After entering Barren County, it meets KY 1324 at Temple Hill.
KY 63 continues northwest to Glasgow, traversing the Louie B. Nunn Cumberland Parkway via an overpass.
The route ends with U.S. 31E Business just south of the Barren County Courthouse.
A few KY 63 trailblazer signs are posted in a few locations in that city.
Most of the KY 63 corridor between Tompkinsville and Glasgow is recognized as a Kentucky Scenic Byway, which signifies that KY 63 provides a scenic drive through most of its course in Monroe and Barren counties.
