This is a great trail for snowmobiles in the winter but it is not for biking. Parts of the trail have been used by 4 wheelers, even though this use is prohibited, and they really chew up the surface. The gates at various places do not stop the 4 wheelers. This trail has great potential, but unless the State of NH initiates some serious resurfacing and keeps the 4 wheeler of the trail, it is just going to be another trail to stay away from.
