This is an old abandon railroad bed, that was taken over by the Virginia State Park system and converted into a beautiful hike, bike, and horse, trail. It goes over the Appomattox River and over the (hence the name) High Bridge.
High Bridge Trail is 31 miles long and runs through Cumberland, Nottoway and Prince Edward counties and the towns of Burkeville, Farmville, Pamplin City, Prospect and Rice.
