The route is a two-lane undivided road that runs through rural portions of northern Lackawanna County.

PA 632 was designated along its present alignment in April 1961 as part of construction of I-81 so that the latter would interchange with state highways in Lackawanna County.

Outside of Dalton, PA 632 retains the moniker for a short distance, crossing under the former alignment of the Delaware, Lackawanna and Western Railroad that is now Norfolk Southern's Sunbury Line.

The route turns eastward then slowly southeastward and after an intersection with Miller Road, PA 632 becomes rural once again.

Along the southeastern stretch, the highway passes numerous residences and a cemetery before entering the hamlet of Green Grove, where PA 632 becomes the primary street, before leaving for a short stretch of rural homes and then into more residences, where the highway intersects with PA 247 south of Montdale.
