Radnor Lake State Park is a 1,332-acre park and is protected as a Class II Natural Area. The lake is manmade and was created by the Louisville and Nashville Railroad Company in 1914 to supply water for steam engines at a nearby location. Remnants of this operation, including a historic valve house, which can still be found on the property. Today, Radnor Lake provides an opportunity for outdoor recreation within just a few minutes of Nashville.
The popular 2.6-mile loop around the lake starts by following the Spillway Trail. After about 0.25 miles you will come to the first view of the lake. Continue straight along the Lake Trail for another 1.3 miles. Keep your eyes open for wildlife as deer and turkey can usually be found along this section of trail. The trail will then intersect with Otter Creek Road (which is closed to vehicular traffic at this point). Take a right and follow the road back to the parking area.
In addition to the loop trail, several more miles of hiking trails can be found at Radnor. Check out the 1.55-mile Ganier Ridge or the 1.18-mile South Cove Trail. Both of these trails are difficult and feature a good amount of elevation gain. Please note that no dogs are allowed, and jogging, running, and bicycling is prohibited on all trails except Otter Creek Road.
