Trinity opens to the public on the first Saturday of April and October. Fly to Albuquerque, New Mexico, then connect (or drive) to Alamogordo. Your visit will be much enriched if you prepare for it by reading Richard Rhodes’s Pulitzer Prize-winning The Making of the Atomic Bomb (Simon & Schuster, 1986).
