Observatory Museum
Some of the most important astronomical discoveries in history have been made at Lowell Observatory. Established in 1894, it is one the oldest observatories in the United States. Among other instruments, it is the home of the original, 19th-century Clark telescope and the famous astrograph used for discovering Pluto in 1930. During the day, the solar telescope allows you to take a close look at the sun, while at night you can view the stars, the moon, and the planets. Some programs might not be available at the time of your visit, due to weather conditions. The observatory is located at an altitude of 2,194 m (7,200 ft) and the sun can be very bright during the daytime while nights can be pretty cold, so don’t forget to bring sunscreen and dress in layered clothes.

  • Lowell is a fantastic observatory! The staff is extremely kind, professional, and knowledgeable. They were happily willing to answer my young children's questions, never showing any impatience. My chi...  more »
  • Great value - do both a day and night visit on one ticket and you get the best of both worlds - tours and solar experiences by day, stargazing and telescopes by night. It's also a beautiful location, ...  more »
  • Our mistake was expecting a modern working observatory. This is more of a walk back into history where Lowell and associates first explored Mars and ultimately discovered Pluto. A bit interesting, but...  more »

  • Great night trip. The stars in the sky were brilliant the views up on the mountain were amazing. We got to see the double Gemini stars orbiting. Unfortunately the moon didn't rise until 10pm and It was windy so they didn't open the big telescope. It was chilly at night in april so dress appropriately. The property grounds were amazing. We loved the gift shop too. The overall price value a little high at 20 per person we were lucky to have a coupon which helped.
  • Good place to visit. Good information and interesting facts. Out time there was short - would like to go back and spend more time there. We took 80 some kids there so a lot of our time was spent keeping track of everyone
  • Amazing place for the family or a date night. The staff is so friendly and great at explaining what you are looking at. The views are literally out of this world and its perched on top of a hill overlooking Flagstaff so while you wait for the telescopes on busy nights you can enjoy the city view. Wear comfy shoes as there is a little bit of walking but mostly waiting in line.
  • Great staff. Really passionate and helpful. Just arrive early, especially at night, if you want to use their telescopes. Sometimes there are a lot of people.
  • The evening solar system show was amazing. It was incredibly informative and interesting. Unfortunately, it was pretty cloudy so the telescope viewing was limited, but overall, the evening experience was wonderful. I was really disappointed with the day staff however. They were not very informed or professional. But this really was an amazing experience that I would highly recommend.
