Welcome!​

 

The park, comprised of 6,300 acres, extends along 14 scenic miles of Seneca Creek, as it winds its way to the Potomac River. The Clopper Day-Use Area contains many scenic areas, including the 90-acre Clopper Lake, surrounded by forests and fields. Picnicking, boat rentals, and ​trails are just some of its recreational opportunities. A restored 19th century cabin and a self-guided path interpret the history of the area. Over 50 miles of trails are open for hiking, horseback riding and bicycling which wind through a variety of habitat.​​

Note: Swimming and wading are not permitted in Clopper Lake at Seneca Creek State Park. The closest Maryland State Parks with lifeguarded lake swimming are Cunningham Falls State Park and Greenbrier State Park. Wading is permitted at your own risk in Great Seneca Creek, the free flowing creek which runs the length of Seneca Creek State Park.

Other Things to Know!

Disc Golf Course

​The Clopper Day-Use Area is home to one of the best disc golf courses in the Mid-Atlantic. With 32 acres and 27 holes (three nine-hole circuits) the Seneca course provides a popular pastime for families and groups. Each circuit spans a range of forested and open land.

The three courses start from a central location close to parking. Dual tees and multiple pin placements encourage new players to join more experienced friends and family. Plenty of benches around the course invite breaks to sha​re tips.

Playgrounds​

Nature Play Space
Balance, build, climb, connect, and create in our new nature play space at Oriole Picnic Grove. This imagination-centered play area is created from giant oak tree trunks, locust tree logs, and other all-natural materials. The idea of the play space and all of the work was done in-house by park staff, using the talents of our park technicians and park rangers.

Play as you Picnic
Quail Ridge and Chickadee Picnic Areas offer playground areas with climbing features and small slides close to picnic benches.

Agricultural Opportunities

Part of the Maryland Park Service mission is to promote the management of natural and cultural resources to ensure the continuing benefits for present and future generations, and farming is an important component of that. Agriculture is one of the central themes in Maryland’s rich and complex history and remains an important part of our state’s culture. It helps maintain wide open spaces and provide pastoral views that have remained unchanged despite surrounding development. Agricultural land use can also provide important food for wildlife and provide locally sourced food for nearby communities. In areas of Seneca Creek State Park where agriculture can coexist with passive recreation, the Maryland Park Service leases out lands that contain prime agricultural soils and have a history of being farmed to interested farmers for short-term agricultural use.

Are you interested in farming at Seneca Creek State Park? See the list below for agricultural lands out for bid:


If you’d like to submit a bid for leasing one of the above agricultural properties, please fill out the hyperlinked form for the property of your choosing and return either via mail or in person by 12:00pm April 13, 2024, to:
