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. Nearby, the Schaeffer Farm Trail Area offers 12 miles of marked trails for hiking and mountain biking. For the more adventuresome hiker, the 16.5-mile Seneca Creek Greenway Trail follows the entire course of the creek. About mid-May through June, the Schwartz peony gardens and field plants are in bloom.
High usage areas near Riffle Ford Road and relevant trails may be inadvertently closed through winter 2016/2017 for sewer line maintenance. There will be Washington Suburban Sanitary Commission (WSSC) work along the Greenway Trail, and upstream along Long Draught Creek through Mink Hollow Trail. Work may close the trail to park users, to be indicated by trail entrance signs and barricades. The WSSC will be carrying out the projects. For further information and updates, call the commission at 301-206-7363.
