There are two Pine Mountain trailheads, the North one on the end of Promenade Street in Gorham and the south one on the Pinkham B/Dolley Copp road. Pinkham B road is a state road and is not gated but is also not plowed. The hike in from Gorham is longer but goes through some nice woods. Just be careful, where it crosses the Pipeline clearing its crosses it at a diagonal. To get to the trailhead in Gorham keep walking on what looks to be driveway with the cemetery to your right. Go past a gate and the trailhead is in a gravel pit.
