Loudoun County

Loudoun County sits in northern Virginia, stretching from the Potomac River westward toward the Blue Ridge Mountains. The landscape shifts from rolling farmland and vineyards in the west to more developed suburbs closer to the capital.

The territory was formed in 1757 when it separated from Fairfax County, taking its name from John Campbell, Fourth Earl of Loudoun. Campbell served as the royal governor of colonial Virginia during the Seven Years' War.

Local wineries invite travelers to taste wines from grapes grown in the rolling hills between Washington and the mountains. Horse farms and stables dot the countryside, reflecting a way of life that blends rural tradition with modern suburban growth.

Most points of interest lie along the main roads heading west toward the mountains and vineyards. The area is easiest to explore by car, as public transit options are limited outside the eastern suburbs.

In just a few decades, the area shifted from mostly farmland to one of the fastest-growing residential zones in Virginia. Today it is home to over 420,000 people, though it remained largely rural until the late 20th century.
