Brady's Run County Park features 20 miles of hiking trails near Beaver Falls, PA.
on Pa. turnpike heading towards Ohio get off at the Beaver Valley exit. Best bet is to turn left off of exit towards Beaver Falls and stop at gas station for directions. If coming of Route 60 from Pittsburgh get off of last exit before toll road (beleive it is Chippewa exit). At stop light at end of ramp take right and continue till a stop light, at the stop light take a right and park either in the dirt parking lot on the right (there is a large map there) or across the street in the ice rink parking lot. Also, go to ClubMTB.com for directions if you cannot understand these or contact Denali Cycles in Bridgewater, Pa for directions and trail maps, weekly rides (great group of guys and girls) with all difficulty levels.
