About 90% of this trail shares dirt with the Pachaug motorcycle enduro route. There's lots of jeep road, but the kind of jeep road that requires an off-road jeep, not your neighbor's drive to the grocery store jeep. In the fall, loose rocks ranging from the size of golf balls to softballs will hide under massive piles of oak leaves where they wait to take you down. On the few sections of single track, the rocks are embedded firmly in the ground, but along with the roots, this terrain isn't much easier. Spring might seem like a better time to enjoy this route.

Running around Schliersee, about 9km and 300m vertical gain. 

Nice trail from Schliersee to Fischhausen. Back on the west side of Schliersee on road / dirt road and trail.

The Ware River Rail Trail is an unpaved rail bed between Barre and Baldwinville. This route consists of the section from Barre to Rt. 2 in Templeton, which is about 12.8 miles long. There is no direct connection to the Baldwinville section north of Rt. 2. There is a parking area off Rt. 122 in Barre. The route begins at the yellow gate and ends about 3/4 mile north of Rt. 2A in Templeton, where the improved portion of the railbed stops and the snowmobile route makes a sharp left, at the sign saying "Stay on Trail". The terrain is mostly packed dirt and sand, with a few sections of gravel.
