wilderswood BW downhill is one of the best IMO (good for climbing too), others prefer winterhill down to belmont road which is fast but a bit straight for my liking. Theres the cheeky route from telephone masts on winterhill down to the old cobbled belmont road which will then take you to – The ice cream run, its a rock fest but good fun if your into that, make a sharp right when you get to the pigeon tower (or from the pike go down to and passed the pigeon tower, it descends to the top car park.) You can do routes over to lead mines clough, great hill, healey nabb darwen turton etc without much roadwork.
