Mount Graham International Observatory Visitor Center

Eastern Arizona College's Discovery Park Campus is the official visitor center and starting point for seasonal Mount Graham International Observatory tours. Weather-permitting weekend tours run from mid-May through October with advance reservations required for red-squirrel-refugium permits; the experience covers Mount Graham's geology and history, a summit lunch, and guided visits to the Submillimeter Telescope, Vatican Advanced Technology Telescope, and Large Binocular Telescope.
