Kitt Peak National Observatory is on a sky island south of Tucson about 35 miles. Take the tour that is offered it will give you a lot of insight on what is being done here and you also will be able to get inside of the telescopes. The tours vary. We had one to the 4 meter scope but I have also taken one to the solar scope. A picnic area is available and will give you some nice photographic opportunities. Great for children to see.
