Radnor Lake State Natural Area is located in Davidson County in the midst of the Overton Hills, south of Metropolitan Nashville in the Oak Hill Community. This natural area provides a variety of scenic spots and a diversity of natural habitats ranging from the lake, to streams and placid sloughs. It even has some of the highest hills in the Nashville Basin.
Wildlife is amazingly abundant.
One can observe geese, herons, coots, and other birds as well as many species of salamanders, frogs, snakes, lizards, turtles, and mammals. Hundreds of species of wildflowers, mosses, fungi, ferns, and other lesser plants as well as trees, shrubs, and vines add to the natural ecological diversity of the area. Radnor's geology is also fascinating and complex. The rocks, which form its hills and valleys, were deposited on the floor of a shallow, tropical, inland sea 500,000,000 years ago. The 85-acre lake for which the site is named was impounded in 1914 by the Louisville and Nashville Railroad Company to furnish water for steam engines and livestock at nearby Radnor Yards.
