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.

New Point of Sale at Seneca Creek

Seneca Creek State Park is now using a new point-of-sale system at the park entrance, designed to make entry more convenient and allow visitors to pay by credit or debit card. Please note that a small vendor processing fee is added to cash and credit transactions made through the new system.

Paying with cash? Due to the nationwide coin shortage, the availability of coins for making change is limited. As a result, cash totals are automatically rounded to the nearest whole dollar. Amounts ending in 49 cents or less are rounded down, while amounts ending in 50 cents or more are rounded up.

For example, a total of $3.40 would be rounded down to $3, while a total of $3.60 would be rounded up to $4. Credit and debit cards are charged the exact transaction total.


PARQUE ESTATAL SENECA CREEK

El Parque Estatal de Seneca Creek cuenta con un nuevo sistema de punto de venta en la entrada del parque, diseñado para agilizar el acceso y permitir a los visitantes realizar pagos con tarjeta de crédito o débito. Tenga en cuenta que las transacciones efectuadas en efectivo o con tarjeta de crédito mediante el nuevo sistema están sujetas a un pequeño cargo por procesamiento del proveedor.

¿Va a efectuar el pago en efectivo? Debido a la escasez de monedas a nivel nacional, la disponibilidad de cambio es limitada. En consecuencia, el total a pagar en efectivo se redondea automáticamente al dólar entero más cercano. Los importes que terminan en 49 centavos o menos se redondean al dólar inferior. Los importes que terminan en 50 centavos o más se redondean al dólar superior.

Por ejemplo, un total de $3.40 se redondeará a $3.00, mientras que un total de $3.60 se redondeará a $4.00. Los pagos realizados con tarjetas de crédito o débito se procesan por el importe exacto de la transacción.

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 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 farm​ing at Seneca Creek? 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 October 30, 2026, to:

Trail System and Maps

Over 50 miles of trails are open for hiking, horseback riding and bicycling which wind through a variety of habitat in S​eneca Creek State Park. A detailed trail map can be purchased at the park office.

Mountain biking and horseback riding are very popular at Seneca Creek, and the Schaeffer Farm Trails are considered a favorite place to ride. The Maryland Park Service does not rent horses or bicycles, and only provides the trails as a means of recreation.
