Aside from simply admiring the ubiquitous vistas of the Appalachian Mountains, you might also want to see:
Hagerstown is only 80 minutes away from Washington, D.C., Baltimore, and Harrisburg. The main interstates running by the city are I-81 and I-70, each of which have multiple well-signed exits for Hagerstown.
Greyhound [1] and Atlantic Coast Charter Buses [2] both have stops in Hagerstown.
If you're feeling adventurous, you could also fly in via Hagerstown Regional Airport, located 8 miles outside of the city, but you'll need to bring your own plane, as commercial service has ceased as of October 2007.
