Totoket Mountain, with a high point of (est.) 720 ft (220 m) above sea level, is a traprock massif with several distinct summits, located 7 mi (11 km) northeast of New Haven, Connecticut. It is part of the Metacomet Ridge that extends from the Long Island Sound near New Haven, north through the Connecticut River Valley of Massachusetts to the Vermont border. Totoket Mountain is known for its 500 ft-high (150 m) scenic cliffs, microclimate ecosystems, rare plant communities, and for Lake Gaillard, a 2.5 mi-wide (4.0 km) public reservoir nearly enclosed by the mountain. The north ridge of Totoket Mountain is traversed by the 50 mi (80 km) Mattabesett Trail and a significant network of shorter trails. The name "Totoket Mountain" applies to both the entire mountain and to a subordinate northwestern peak (577 ft or 176 m).
