Eventually, there is a turn off the trail along a track through bush and sandstone rock platforms. This part of the trail is excellent with great views towards Mount Wondabyne.
The track reaches another service road and after a short walk there is a turn off to another track. This track passes close to the summit of Mount Wondabyne. Near the top of the track is a turn off towards the summit. This involves following a track and some rock scrambling. Heaps of fun.
Retracing the summit track then continue along the main track to another service road that passes Old Gosford Quarry and joins onto Woy Woy Road.
