Kitt Peak National Observatory

Few other places in the world can claim as many clear skies as southeastern Arizona, and astronomers have taken advantage of this fortune since 1958. Kitt Peak has the largest collection of optical telescopes in the world—24 optical and two radio telescopes—and there’s always science in progress on the hilltop campus. Visitors can take advantage of either the self-guided walking tour or the guided walking tours offered three times a day, each featuring a different telescope. The observatory is about a 90-minute drive from downtown Tucson on the Tohono O’odham Reservation.

I-19 south, Hwy. 86 west, Jct. 386, approximately 90 minutes, 520.318.8726.
