PA 507 begins at an interchange with I-380 in Coolbaugh Township, Monroe County, heading northeast on a two-lane undivided road. Immediately after beginning, the route intersects the southern terminus of PA 435. A short distance later, the road enters Lehigh Township in Wayne County and becomes Main Street, running through dense forests with some homes to the north of Gouldsboro State Park. PA 507 curves to the east and heads through wooded areas of homes, entering the community of Gouldsboro, where it crosses a Delaware–Lackawanna Railroad line. The road continues north-northeast through dense forests with some private residential developments.

PA 507 continues northeast through more forests with some housing developments, curving east and coming to an intersection with PA 191. Here, the route turns north to form a concurrency with PA 191, heading north on Main Street through wooded areas with some fields and homes to the west of Wallenpaupack Creek. The road curves to the north-northeast and intersects the northern terminus of PA 447 in Newfoundland. The two routes pass through rural residential and commercial development before PA 191 splits to the northwest and PA 507 heads northeast as Lake Wallenpaupack Road.

PA 507 crosses the Wallenpaupack Creek into Greene Township, Pike County, running through woodland with some development and turning to the north-northwest.
