Between Great Barrington and the Connecticut state line, US-7 winds through Sheffield and is lined by dozens of antiques stores, earning this stretch the nickname “Antique Alley.” Sheffield also has a faded gray covered bridge, just over 100 yards east of US-7 on the north side of town. At the south edge of Sheffield, just west of US-7 off Weatogue Road, the natural rock garden of Bartholomew’s Cobble ($5) rises up above the west bank of the Housatonic River. Geology and weather have conspired to produce an outstanding diversity of plants and birds—800 species, including beautiful wildflowers—within a relatively small pocket of fern-covered limestone outcrops and broad meadows. At the center of the 329-acre state-run reserve, a pleasant walk up Hulburt’s Hill gives a broad view over the surrounding Berkshire scene.
