Brief description: Johnsonville Park is part of one of the largest areas of continuous native vegetation in the city, which is recognised as a key native ecosystem.
The Northern Walkway climbs steeply from Truscott Avenue up to Mount Kaukau and continues on to the Botanic Garden.
The Skyline Walkway begins at the saddle of Old Coach Road and follows the ridge to Mount Kaukau.
Parking: Large car park at Truscott Avenue entrance.
Accessibility: Steep in places.
Dogs: Dogs must be kept on a leash.
Mountain biking: The Old Coach Road trail is a good climb up the wide heritage-listed track from Ohariu Valley to the ridgetop. There is also the Skyline Walkway that follows the ridgetop south from here above the western suburbs.
History: A tunnel hewn out of solid rock can be found near the top of the Truscott Avenue track. This dates from around 1910 and was the outlet for the old Onslow County Borough water reservoir on the other side of the ridge.
At the top of the track the reservoir dam and pump can be seen. Water was pumped up from a dam in Ohariu Valley to the reservoir before flowing under high pressure to Johnsonville.
