Clarence Fahnestock Memorial State Park is a delight for outdoor enthusiasts. This 14,086-acre park, covering land in Putnam and Dutchess counties, boasts hiking trails, picnic areas, scenic campground, and abundant opportunities for boating, hunting, fishing, and birding. The park is also home to the Taconic Outdoor Education Center, which provides high-quality environmental programming and Fahnestock Winter Park, which includes 20 kilometers of groomed trails for cross-country skiing and snowshoeing.

Fishing by boat is permitted at Stillwater and Canopus Lakes. Fishing at both lakes and four ponds is excellent in all seasons for anglers seeking bass, pickerel, perch or brook and rainbow trout. Please note that all freshwater fishing requires a permit from the New York State Department of Environmental Conservation. This permit can be obtained from town halls and many sporting goods stores.

The scenic campground, formed along the park's natural rock ridges, provides alcoves of privacy and tranquility for campers. Each of the 80 campsites has a picnic table, charcoal grill, and fire ring. Additionally, there is an area for RV camping. Although there are no hookups available or dump station, restroom and shower facilities are centrally located to all RV and tent sites. The campground's nature center houses environmental displays and a variety of touch boxes.
