Day or night, adults and kids alike can explore the Universe at Lowell Observatory.

Peer through the telescope that Percival Lowell used to sketch Mars or visit the telescope that helped Clyde Tombaugh discover Pluto. Tour our facility with friendly, knowledgeable guides. Experience the Universe though widescreen multimedia shows, exhibits, live presentations, and our 3D portable planetarium.

Your visit here begins in the 6,500-square-foot Steele Visitor Center, where our team will get you started on your journey of exploration. In addition to our tours and multimedia shows, we offer the Honeywell Children's Exhibit for kids. Best of all, in the evening you can enjoy Flagstaff's beautiful dark skies and spectacular views through the Alvan Clark Telescope.

Come up and see us on Mars Hill, 1 mile west of downtown Flagstaff, Arizona. And welcome to Lowell Observatory.

IMPORTANT REMINDERS: Lowell is located at 7200'. You will want to pace yourself if you're not accustomed to the high elevation. Avoid becoming dehydrated by drinking plenty of water. Dress in layers; evenings can be cold, even in the summer. In the daytime, wear sunscreen to protect against sunburn.
