Towering above the Sonoran Desert are the distinctive white domes of Kitt Peak National Observatory. This scattered group of buildings just outside Tucson might look unassuming but they are home to the world’s largest collection of optical telescopes. Visit the observatory to enjoy panoramic views from the summit, climb inside a working telescope and learn about astronomy.
Although it is overseen by the National Optical Astronomy Observatory and funded by the National Science Foundation, the observatory is open to the public. Take a guided tour, learn about the history of the facility and go inside a primary research telescope. Explore the McMath-Pierce telescope, the world’s largest solar telescope and the 13.1-foot (4-meter) Mayall telescope, the largest optical telescope on Kitt Peak.
Astronomy aficionados should take the comprehensive V.I.P. tour, which lasts for 4-5 hours and takes you all around the summit. If you want to do some stargazing, attend the Nightly Observing Program. Arrive in the late afternoon to catch the sunset and then explore the cosmos as night falls.
The Visitor Center has snacks and beverages for sale, but there is no café or restaurant on the mountain. Pack lunch for the family and sit at one of the picnic tables with a scenic view of the surrounding area. The Visitor Center also has a charming gift shop with a selection of books and souvenirs. Browse a selection of local wares, including baskets and jewelry, crafted by the region’s indigenous Tohono O’Odham people.
Kitt Peak National Observatory is 53.8 miles (86.5 kilometers) from Tucson. Rent a car and allow 90 minutes driving time to enjoy the scenic drive up the mountain.
