This long loop hike around Prince William Forest Park begins from the Visitor Center and follows the South Valley Trail along the edge of the South Fork Quantico Creek. Passing by an old pyrite mine, take a brief detour on Pyrite Mine Road and then veer right on the Cabin Branch Mine Trail. After a long trek northward on the North Valley Trail past the lake, the trail then intersects with Taylor Farm Road and progresses towards the Taylor Farm site. The remainder of the journey follows the High Meadows Trail until it hits the creek and once again becomes the South Valley Trail on its way back to the parking area. Hikers will enjoy numerous views of the tiny cascades in Quantico Creek, the dismantled buildings of old mines and dwellings, as well as the quiet solitude of well-kept forest roads that glisten with fall colors in the autumn.
