Get onto the NNE area of the Beltway (a circular highway that runs all the way around DC). Take exit 25-South from the Beltway onto Route 1 (also known as Baltimore Ave). This exit is immediately to the east of the Beltway/I95 interchange.
Continue about 2 miles south on Route 1. The main entrance to the campus is on your first right (on Campus Drive) after you pass Jerry's subs and pizza.
If you are coming from DC, you might find it easier just to go north on Route 1. This does involve a fair bit of traffic, traffic lights, and confusion, so it is not particularly recommended for people from out of town.
Coming from the south, once you get into College Park, there will be traffic lights at Knox Road, College Ave, Rossborough Drive, and Campus Drive. Turn left on Campus drive.
