Upon completion, the Justin P. Wilson Cumberland Trail State Park -- the state's only linear park -- will be 300 miles, cutting through 11 Tennessee counties from the Cumberland Gap National Historic Park on the Tennessee-Virginia-Kentucky border, to the Signal Point near Chattanooga.  The Cumberland Trail wanders among the remnants of the Cumberland Mountains that once rose as high as the Rockies. The trail represented a barrier to all who dared push through storied gaps westward onto and over the Cumberland plateau. It now provides a linkage north to south, forming natural connections and opportunities for scenic vistas and curious geological formations.
