At the end of ferguson street is a dirt track. Head down there and there are tracks leading off both sides. Some come to dead ends and some loop back.
If you turn left as you head in, you will go down to a dam. Turn left and follow the track around the dam and it will take you to the old wheel house of the old abernethy colliery.
There are lots of tracks with great rock climbs and decents, a few creek crossings but are dry in summer. Good fun for a few hours and to get to know your limits.
