Herrington Manor State Park is a public recreation area on in Garrett County, Maryland. The focal point of the state park is 53acres Herrington Lake. The park lies adjacent to Swallow Falls State Park, approximately 4miles north of Oakland. Both parks are managed by the Maryland Department of Natural Resources.
The park is named for the manor house built by real estate investor Abijah Herrington in the mid-1800s. The property was purchased by the state in 1935 as part of state forest development. The Civilian Conservation Corps subsequently dammed Herrington Creek to create the park's 53acres lake. In 1964, the manor house was demolished and Herrington Manor State Park was established.
The park offers swimming, fishing, boating, twelve miles of hiking and biking trails, and rental cabins.
