Radnor Lake State Park is a 1,332-acre park and protected natural area that maintains over 6 miles of hiking trails in a shaded, ecologically diverse setting. Nature enthusiasts at the park have observed herons, owls, water fowl, turtles, frogs, mink, and otter, in addition to numerous plant species. The Park is Tennessee's first Natural Area, earning this status in 1973 thanks to public outcry against plans to develop it. The Historic Valve House Trail opened in 2011 to walk visitors through the history of the area. From 1914 to 1917, Louisville and Nashville Railroad Company had a dam constructed on Otter Creek. This dam led to the creation of Radnor Lake, which supplied water for L&N's steam locomotives.

  • Cast-iron pipe: more than 4 miles of underground pipes carried water (up to 1,000,000 gallons daily!) from Radnor Lake to the railroad yards. No pumps were needed, as the system worked using gravity.
