West Suffield Mountain

West Suffield Mountain, est. 710 feet , is a traprock mountain ridge located between the Berkshires and the Connecticut River Valley in north-central Connecticut. It is part of the narrow, linear Metacomet Ridge that extends from Long Island Sound near New Haven, Connecticut, north through the Connecticut River Valley of Massachusetts to the Vermont border. West Suffield Mountain is known for its scenic ledges and woodlands, unique microclimate ecosystems, and rare plant communities. It is traversed by the 51-mile Metacomet Trail, and the 110-mile Metacomet-Monadnock Trail begins at the northern foot of West Suffield Mountain.
The West Suffield Mountain ridgeline rises steeply between 250 and 550 feet above the Connecticut River Valley to the east, with a high point of 710 feet above sea level. A prominent landscape feature, it is roughly 4 miles long by 1 mile wide at its widest point, although the steepness of the terrain makes the actual square mileage much larger.
