Guided Daytime Tours of Kitt Peak National Observatory will restart on Friday 22 September. Spaces are limited to 24 guests per tour. Please make your reservation in advance to guarantee a spot.
Kitt Peak is very much alive during the daylight hours and offers a variety of activities to enjoy.
During the summer, the mountain is a great place to beat the desert heat.
Each tour, led by a docent, visits one of the large, historic telescopes of Kitt Peak. Telescopes are occasionally closed to the public for maintenance. The Visitor Center does its best to alert visitors of any changes to the regularly scheduled tours.
