Our Mt. Graham International Observatory tours start here at Eastern Arizona College’s Discovery Park at 9:00 am. We arrive back here at the campus at approximately 5:00 pm, so it’s an all-day adventure!

There are only daytime tours (no night time sky gazing). We will show you the Vatican Advanced Technology Telescope, the Arizona Radio Observatory, and the Large Binocular Telescope which is currently the largest, most powerful telescope in the world!

Tickets are non-refundable except for cancelations due to weather and fire.
