Little Roaring Creek begins on a hill in the southwestern corner of Mayberry Township, Montour County.

The creek flows through a valley for several miles, eventually turning north and slightly east.

It eventually leaves its valley and almost immediately reaches its confluence with the Susquehanna River.
