The road to Dampier trig is in really good shape having been freshly graded and Currambene Creek is low so easy to drive up in a regular vehicle.
The regrowth is next level. Much worse, although how that is possible I don't know, than last time we were in the area. Expect to average a kilometre an hour if you are doing well. Some sections are truly hideous, some not too bad.
The Tarlington track has disappeared, at least where it travels up the ridge. I can't imagine what the valley looks like!
We did find vestiges - enough to improve travel - of the old fire road that descended from Dampier Trig. I am happy to send a GPX track if anyone wants it as it will make your life much easier for the first 3 or so kilometres.
