New River Trail State Park

New River Trail State Park is off I-77 exit 24, then 1.5 mi. n. on US 52. Virginia's longest linear park parallels the New River for 39 of its 57 miles. The trail for walkers, bicyclists and horseback riders follows a former railroad track through Grayson, Carroll, Wythe and Pulaski counties. A fortresslike shot tower, built in 1807, was used to make lead ammunition. Metal was melted and poured through sieves from the top, falling 150 feet into a kettle of water. The 75-foot-tall tower was made of local limestone; its walls are 2 feet thick.
