Beside the winding Housatonic River, in Sheffield, Massachusetts, rises Bartholomew's Cobble, a natural rock garden of ferns and rare wildflowers. Visitors may explore this delicate woodland community by walking Ledges Interpretive Trail. A network of other trails leads through forest, meadow and pastureland to the top of Hulburt's Hill with its magnificent views of the Housatonic valley. A flyway for more than 200 bird species, this 294-acre Reservation is an ideal spot to study nature, picnic and enjoy scenic views.
