1) Experience the serenity of the monuments at sunrise. Start with the sun behind you at the Grant Memorial (just in front of the U.S. Capitol), and jog the 2 miles down to the Lincoln Memorial, passing the Washington Monument and the World War II Memorial along the way.
2) Make a power play and start a game of Frisbee on the National Mall or a game of volleyball at one of the pits at Potomac Park.
3) Grab your hiking boots to trek your way down the C&O Canal Towpath, which traces the Potomac from Georgetown to Cumberland, Md.
4) Head to Gravelly Point, a park area off the George Washington Memorial Parkway and Mount Vernon Trail, to watch the planes take off from Reagan National Airport.
5) Let DC's green space surprise you with a visit to the National Arboretum. While you're there, take in the beautiful colors and see the pillars from the original U.S. Capitol, which was burned during the War of 1812.
6) Browse through the National Gallery of Art's Sculpture Garden to take in art and fresh air at the same time. The garden features seating for visitors and a fountain that turns into an ice rink in the winter.
7) Rarely travel without Fido? Bring him to Lincoln Park on pet-friendly Capitol Hill to make nice with the neighborhood's four-legged friends. Art and Soul at the Liaison Capitol Hill lists Bowser Beer on its dog-friendly patio menu.
8) Spend just $5 per vehicle, or $3 a person if you go on bike, via the C&O Canal Trail to explore nature in Great Falls Park. These 800 acres of scenic parkland with hiking trails, cascading rapids and waterfalls are located just beyond the Beltway.
