Reston, Virginia is a great, central location to see sites in the Northern Virginia & DC metropolitan areas.  Just 20-25 miles west, you can experience the small town charm of Leesburg & awesome shopping at the Leesburg Outlets.  You can also experience great scenic views down route 15 as you venture out towards Warrenton.  If you head north on route 15, you'll head towards the historic Harpers Ferry where you can partake in camping, biking, hiking, shopping, or tubing.  Heading west on route 7 from Leesburg will put you near West Virginia, where it is wonderful!  The mountains are gorgeous & you can look up adventure companies who will take you on white water rapid cruises, canoe rides, kayak rides, tubing, rock climbing, horseback riding, and any other 'fun in the sun' type of activity you can dream up.  Look here for some adventures in West Virgina, just under an hour from Reston.

Right in the heart of Reston, there is plenty to see & do.  If you love to road bike (the bicycle kind), the WO&D trail is a paved pathway for bikers, walkers and runners.  No cars allowed.  Just be sure to brush up on your riding etiquette before heading out.  "On your left" Also, be sure to check out the Reston Town Center for movies, shopping, summer concerts, and dining.  In the winter time, the pavilion that houses the summer concert series, turns into an outdoor ice rink.  Check out the link below.

Another great local spot in Reston for good dining, serene views, used books & the occasional swan, is Lake Anne of Reston.  When you don't feel like the hustle and bustle of Reston Town Center, check out Lake Anne where everything is a little more laid back.

If you're to experience a piece of history, travel 20 miles to Washington D.C. to see monuments, great culture, parks, and an occasional famous person lurking around for some D.C. based weekly tv program.

If you like Jazz, D.C. has some great venues:

One great option is the Smithsonian Jazz & Cafe at the Natural Museum of History, which you'll see in the list on the link above.  They have an IMAX theatre there & on some evenings, if you buy tix to the IMAX, you get into the Jazz Cafe for free.  The food there is expensive, but really yummy.  The jazz artists are top notch.  Another great local spot is "Utopia" on the U-Street corridor.

 Whatever you do, enjoy your stay!
