I am never sure where to put a "track update" so if this is the wrong spot, someone please point me to the right spot.
Walked into Hidden Valley and up Mount Sturgiss from Sassafras. The road into the parking area is a bit lumpy, bumpy but passable in 2WD car. Did not go out to Folly Point but met a woman who had been out there for three nights and she had done some clearing of the trail but reported that it was hard to follow in spots.
The track to Hidden Valley and Styles Creek definitely has it's moments. Up to Quilty's turnoff and down the valley along Kilpatrick Creek is pretty reasonable - lots of toppled trees, regrowth but no real drama. Where the track climbs out of Kilpatrick Creek and traverses flat ground to the Hidden Valley turn at around 700 metres the track is really overgrown with acacia. If you are lucky you will manage to stay on it, but we lost it multiple times and the bushwacking to "refind" the track is pretty slow going - dense acacia with thorny vines throughout.
The camp at Hidden Valley turn and the few little campsites before that are quite overgrown with acacia but we did have a good camp about 100 metres from the Hidden Valley turn with water from a creek nearby. Finding the tree marking Hidden Valley took some time and we almost immediately lost the track heading towards Hidden Valley. We picked it up again near the cliff line where it contours north. No real sign of any track in Hidden Valley but walking along the west side was fine. Dark Brothers cave seems to be marked wrong on the topo map. If the big cave with obvious camping is Dark Brothers cave it is about 300 to 400 metres north of where it is marked on the topo map.
The chain scrambling up Sturgiss is a bit rusty and held in by a couple of rusty carrots, but seemed OK. Fantastic views from Sturgiss.
