About Clarence Fahnestock State Park

Clarence Fahnestock State Park is a large New York State park covering over 14,000 acres of wooded hills, lakes and trails in the Hudson Highlands region. The park is managed for a mix of day-use recreation and year-round outdoor activities.

Key on-site features include multiple lakes and reservoirs, such as Canopus Lake, and a broad network of trails used for hiking, mountain biking, and cross-country skiing. Campgrounds, picnic areas, and dispersed recreational facilities make the park a regional destination for outdoor activities.

The land was acquired and consolidated for public recreation in the early 20th century and is named after Clarence Fahnestock; over time it has been developed with trail networks and recreational facilities while retaining large tracts of forest and water.

The park lies in northern Westchester and southern Putnam County in southeastern New York State, on the Hudson Highlands landscape north of the New York metropolitan area.
