Sleepy Creek is a tributary of the Potomac River. It is the most beautiful of the four streams in the Eastern Panhandle. The creek flows through woodlands, passed red shale cliffs and rock formations. This section is fairly smooth with some small rapids. At Johnson Mill the river turns left and plunges 6 feet over a natural dam. The hole at the bottom can be dangerous so be sure to scout this section. This creek is strictly a wet weather run.
