The River Trail is a 1.5-mile, trail that follows the Potomac River along cliff tops, offering great views of Mather Gorge. The cliffs range from 25 to 75 feet in height, and hikers may spot vultures or great blue herons. Some sections require rock scrambling, especially between the Canal Cut and Cow Hoof Rock. This trail can be dangerous in wet conditions, as lichen and sand can make the rocky areas slippery. After heavy rain, parts of the trail flood, and in winter, they can become icy.
