Northern Rail Trail: The industrial Merrimack River region is oft overlooked when it comes to fall foliage, but the Northern Rail Trail, which runs from Lebanon to Boscawen, is a fantastic, scenic run. At 58 miles, the NRT is the longest rail trail in New Hampshire, so you may want to choose just one section for an out and back. The trail runs through the towns of Danbury, Wilmot, Andover, Franklin, and Boscawen, so you have options upon options. Just beware that not all sections have been primed for running — some are still covered with ballast formerly used to hold railroad ties in place. Two good starting options are the Country Store in Danbury and the Highland Lake Inn in Boscawen, which serve as welcome centers to the trail and are complete with amenities. As far as scenery goes, the section along the Mascoma River between Lebanon and Enfield winds through a lovely glacial valley before meeting up with the shores of secluded Lake Mascoma. The views of the Merrimack River on the Boscawen end of the trail are also remarkable, and easy to access. To determine which rivers, lakes, and trestle bridges to include in your foliage view, check out the maps from the Friends of the Northern Rail Trail.
