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 river. During May, the Schwartz peony gardens and field plants are in bloom.

Outside of the little trash on the ground, it's a very good walk

the trail is beautiful and large enough that you don't run into a lot of people.

Nice trail. Well traveled. Shady, mostly flat with nice scenery. Disappointing amount of trash on the trail hence the 3 stars.

Peaceful and quite. Some gorgeous spots - take in the scenery. Mostly shaded and well travelled trails with wide clearings. You can veer off the blue and at time stay very close to the shore.

I use to run this trail and it is peaceful and beautiful.

Great trail around the lake! Dogs loved it, as did I!

Rating should be increased from Easy to Hard. Trails need to be cleaned a little, but very nice nonetheless.
