The road will level out and begin to descend. After passing a log cabin on the right, look for the parking lot on the left at the top of the hill. Except for a short section of two-way trail leading from the parking lot southerly along a forest road, the remainder of the trail is made up of various loop sections totaling 13.6 miles. From the intersection of Routes 190 and 171, adjacent to I-84, proceed easterly 1.3 miles to the entrance of Bigelow Hollow State Park on Route 171. The Nipmunk Forest snowmobile trail begins at the first hiker information sign on the right after entering the park.
Parking is provided for a limited number of vehicles.
Starting in an easterly direction, the snowmobile trail traverses an old woods road and serves two-way traffic for a short distance. The remainder of the run forms a series of loops providing considerable adjustment for time and distance. Total trail mileage is 9.0. Located in evergreen woodland, the trail winds through ledges and is moderately demanding of operator skill especially in narrow passages. Follow the forest entrance road for approximately 1 mile.
