Kitt Peak Visitor Center


Kitt Peak National Observatory, on the Tohono O’odham Reservation in Arizona, USA is home to one of the largest arrays of optical and radio telescopes in the world. Alongside its primary role of conducting ground-breaking astronomical research, Kitt Peak is also host to a Visitor Center where daytime guided tours and a variety of evening stargazing programs are available. Please note that no one may visit after dark for any purpose unless registered for one of our evening programs.

  • The Visitor Center is open every day from 9:00 AM to 3:45 pm for daytime visitors and volunteer-led tours.

The Visitor Center is closed on Thanksgiving Day, Christmas Day, and New Year’s Day. Sometimes it is closed as a result of unforeseen circumstances, such as environmental events, that are beyond control, so please check before ascending the mountain.

The Kitt Peak Visitor Center is your first stop on any visit and your springboard to informative daytime tours, nighttime stargazing and telescope viewing programs, fascinating exhibits, a terrific gift shop, and beautiful panoramic mountain top views!
