The trail is open all four seasons for multiple uses and I imagine it’s gorgeous in the fall with the colors. The rail line ran from White River Junction, Vt., to Concord from the 1840s to the 1960s. At the northern end of the 10-mile section we did, there’s an old train depot, Potter’s Place, which in itself, is pretty cool.
Directions and Parking: There are 3 parking areas along this 10-mile section. We parked at the Highland Lake Inn, which is on the SE side of the trail and serves as a welcome center for the trail (has toilet facilities). There is also parking at Blackwater Park and Potter Place. Those areas actually seemed more crowded than where we parked. All of the parking areas are off Route 11 in Andover. Check out http://www.fnrt.org/ for maps and more information.
What You Need to Know: The bike path is wide in most sections, but it’s used for multiple purposes, so be conscious of bikers, walkers, runners, strollers and horses and yield-to/passing rules. The path is not paved, but the crushed stone was still smooth enough. It was not too crowded when we went on a Saturday, but I imagine it does get crowded. When you park at Highland Lake Inn, you are not at the SE terminus of the trail. It goes another 2 miles or so over the Franklin town line. Potter Place is the NW terminus of the trail.
