Tri-Mountain State Park

Tri-Mountain State Park is a 157-acre nature preserve spread across Wallingford and Durham, offering hiking trails through forested hills and open woodland areas. The park incorporates sections of Fowler Mountain and Trimountain, creating varied terrain for visitors to explore.

The park was established in 1925 following John B. Kendrick's purchase of land on Trimountain's southern peak in 1906 and his subsequent donation of six acres to create a public space. This initial gift formed the foundation for the protected area that exists today.

The Connecticut Department of Energy and Environmental Protection manages this public recreation area, maintaining its role in outdoor education and conservation.

Access to the park is available only through the Mattabesett Trail, with no direct road entry to the grounds. Visitors should wear proper hiking footwear and be prepared for trail navigation.

The park straddles two counties, Middlesex and New Haven, making it an example of land management that crosses administrative boundaries. This border-spanning location shapes how the park functions today.
