Great hike to see the historic Pump Station ruins and great view of the river with lots of rocks there. We continued west on the trail and kept going on the Laurel Trail until we were across from Bobbit Hole (see the chimney ruins). The trail to that point was up and down ... sometimes along the river and sometimes branching away a bit. At the chimney ruins, there is a trail that goes down to the river where we were able to cross to north side of river by hopping rocks and then walked east on the Bobbit Hole trail and then Cole Mill Trail. We kept going east Pea Loop and Dunegun loop trails until we were across from the Pump Station trail, Crossed the river again, rock hoping, and then returned to the Pump Station parking. Fun hike.
