Bluemont is an unincorporated community in Loudoun County, Virginia located at the base of Snickers Gap in the Blue Ridge Mountain. As of 2010, the Bluemont postal area had a population of 2,834. At 680 feet (210 m), it is the highest community in Loudoun County. Originally named Snickersville, Bluemont changed its name to attract Washingtonians out to it when a predecessor of the Washington and Old Dominion Railroad was extended to the town from Round Hill. It is located on Virginia Route 7 just west of the incorporated town of Round Hill. Every fall it is home to the Bluemont Fair.
A nearby landmark is Mount Weather, an operations and training facility above ground for the Federal Emergency Management Agency and is rumored to contain an underground facility designed to house or replace the American government in the case of nuclear warfare.
