That depends on the group! Some can stay from open to close to experience everything the observatory has to offer, others will stop by for an hour or so to take a tour or see the grounds. According to our Google profile, the average stay time is about 2 hours.

Reservations are not required for the purchase of general admission tickets, but reservations are required for our Premium Access experience. 

We typically open the telescopes around sunset, which varies depending on the time of year. It can be as early as 4:30pm in the winter, or as late as 8pm in the summer.

Clouds are the most common reason for telescopes not to be operating. If the cloud coverage isn’t full, our educators will try their best to spy visible objects through gaps in the clouds.

If our telescopes aren’t open due to inclement weather or operational issues, guests are still welcome to tour the telescope facilities and learn their history through our educators. We also offer educational talks and a variety of walk-through exhibits, like the Universe Walk and the Putnam Collection Center.

The Pluto Discovery Telescope is an astrograph, a special kind of telescope that has no eyepiece, but instead a mechanism for taking pictures. The telescope is no longer in operation, but guests can visit the facility to view the telescope and learn about the discovery of Pluto.

Nope! In terms of astronomy, an observatory is a facility that houses equipment used to study the cosmos, like telescopes. A planetarium, on the other hand, is a theatre in which star images are projected onto a screen. Lowell Observatory is an independent, non-profit research institution. Some parts of our campus are closed to the public, but we have several telescopes and exhibits that visitors can check out!

Currently, we have snacks and pay-and-take style meals available for purchase in our Starry Skies Shop. Guests are welcome to bring their own food and drink with them on campus as well. We will have an on-campus cafe in our brand new Astronomy Discovery Center, set to open in 2024!

We have a main visitor parking lot, as well as an overflow lot. It can accommodate RVs, but parking is first-come, first-served and may not be able to accommodate larger vehicles on very busy nights.

We are located in Flagstaff, Arizona, just one mile west of the historic downtown area. The observatory sits atop Mars Hill, a mesa that rises several hundred feet above the historic town.

Flash photography is permitted during the day, but we ask that guests avoid the use of any type of white light (including camera flash, flashlights, and phone screens) at night to avoid causing glares in the telescopes and impairing other visitors’ night vision.

Yes! Since we currently have few dining options on campus, you are more than welcome to bring your own food and beverages with you on campus. We have tables available inside the Steele Visitor Center and picnic tables located outside in the Pickard Grove.
