Create an itinerary including Lowell Observatory
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.

  • What a fantastic museum! I am not an astronomy buff, but with the cool history of the Lowell Observatory and the super accessible telescopes, I might become one. It is a little pricey, but the...

  • This is one of my favorite places on planet earth. I recommend going an hour before sunset and staying until they close at night. The Flagstaff sky is unreal and I could not stop staring into the sky full of stars. Such kind and smart people work there. The location is easy to get to, only a five minute drive from downtown. Plenty of parking but it does get full so beware! There are stairs and ramps for accessibility. The gift shop is awesome. I’m in love with this place and I want to come back during every season. You will learn so much and see so much amazing history. It’s amazing that you can step into the observatory that discovered Pluto! So worth it.
  • Wow! What an amazing experience to learn about astronomy and view the solar system through their incredible telescopes. We attended 3 of the programs throughout the day - all excellent, and led by knowledgeable staff who are passionate about their job. Staff were all friendly and helpful. What a treat that we were privileged to use the famous 32 foot Clark Refractor once it got dark. The outdoor viewing deck was awesome! We had so much fun learning, seeing, and exploring the grounds. Must do for any age!
