The 140-sq-km Dharug National Park , also on the north side of the river, is a wilderness noted for Aboriginal rock carvings dating back nearly 10,000 years. You can also check out the dilapidated convict-built Old Great North Rd along the park’s western boundary. There’s drive-in camping at Mill Creek (per night adult/child $10/5), 8km east of Wisemans Ferry, and free sites at Ten Mile Hollow (walk-in only).
