It runs southwest to northeast, from just south of Knoxville to Kingsport. The southern segment of Bays Mountain is relatively low in elevation. In some places it essentially merges with the surrounding plains, especially where it is bisected by the French Broad River and the Nolichucky River. The northern segment of Bays Mountain reaches higher elevations, averaging above 2,000 feet with peaks reaching up to 3,000 feet. It is not a single ridge but rather a series of closely related ridges, some of which have names of their own. The highest peak is Chimneytop Mountain, a spur ridge south of the main Bays Mountain ridge.
