Radnor Lake Natural, situated on 2,000 acres of forested land, provides hikers with 10 miles of well-manicured trails. On a Saturday in October it can be a mad house, as this is the most popular hiking area in Nashville. But because of its proximity to downtown, it is a wonderful venue to get out before or after work for a beautiful hike. This natural area provides a variety of scenic spots and a diversity of natural habitats, including the woodlands, lake, and streams. There is an abundance of wildlife and plant species native to Middle Tennessee, and Radnor is well-loved by locals as a place that provides scenic, biological, geological, and passive recreational opportunities, not available in such close proximity, in other metropolitan areas of Nashville's size. There is an 80-acre man made lake in the hills just south of town. One of the trails, Gainer Ridge, ascends to almost the highest point in Davidson County, which is a whopping 1,100 feet. You can make a really nice loop out of Gainer Ridge trail, by doing a ridge walk and then dropping back down across Otter Creek Road. Radnor's focus is conservation, and therefore does not allow trail running, nor is paddling allowed on the lake.
