It is approximately 2.7 mi long and flows through Pine Township.

Plantlife common in the vicinity of the stream include hemlock trees. Trout inhabit the stream itself.

Course
Devil Hole Run begins in a small pond in Pine Township, a few hundred feet from the border between Columbia County and Lycoming County. It flows south-southeast for a few tenths of a mile before turning south. After a few hundred feet, the stream turns south-southeast again, crossing Wolf House Hollow Road. Its valley becomes deeper as it continues downstream. After at least two miles (three kilometers), it receives its only named tributary, Kline Hollow Run. At this point, the stream turns south for a few tenths of a mile, crossing Devil Hole Run Road. It then exits its valley and turns southeast. A short distance further downstream, it reaches its confluence with Little Fishing Creek on the border between Pine Township and Greenwood Township.

Tributaries
Kline Hollow Run, which joins Devil Hole Run in the latter stream's lower reaches, is the only named tributary of Devil Hole Run.
