Beacon Hill, (est.) above sea level, is a traprock outcrop located southeast of New Haven, Connecticut overlooking the mouth of the Farm River 1.2 miles north of Long Island Sound. It is the southern-most notable summit of the Metacomet Ridge which extends from Long Island Sound near New Haven, Connecticut, north through the Connecticut River Valley of Massachusetts to nearly the Vermont border. Beacon Hill is known for its scenic ledges overlooking a surrounding salt marsh and the greater Sound and for its unique microclimate ecosystems and rare plant communities. Beacon Hill is traversed by several trails, most notably the Branford Trail. The Shoreline Trolley Museum runs trolley service to the base of the hill.
