The Fred Lawrence Whipple Observatory (FLWO) is the largest field installation of the Smithsonian Institution Astrophysical Observatory. Since October 1968, the FLWO has been used as the site for experiments requiring extremely dark skies, dry climate, and good "optical seeing."
On Mondays, Wednesday, and Friday, from Mid-March thru November, there are all day public tours (reservation required) of the mountain top observatory. Elevation is 8550 feet so bring warm clothes. Cost $7 per adult, 6-12 $2.50 and because of the length of the tour no one under 6 is allowed.
The FLWO Visitor Center features displays and exhibits on astronomy and astrophysics, natural science, and cultural history. The Visitor Center is located at the base of Mt. Hopkins 35 miles (56 kilometers) south of Tucson.
