This site is a monument to Tennessee Valley Authority engineering. Water is pumped from the Tennessee River into a 528 acre man-made lake atop the mountain, where it is gravity-fed to turbines within the mountain to generate electricity. A tour of the facilities is available by taking an elevator deep underground. From the mountaintop visitor center, an observation deck provides a panoramic view of the beautiful Tennessee River Gorge. The area around Raccoon Mountain is a state-designated Wildlife Observation Area. Miles of hiking trails loop around the lake provide quite a nice hike, although they are also mountain biking trails so watch for bikers.
The mountaintop is home to White-tailed Deer, Woodchucks, Gray Fox, and, of course, Raccoons. Visitors may see migrating hawks, falcons and eagles in spring and fall. The lake is a good bet for Bald Eagles and vultures during winter. A walk around a nearby picnic area may reveal many small land birds. In fall, hawk migration can be seen with passing Cooper's Hawk, Broad-winged Hawk, Sharp-shinned Hawk, Red-tailed Hawk, Osprey, and Northern Harriers. The most compelling wildlife attraction of the area is a large wintering population of Bald Eagles, which can be sighted from the overlook as they hunt in the woods and waters.
Common Loons may be spotted here during the winter.
