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.

As a decent this was awesome! Right at the bottom of the first downhill you have some loose sand so be cautious. Right after that is a beautiful pond you loop right around, then another excellent downhill.

Very smooth gravel. Could even get out of saddle for some sections of the climb without losing traction

There are not many trails at Clarence Fahnestock Memorial State Park that are open for mountain biking. Luckily this one is one of them. Expect great flow and some hike-a-bike sections.
