We ride up there most weeks as we are based at the bottom of the fell in Longridge. Plenty of different bits of trail up there but rhe best of it is cheeky footpaths. Possible to put together a good loop of about 20km messing about on the different sections and fireroads. Bridleway to and from Hurst Green is good, think plenty of people ride up from Hurst Green, ride about for a bit then back down.
As mentioned above a lot of the footpaths sections are getting VERY boggy by this time of year! We try to limit how much we ride it now just to prevent it getting totally wrecked!
