## Course

Kline Hollow Run begins in a valley in Jordan Township, Lycoming County, a short distance south of Richarts Grove. It flows south for a few hundred feet before turning southwest. The stream then turns south-southeast and passes through a pond. Several tenths of a mile further downstream, it exits Jordan Township and Lycoming County.
Upon exiting Lycoming County, Kline Hollow Run enters Pine Township, Columbia County. It continues flowing south-southeast for more than a mile, receiving an unnamed tributary, before eventually gradually turning south. The stream's valley deepens as it flows south for more than a mile, passing by Huckleberry Ridge. Near the southern edge of Huckleberry Ridge, the stream reaches its confluence with Devil Hole Run.
