Scotts Run Nature Preserve Professional Review and Guide
"Out-of-sight Scotts Run Nature Preserve, on the Potomac River very near the beltway, is well supplied with flora, fauna, breathtaking cliff and river views, a waterfall, and rapids, with a variety of hiking trails.
This hike loops through thickly wooded uplands and reaches the river in three places. It’s hilly enough to provide about 420 feet of elevation change. There are trailside maps, and blazes are usually easy to spot, but take a map and plan your route before you go. Also, watch for signs on the Potomac Heritage Trail, which traverses the shoreline; it can be muddy, rooty, and rocky."
