Explore the Mayall 4-meter telescope with a docent-led daytime tour
90 Minutes
Guided tour, General Admission
Explore Kitt Peak during the day on a docent-led tour of the Nicholas U. Mayall 4-meter Telescope, including the inside and outside of this historic facility.
You’ll spend about 90 minutes walking between sites and climbing stairs at nearly 7,000 feet (2,096 meters).
This tour requires extensive walking and most facilities are not wheelchair-accessible. Strollers and carry-on infants are not permitted. Prices displayed do not include fees—clarify the fee amount with Greetwell before booking.
Cancel up to 48 hours before the tour date without penalty. With less than 48 hours notice, tickets are non-refundable and cannot be rescheduled. Full refund if the operator cancels the program.
Plan on extensive walking, stairs, and uphill sections. Most facilities on this tour are not wheelchair-accessible, and the Visitor Center’s ability to provide special accommodations is severely limited.
Expect extensive walking at nearly 7,000 feet (2,096 meters), including about 1/2 mile uphill and almost two flights of stairs.
Dress in layers for cooler temperatures and wind at the summit. Wear comfortable walking shoes, and bring warm items like a hat, gloves, warm socks, and an insulated jacket in late fall through mid-spring.
Visitors consistently rave about the exceptional knowledge and passion of the guides here. Names like Andy, Jim, Vince, Marsha, and Darci come up repeatedly, with reviewers impressed by their expertise in astronomy and ability to make complex topics accessible. The overnight and nighttime observation programs are the real highlights, offering intimate experiences with dedicated telescopes and patient instruction. Groups are kept small, which means plenty of time for questions and personalized attention throughout the evening. It's important to set realistic expectations about what you'll see through the telescopes. Several visitors emphasize that viewing celestial objects through an eyepiece looks very different from those colorful internet photos. You'll see smudges, dark areas, and stars rather than vibrant nebulae, since long-exposure camera techniques create those dramatic images. That said, people who understand this still find the experience incredibly worthwhile. The location itself is stunning, with unobstructed views of the Milky Way when conditions are right. Bring warm layers since temperatures drop significantly and you'll be sitting still for extended periods. Day tours exploring the solar telescope and various observatory facilities also receive excellent feedback for those interested in the facility's history and operations.
I attended the night "hiking" tour in late March. Our guide Jim was great: knowledgeable and enthusiastic. We got a special "treat" of observing the sunset from the (decommissioned) solar observatory. The moon was at zenith and although first quarter, it was still quite bright, so some of the fainter stars were washed out. But the sky was still spectacular! The walk was on paved roads with a short segment on gravel under the impressive solar observatory. The drive up/down the mountain was fun -- the road was well maintained and not at all scary. All in all, well worth the drive from Tucson!
