All riders will likely appreciate the flat and even trails over beautiful wet marshlands and a quiet forest trail system, through a couple of tunnels. The trail is mostly hard pack with occasional loose chunk rock, gravel and mud.  The Rockingham system includes two branches: the Fremont branch offers more than 18-miles of rail trail beginning at Depot Road in Windham, NH, and ending just before Route 125 in Epping, NH; and the Portsmouth branch which offers over 28 miles of trail running from Manchester, NH, to Newfields NH.
