At Great Falls, the Potomac River builds up speed and force as it falls over a series of steep, jagged rocks and flows through the narrow Mather Gorge. The Patowmack Canal offers a glimpse into the early history of this country. Great Falls Park has many opportunities to explore history and nature, all in a beautiful 800-acre park only 15 miles from the Nations Capital.
I gave it 3 stars but it's surely at least 4 stars with Spring or Fall foliage but certainly an enjoyable trail. I'm not a fan of broad gravel paths and found myself on some today. But otherwise the trail offered the type of diversity I do enjoy. It had some natural surface (other than gravel), a little elevation gain, some rock scrambling and the river and its soothing sounds.
Definitely would rate moderate if you're comfortable with climbing and jumping on rocks. There is a sign that warns you when the trail becomes more difficult-and you can easily turn around if you are not comfortable with jumping and scaling rocks. Beautiful views and interesting trail over all.
