After Nashville fell in 1862, the Federals wasted no time fortifying the city against attacks. One of the city's forts was Fort Negley, and most people think of this fort, with good reason, as an educational historic site. But with its great views and challenging hills, its also a good place to get the heart rate going with family-friendly hiking among the history.
There is a short paved loop trail around the base of the fort, plus raised boardwalks through the fortifications themselves. Historic markers tell the story of the fort's construction and detail its military features, which you can read before or after your run.
Parking is ample, but check visitor center hours before heading out. They vary by season and the park is not open past 4 p.m. many days.
