old Great North Road to Mogo Creek Road and turn left there. For truly adventurous hikers, Old Great North Road extends 42km between Wisemans Ferry and Mount Manning.
