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.
Popular, go early. Arrive before 8:30 am if u want a quiet trail and good parking on the weekend. Hiking boots recommended but not necessary. Went on a Late Sept. saturday morning at 8:15 from the middle of the trail. It took two 30 year old semi-fit women 2 hours to do part A (1.7 miles). Up and down and rocky. Another hour to see the outlook of the Great Falls was nice, too but its probably not that 'Great' if you've seen other places.
