High Bridge Trail is 31 miles long and ideally suited for hiking, bicycling and horseback riding. Once a rail bed, the trail is wide, level and generally flat. Its finely crushed limestone surface and dimensions make it easy to enjoy. The park’s centerpiece is the majestic High Bridge, which is more than 2,400 feet long and 125 feet above the Appomattox River. It is the longest recreational bridge in Virginia and among the longest in the United States. High Bridge, a Virginia Historic Landmark, is on the National Register of Historic Places.
