Although there are no views from the Tunks Trig Station, it makes for a pleasant bushwalk along the Mitchell Firetrail in Dural. Only the last few metres requires some bush-bashing to reach the abandoned trig station, which is about 30m from the fire trail. The trig has an intact concrete pedestal, but no mast or vanes.
The nameplate has alse been removed from the concrete base.
Getting to Tunks Trig via the Mitchell Firetrail
A gravel service trail heads south-east from a locked gate at the end of Mitchell Road in Dural. (The first 0.6km is through Crown Land, so dogs are allowed.)
After about 500m, you see a tall telecommunications tower which rises well above the trees – the Tunks Trig is in the bush on the right, just before you pass the tower (you can’t see it from the firetrail).
Soon after you pass the telecoms tower, you enter Berowra Valley National Park (no dogs beyond this point, and although it’s a firetrail mountain bikes are also not permitted).
The Mitchell Fire Trail continues another 1.8km, and is either flat or descends gently, with the very last bit descending quite steeply. There’s a nice view at the end of the firetrail over Berowra Valley National Park, with a few rock platforms to sit on if you want to enjoy the view before the walk back.
The walk to the end of the fire trail is about 4.8km return; if you just want to visit the trig station it’s about 1km return.
