One of the southernmost trailheads for New Hampshire’s Northern Rail Trail is on Depot Street in Boscawen, just north of Concord. A little informational sign on the stretch of road shared by US 3 and US 4 points to the side street.
The trail surface invites biking, which means it’s fine for walking, too. The ambitious traveler with the right kind of bike could go clear to the other end of the trail in Lebanon in one trip.
I found the Depot Street trailhead on an overcast November afternoon that was warm enough for me to walk without my jacket. In the hour I was there, I covered about three miles. Along the way: a ball field, a farm with its big mown field, a bend in the low-flowing Merrimack River.
