Stretching beyond the National Mall in all directions, there are miles of squares and embassies, flowers and gardens, museums and stately statues.  The Potomac River influences many elements of the city, and offers chances to go canoeing and sculling.  The C&O Canal and its towpath offer a soothing environment to walk, jog, bike ride and refresh the soul.  The National Zoo is a popular place.  Georgetown is a fascinating section of the city, with its university, wealthy homes and a few remaining cobblestone streets.
