About the Park

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, trails and a tire playground 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.

Mountain Biking

​​​ ​

Schaeffer Farm Trail System

SERVICE ADVISORY
The Schaeffer Farms trail network is CLOSED TO MOUNTAIN BIKING until mid-March 2024. This winter closure prevents damage to the trails during the winter freeze-thaw season, and helps us keep the trails in prime condition during the best riding months.
During this winter biking closure, the Schaeffer Road trailhead parking lot is also gated and closed.
​ ​The Seneca Ridge Trail and Seneca Bluffs trail remain open for mountain biking all year as an alternative to Schaeffer Farms for MTB riders.

Mountain Biking in Seneca Creek State Park

​Schaeffer Farm is the hub of a trail system unique in Maryland. The trails at Seneca Creek State Park provide the backbone of a network that extends into most of the upcounty area. Configured in a series of loops, you can enjoy as few as four miles or go for an all-day adventure. It is possible to do a trail loop stretching 60 miles or more when you leave the trailhead. Linking the Seneca, Muddy Branch, and Potomac watersheds, visitors can journey from Schaeffer to Damascus to the Potomac and back.

One of these larger loop​s has been recognized by the International Mountain Bicycling Association as one of the best and most important routes in the country.​​
