Things To Do



157 acres of beautiful forest in Durham and Wallingford, Connecticut make up Tri-Mountain State Park. Hiking is plentiful, and there is no fee to get into the park. The Mattabesett Trail, which stretches 50 miles from Lamentation Mountain to Totoket Mountain, traverses the park for some beautiful vistas. Named for the triangle-like shape, three pinnacles and the three notches between them, Trimountain rises 500 feet.

Access to the Park is via the Mattabesett Trail. The nearest crossing north of the Park is on Durham Road (Route 68) at Reed Gap (at the junction of Rt. 68 and Rt. 157), just a few miles from the center of Durham. On the south, the trail crosses Howd Road west of the intersection with Trimountain Road. There is no road access to the Park.
