Great Falls Park

Great Falls Park, at 9200 Old Dominion Dr in McLean, Virginia, is a National Park Service site about 14 miles (23 km) northwest of downtown Washington, DC. Here the Potomac River narrows and drops over a rocky gorge in a series of cascades. The drive via the George Washington Memorial Parkway and Georgetown Pike takes 30 to 40 minutes, and a car or rideshare is the practical way to reach the entrance, since no Metro line serves the park directly. The transit fallback is the Metro Orange Line to West Falls Church followed by a rideshare of roughly $20-$30 USD. Entrance is $20 USD per vehicle, or $10 USD per person on foot or bicycle, valid for seven days. The park is organized around three overlooks and a network of trails. Overlook 1 and Overlook 2 are a short walk from the visitor center and give the best views of the main cascades, while the River Trail runs along the rocks for a closer sense of the gorge. The Patowmack Canal Trail follows the ruins of the canal George Washington helped promote, with remnant locks and a stone channel, and takes about 45 minutes at an easy pace. The visitor center has exhibits on the canal and the river and sells limited snacks. A good one-day arc is to arrive by 10 AM, walk to Overlook 1 and Overlook 2 first, then follow the canal trail and River Trail before a picnic near the visitor center. Visitors should head back before the late-afternoon traffic on the parkway. Food options inside the park are minimal, so bringing lunch is the usual advice. Spring offers high water and wildflowers, fall brings foliage, and summer can be hot with crowded parking on weekends. The river is dangerous: visitors must stay on marked trails and off the rocks, as drownings have occurred. Check nps.gov/grfa for closures before traveling, since parking fills quickly on fine weekends and the lot can close temporarily.
