Chilhowee Mountain is a low ridge at the outer edge of the Great Smoky Mountains that stretches between the Little Tennessee River (specifically Chilhowee Lake) to the west and the Little Pigeon River watershed to the east. While not part of the Great Smoky Mountains National Park, the mountain's crest is traversed by the westernmost section of Foothills Parkway. While the mountain is 35 miles (56 km) long, it rarely reaches a width of more than 3 or 4 miles (6.4 km).
