When we visit the small Middle Tennessee city of Manchester, it’s usually to visit family; my in-laws live in the city about an hour’s drive south of Nashville. If you’re familiar with big music festivals you’ve probably heard of Manchester’s annual Bonnaroo music and arts festival. But Manchester, Tenn., is also home to an archaeological find: Old Stone Fort State Park. But Old Stone Fort State Park isn’t just a place to discover an ancient place once important for Native Americans. It’s also a fun hiking adventure filled with beautiful waterfalls along the Duck River.
