What sort of trails? If you want trailcentre and a skills area you're pretty close to Gisburn, probably the same travelling time to Llandegla, both worth the drive for a day out . Smaller, fun little trails on your doorstep at Philips Park (Prestwych). and Clayton Vale, or of course you're within striking distance of loads of bridleways, north into the Dales, South into the Peaks, or East into the South Pennines.
Google can be a good source of information, and either a subscription to the
Ordnance Survey map services, or a paper copy and a sense of adventure.
Folk upload their routes to Strava, Mapmyride, bike-hike, mapometer and other mapping sites, so have a search on some of them..
As the title says. Does any one know of any MTB trials near Bury
