Here, the name of the road becomes West State Street and it passes homes, reaching a junction with US 222. At this point, US 222 becomes concurrent with PA 372 and the road is lined with more residences. In the center of Quarryville, US 222 turns to the south and PA 372 continues along East State Street through the commercial downtown. The route passes homes and businesses in the eastern part of Quarryville and intersects the northern terminus of PA 472. The road comes to a bridge over the Enola Low Grade Trail and leaves Quarryville for Eden Township, where the name changes to Valley Road. At this point, the route enters the Pennsylvania Dutch Country of eastern Lancaster County, which is home to many Amish farms. PA 372 heads east-northeast through farmland with some wooded areas and homes. The route continues into Bart Township and passes through more rural land before it reaches an intersection with PA 896 in the community of Green Tree. At this point, PA 372 turns north onto PA 896 and the two routes run concurrent through a mix of farms and homes along Georgetown Road.
