Northern Virginia has always been closely tied with the nation's capital. This part of the state benefits from the history and the cultural aspects of Washington D.C., featuring famous museums, cemeteries, and the home of the first president of the United States.
Much of the north-eastern corner of Virginia was farmland until the period immediately following World War II, when government employment increased and the population around Washington D.C. began to grow. The area experienced another explosion in growth due to tech industry jobs in the early 90s. Today it remains one of the fastest growing areas of the country.
While Northern Virginia continues to expand, the region ranges from crowded planned cities with excellent shopping to soccer-mom suburbia, from ethnic neighborhoods full of authentic restaurants to the upper-crust style of the Hunt Country.

Amtrak provides train service on a regular schedule between points north and Washington, DC's Union Station. Washington DC's mass transit (WMATA) provides service to Northern Virginia on the Blue, Yellow, and Orange lines.
From the south, Amtrak provides twice daily service from Newport News, Virginia with a last stop in Alexandria prior to arrival at Union Station.
Taking Metrorail might be your best option - there are many stations within the Beltway (near Washington, DC, in other words), including one that emerges right outside the Fashion Centre at Pentagon City. It is also the easiest way to enter Washington, DC.
Driving can be convenient, unless you wish to enter Washington, DC, or cross the Beltway in either direction. The highways (I-395, I-95, I-495, and I-66) are extremely backed up during rush hour. The "Mixing Bowl" (the intersection of I-395, I-95, and I-495 south of Washington, DC) is especially notorious. Attempting to travel by road between 2:00 PM and 6:00 PM on any weekday (and, for that matter, on a weekend) is strongly discouraged.
