The woods are about the size of a postage stamp, so there's not really going to be too much, but there are a few lines that people ride… most of which are reasonably obvious, and most seem to start from the very top of the hill.
Also, I'm not sure exactly how sanctioned the riding there is, unlike the stuff over the back of Hemlock, which is… and as you say, it's usually full of people, kids and dogs so hooning about on the bike is never gonna be the best option! Although at night it's pretty much deserted… :o)
You'd probably be better getting yourself over to Bestwood though really…
