The Great Falls Overlook Trail offers awesome views of the Potomac River as it roars through Mather Gorge. Accessible via the C&O Canal path, the best parking is at the Great Falls Tavern, with a large lot nearby. From Olmsted Island, there is a quarter-mile walk across bridges and boardwalks that takes hikers to the overlook. The trail, which crosses the river’s floodplain, is handicapped accessible, though dogs are not permitted. For fewer crowds, it's best to visit early in the morning, around 8 a.m.

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.

This is a spectacular waterfall on the Potomac River. Water gushes over a series of jagged rocks and flows through the Mather Gorge. The falls are surrounded by an 800-acre park of the same name – a lovely place to go exploring! 15 miles (24 km) of trails run through the park.
