55 Best Things to Do in Washington DC
"Hugging the banks of Rock Creek on its meandering route down to the Potomac is a big urban park, spreading over more than 2,000 acres and drawn up in 1890. Previously this land had been the site of a chain of batteries defending Washington in the Civil War. The valley is often steep, and blanketed with beech, oaks, dogwoods and cedars, while some of Washington’s favourite historic bridges cross the creek, like Lauzun’s Legion, the Duke Ellington Bridge, the Daft Bridge and the Dumbarton Bridge."
