The more southerly branch of the stream (the official USGS source at 40°23′4″N 74°46′34″W / 40.38444°N 74.77611°W / 40.38444; -74.77611[2]) rises to the west of Hopewell, flowing east, turning south below Hopewell, and then east again to meet the more northerly branch (sourced at 40°24′57″N 74°46′18″W / 40.41583°N 74.77167°W / 40.41583; -74.77167).

This rises on the southern slopes of Sourland Mountain, cutting a valley that defines the west side of Pheasant Hill.

The combined streams then flow eastward, passing through the Bedens Brook Club and Cherry Valley Country Club to the south of Blawenburg.

Past Blawenburg, the twisting brook turns to the northeast, and Cherry Run enters from the south.

Turning eastward again, the brook passes under U.S. Route 206 and receives Pike Run before emptying into the Millstone River.
