"Since bicycles are prohibited from all sections of the Black River County Park trail system, I decided to experience this trail by walking the one-mile trail segment from historic Cooper Mill to Chubb Park (both located on Route 513 in Chester).
Cooper Mill’s Visitors Center is equipped with excellent public parking, restroom facilities, and many historical interpretation markers. The trail to Chubb Park begins here at a tunnel that safely carries pedestrians under busy Route 513, and heads northeast towards US Route 206.
Trail surface conditions were very rocky and uneven in some spots, but in others quite typical of what you’d expect to find on a rail trail (flat and obstacle-free). The scenery along this short stretch was very pleasing; views of the Black River, some heavily wooded areas, the backs of expensive homes, and a well maintained recreational field complex.
The majority of Black River County Park lies south of Route 513. The former railroad right-of-way incorporated into the trail system here is located adjacent to Cooper Mill and heads south for about one mile. I walked for a few hundred feet on this stretch and noted that the surface was flat and dry, but unfortunately lined with many tree roots and rocks.
I would highly recommend this trail to sure-footed hikers/walkers seeking a location that offers a history lesson as well as a nice place to get some exercise."
