The developing area of East Hereford (SE of Coaticook) for mountain biking has 2009 version of trail maps at this link.
Remember that this is a fairly isolated area, and don't go out without a bit of a plan B emergency kit like a first aid kit and a rain jacket and maybe a mini survival kit. Or, maybe we worry too much.
Anyway, check out this destination, we like it for road riding too.
