School Mountain Road Trail is an old farming road which has been taken back by nature. The forest has grown around it, so that it is now a green, shady hiking trail. You can still see remnants of the life that used to be along the old road, including an old abandoned farm house.

An exhilarating descent, an exhausting climb, or both—with plenty of views along the way. Hard packed gravel through and through with minimal car traffic. Plenty of parking at the Bird and Bottle Inn.
