North Fork Mountain Trail features 24 miles of hiking trails near Petersburg Or Franklin, Wv, WV.
a few possibilities on starting points.. most people run a shuttle since it is a ridge trail running 24 miles! There are a few trails spurring off it on the northern half, like Redman Run, Landis trail and forest rd 79 (north half is the all single track half) Those can be used to make a loop if you like to do alot of climbing. If you despise climbing, consider doing with a shuttle because you rack up a fair amount of climbing on the ridge trail alone.
