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 Nation's Capital.
The Washington, D.C. area has a four-season Mid-Atlantic climate. Summertime is warm and humid, while winter can be cold and snowy. Precipitation averages 2-4” monthly, year-round.
