Go up the stairs or elevator to the third floor. Turn left and you will be facing an unmarked door at the end of the hall. Go through that doorway and out onto the roof. Walk to your right, and you will see the door to the observatory dome around the corner.

General directions to campus are available on the Visitor's Dashboard. Some mapping software will get you directly to our parking lot via Dupont Parking, Swarthmore, PA 19081.
