Why Lowell Observatory Is a Must-Visit
Lowell Observatory isn’t just another stop on your Arizona road trip—it’s a gateway to the stars. Founded in 1894 by Percival Lowell, this place has been unlocking the universe’s secrets for over a century. It’s where Pluto was discovered in 1930, where the expanding universe was first confirmed, and where Apollo astronauts trained for moon missions. Add to that Flagstaff’s status as the world’s first International Dark Sky City, and you’ve got a recipe for unforgettable stargazing. Whether you’re a science nerd or just someone who loves a good view, Lowell’s mix of history, science, and jaw-dropping celestial sights makes it a bucket-list destination. Who wouldn’t want to stand where history was made?
A Glimpse into Lowell’s Rich History
Picture this: it’s 1894, and Percival Lowell, a wealthy Bostonian with a passion for Mars, sets up shop on a hill in Flagstaff to chase his cosmic dreams. His observatory became a hub for groundbreaking discoveries, from V.M. Slipher’s evidence of an expanding universe to Clyde Tombaugh’s discovery of Pluto. Designated a National Historic Landmark in 1965 and named one of Time Magazine’s “World’s 100 Most Important Places” in 2011, Lowell’s legacy is as vast as the cosmos itself. Walking its campus feels like stepping into a time machine—can you imagine peering through the same telescope that spotted Pluto?
Getting to Lowell Observatory
Lowell Observatory sits just a mile west of downtown Flagstaff at 1400 W. Mars Hill Road, making it an easy jaunt from wherever you’re staying. If you’re driving, follow Santa Fe Avenue to the well-marked signs, and you’ll find free parking near the Steele Visitor Center. For those using public transit, Flagstaff’s Mountain Line buses stop nearby, or you can grab a rideshare from downtown. The observatory is open Wednesday through Monday from noon to 10 p.m. (11 p.m. in summer), so plan to arrive early for daytime tours or stay late for stargazing. Pro tip: Check the weather, as clear skies are key for the best experience. Ready to navigate your way to the stars?

Tips for an Out-of-This-World Visit
Planning your trip to Lowell Observatory? Here’s how to make it a stellar experience, from beating the crowds to staying comfortable at 7,200 feet elevation.
Timing Your Visit
For the best stargazing, visit on a clear, moonless night—winter is ideal for crisp skies, but summer offers longer hours (until 11 p.m.). General admission ($35 for adults, $20 for kids 5–17) covers all-day access to tours, exhibits, and stargazing. Arrive early for daytime tours, then return after dusk for telescope viewing. If you’re short on time, prioritize the evening programs for the full cosmic experience. Isn’t it worth staying late to see Saturn up close?
What to Bring
Flagstaff’s high elevation means cooler temps, especially at night, so pack a jacket or sweater. Comfortable shoes are a must for walking the campus, and a reusable water bottle keeps you hydrated. If you’re into photography, bring a camera for daytime shots of the historic domes or astrophotography gear for night sessions (check out their $79 astrophotography course!). A small flashlight with a red filter helps you navigate without ruining night vision. Ready to pack like an astronaut?

Lowell Observatory is wheelchair-accessible, with ramps and railings throughout the campus. The Giovale Open Deck Observatory and Astronomy Discovery Center are designed for all ages and abilities, so everyone can join the fun. If you’re visiting with young kids, note that some talks might be too advanced for toddlers, but the interactive exhibits keep them entertained. Bring snacks or grab a bite at the Planet X Cafe to refuel. Doesn’t it feel good to know everyone can enjoy the stars?
