This loop starts out as a smooth singletrack along the water. Then it becomes a wide path with moderate amounts of roots before it turns left and climbs up a hill. Overall the trail is pretty smooth with only a few roots and occasional rocks. The trail loops back to the entrance at the soccer fields.
