Mansfield Hollow State Park

Mansfield Hollow State Park, located in northeastern Connecticut near the towns of Mansfield, Windham, and Chaplin, centers around the Mansfield Hollow Reservoir, an impoundment on the Natchaug River. The park spans over 700 acres of forested land, wetlands, and open water, providing habitat for a variety of wildlife such as deer, beavers, and migratory birds. The area was initially developed in the 1950s as part of a flood control project by the U.S. Army Corps of Engineers, creating Mansfield Hollow Reservoir to control water levels downstream. Today, the park offers visitors numerous recreational activities including hiking on well-maintained trails, mountain biking, non-motorized boating, fishing for bass and trout, picnicking, and seasonal camping. The park's landscapes feature mixed hardwood forests, wetland ecosystems, and the reservoir itself, attracting anglers, paddlers, and bird watchers throughout the year. Key landmarks include several developed picnic areas, a boat launch, and a small campground with both tent and RV sites. Its proximity to major highways from Hartford and Providence makes it a popular getaway for city residents seeking outdoor adventure. Winter months support ice fishing and snowshoeing when conditions allow. Overall, Mansfield Hollow State Park appeals to visitors looking for a peaceful natural setting enriched with water-based recreation and trails suitable for a variety of outdoor skill levels.
