Away from the falls, you can walk for miles along the canal, as well as along several more challenging, rocky trails along the river. (See the park map and trails description.) We'll often stop by the falls, then hike the Billy Goat A trail and come back on the canal, which is a loop of about 4 miles (see this description). April through October, you can ride on a boat in the canal as it goes through the locks of the canal. Uphill from the canal, there are trails through the woods to an old gold mine -- it's not much to look at, but has an interesting history.
Beyond the overlooks, you'll find miles of hiking on this side of the river as well. (See the park map.) To the north, you can walk to Riverbend Park; to the south, you can catch the Difficult Run Trail, which follows that river for 15 miles through Fairfax County. See this description of a 5-mile hike that combines a stretch of Difficult Run, the path along the Potomac as it passes through Mather Gorge, the overlooks of the falls, and a return through the middle of the park on the Swamp Trail.
Bikes: In Maryland, bikes aren't allowed on any of the hiking paths. But you can ride to your heart's content on the C&O Canal -- you'll just need tires that can take the rough path. In Virginia, five miles of trails are open to bikes: the Old Carriage Road, Ridge, and Difficult Run trails. Biking is not permitted on the River, Patowmack Canal, Mine Run, or Matildaville Trails.
Climbing: The cliffs along the river are a popular rock climbing destination. This site has descriptions of the routes on the Virginia side.
Swimming is prohibited. Several people have died swimming in this section of the Potomac.
Fishing is allowed, with the appropriate state license.
