Summit Visit Information:

Curious about astronomy on Mount Graham? Do you wish to see the telescopes on Mount Graham!?

Eastern Arizona College's Discovery Park Campus is the the official visitor's center for the telescopes on Mount Graham. They conduct weekend tours of the Mount Graham International Observatory. Weather permitting, the tours begin in mid-May and go through October. Because permits are required to enter the endangered red squirrel refugium, advance reservations are required.

The tour features a trip up scenic Mount Graham, focusing on the mountain's rich geology, history, and diversity of life; a lunch near the summit of the mountain; and a guided tour of the observatories -- The Submillimeter Telescope, the Vatican Advanced Technology Telescope, and the Large Binocular Telescope!

The Discovery Park tours start and end at the EAC Discovery Park Campus, as shown in the map below:
