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).

The Mattabesett Trail is a 62-mile (100 km) long, hook-shaped blue-blazed hiking trail in central Connecticut and a part of the New England National Scenic Trail. One half of the trail follows the high traprock ridges of the Metacomet Ridge, from Totoket Mountain in Guilford, Connecticut, to Lamentation Mountain in Meriden, Connecticut, from south to north. This ridge is known for its biodiversity, miles of scenic cliffs, and rugged hiking. The second half of the trail extends north from Guilford to Middletown, Connecticut, and ends at the Connecticut River. Here, the trail follows an upland of metamorphic rock with occasional views and dense forests. Important features along the trail include Lamentation Mountain, Chauncey Peak, Higby Mountain, Besek Mountain, Fowler Mountain, Trimountain, Pistapaug Mountain, Totoket Mountain, the Broomstick Ledges, Seven Falls, and Coginchaug Cave. The Metacomet Trail continues north from Lamentation Mountain where the Mattabesett Trail leaves off. The geology, ecology, and landscape of the trail are similar to that of the Metacomet-Monadnock Trail to the north in Massachusetts. In 2000, the United States Congress authorized the National Park Service to research a new National Scenic Trail now called the New England National Scenic Trail in southern New England, which includes the Mattabesett Trail as well as the Metacomet-Monadnock Trail and the Metacomet Trail. On March 30, 2009 President Barack Obama signed the Omnibus Public Land Management Act of 2009 establishing the New England National Scenic Trail (and two other national scenic trails).The combination of the Metacomet, Monadnock and Mattabesett trails is also often referred to as the 3-M, MMM or Metacomet-Monadnock-Mattabesett trail. The New England National Scenic Trail will eventually include all or almost all of the MMM trails as well as a proposed extension trail from the southernmost point on the Mattabesett Trail through Guilford, Connecticut to the northern shore of Long Island Sound.

Located on Ledge Hill Road, the district includes two churches (along with their appended halls and parsonages), a cemetery, and Ledge Hill Road itself, which dates to the early 18th century. The arrangement is reflective of a spirit of religious tolerance that manifested in the early 19th century, allowing churches from two different congregations (Congregationalist and Episcopalian) to heal long-standing divisions. The district was listed on the National Register of Historic Places in 1987.
