Prince William County is in Northern Virginia.
The closest major airport is Ronald Reagan Washington National Airport (IATA: DCA), although Manassas also has its own, for private planes: Manassas Regional (IATA: MNZ).
Otherwise, the main artery is without question I-95. Interstate 66 also crosses through the northern part of country.
Sightseeing in Prince William County is overwhelmingly military-related: the National Museum of the Marine Corps and Manassas Battlefield National Park, both of which attract a lot of residents and other out-of-state tourists coming down from D.C.
The Potomac Mills Outlets are the other big regional draw, again bringing in the visitors from D.C.
