Come fall, the sugar maples in the surrounding mixed hardwood forest add a blaze of brilliant orange to the landscape, making Route 2 a favorite of leaf-peepers between the end of September and Columbus Day weekend. But if sharing the two-lane road with thousands of rubbernecking drivers becomes wearisome, consider taking a road less traveled. Almost any road will do, but a loop along Route 116 through Ashfield and Conway, a few miles south of Route 2, passes over several historic covered bridges and offers enough pastoral beauty to more than compensate for the detours.
