The park land was gifted to the State of Connecticut by Clarence C. Wadsworth in 1942.
The waterfall is formed by the Coginchaug River cascading over a trap rock ledge.
Little Falls, a smaller cascade within the park, was previously powered by a small dam for a long-defunct mill.
The park contains remnants of an old stone wall system from its time as a private estate.
Certain trails within the park connect to the larger regional trail systems in Middlesex County.
Wadsworth Falls State Park is centered around a picturesque 30-foot waterfall fed by the Coginchaug River. The 285-acre property was originally the private estate of Clarence C. Wadsworth. The park features a diverse trail system spanning over 15 miles, traversing hardwood forests and sandstone ledges. Visitors can observe two distinct waterfalls: the primary Wadsworth Falls and the smaller Little Falls located in the western section of the park. Swimming is strictly prohibited at both waterfall sites due to water quality and safety concerns. The park serves as a protected habitat for diverse bird species and native Connecticut flora. An extensive network of gravel and dirt paths provides accessibility for hikers, cyclists, and cross-country skiers. The site is managed by the Connecticut Department of Energy and Environmental Protection.
The viewing platform at the main Wadsworth Falls offers the most stable and unobstructed vantage point.
Wear waterproof footwear as paths near the Coginchaug River are often muddy.
Bring insect repellent during the summer months, as the forested areas are prone to mosquitoes and ticks.
Download an offline map, as cellular reception can be inconsistent within the deeper wooded sections of the park.
Do not attempt to swim or wade in the waterfall basin; parking at the main lot during peak holiday weekends often reaches capacity early.
Open daily from sunrise to sunset year-round; limited parking access during extreme winter weather conditions.
Stay on marked trails to prevent erosion and protect native plant life; dogs must be kept on a leash at all times.
