Long Hunter State Park is a state park in Davidson County and Rutherford County, Tennessee, located in the southeastern United States. The park is mostly situated along the eastern shores of Percy Priest Lake, an artificial lake created by an impoundment of the Stones River.
Long Hunter State Park comprises three lake sections — Baker's Grove in the north, Couchville at the center, and Bryant Grove to the south. All three sections are connected by narrow strips of land. The park also manages Sellars Farm, a state archaeological area near Lebanon to the east.
The West Fork of Stones River flows northward from its source in the hills around Rock Springs, passes through Murfreesboro and Stones River National Battlefield, and merges with the East Fork of Stones River near Smyrna. The East Fork flows westward from its source atop Short Mountain, at the edge of the Highland Rim, and passes north of Murfreesboro. The confluence of these two rivers forms Stones River proper, and marks the southern extreme of J. Percy Priest Lake.
Stones River's J. Percy Priest Lake impoundment stretches for approximately 22 miles (35 km) between the confluence of the West Fork and East Fork to the south and the J. Percy Priest Dam near Donelson to the north. Downstream from the dam, Stones River winds its way through a series of bends toward its mouth along the Cumberland River, just east of Nashville. Long Hunter State Park is officially located in Hermitage, a suburb of Nashville.
Tennessee State Route 171 follows Mount Juliet Road south from Interstate 40 to the park's boundary. The two roads then split, with TN-171 continuing west along Hobson Pike to the park's Couchville section, and Mount Juliet Road (now South Mount Juliet Road) continuing south to the park's Bryant Grove section. Granny Wright Road, which intersects TN-171 just north of its split with Mount Juliet Road, accesses the Volunteer Trailhead and the park's Bakers Grove section.
