Bartholomew’s Cobble in Sheffield a Trustees Trail, my vote for most interesting full of every aspect of a great trail including the enormous cottonwood trees, the rocky cobble, bridges, fields, vistas. stairs, steps, and the Housatonic River. We even saw two fawn on the tulip tree trail. We hiked all the trails, four hours. A must hike! I took 140 photos it was that good!#hikethehilltowns with the #westernmasshilltownhikers
