Lowell Observatory, Flagstaff
(4.4/5 based on 1,200+ reviews on the web)
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.

  • My wife loves astronomy and so, when traveling through Flagstaff we had to stop. We arrived early in the afternoon and found several interesting tours. The hard part was sitting around until dark so w...  more »
  • Something different to see. This Observatory you can visit day or night. I recommend making it with a tour to appreciate everything what there is exposed. They say that here was discovered Pluto for the first time

  • Surprised at how much I enjoyed the tour and information given. Tour guide was informative and a pleasure to listen to.

  • It's a really great and neat place for those even vaguely interested in astronomy. The tour guides are very knowledgeable. My daughter just turned 11 and we came up from Phoenix to go here for her birthday. My only issue with it is they are limited in staff so sometimes it can be hard to find someone to answer your questions adequately. Also, sometimes the tours run long and then you miss the start of the next one. Or if you can't/don't want to be there all day, you have to choose between seeing certain things/tours. Really neat place, a little steep in price for what is offered, though. They do offer veteran's discount though, we appreciated that.
  • This was such a cool place to come to . We leaned so much we spent the whole day plus part the early evening . We go to the sun throw the telescope also stars and galaxies . They awesome staff that were so friendly and you can ask them about anything. We were during the Halloween weekend so they had there own hunting tour which awesome . If want to go place and learn about space this it awesome place to visit and spend the day for all ages ..
  • Awesome observatory. They let you look into their telescopes and give you basic instruction on what you are looking at (if the line isn't too big). There are classes and a cool gift shop. Lots of rude tourists willing to push you around without provocation. Get the opportunity to study rudeness from several cultures!
  • Amazing, found it by fluke when I had a spare day and such a wealth of information here. Great for 3 hours or so and they have done lots with it, a real gem. If you have any interest in this kind of thing, even if you don't, definitely worth a visit! Loved it, the story or finding Pluto is just so good.
  • One needs to bear in mind that this place is first and foremost a research facility. Don't expect awesome exhibits or really great tour guides. In fact, I wouldn't recommend this for families with small children. The interactive exhibit in the visitor center is big on flashy touch screens but the content is best suited for older kids. That being said if you are a sky nerd then you will probably love this place and the staff really knows there stuff! The stargazing events are really cool if you like big telescopes and talking details.
