Visitors inside the Clark Telescope dome. Tom Alexander.


PROGRAMMING ALERT: The Clark Telescope is closed for renovation through mid-2015. Daytime Mars Tours will still go inside the dome when possible. In the evening, we will use the recently renovated 16-inch McAllister Telescope as our primary telescope for public viewing.

Peer through telescopes at night or visit the instrument that helped Clyde Tombaugh discover Pluto. Tour our facility with friendly, knowledgeable guides. Experience the Universe though widescreen multimedia shows, exhibits, live presentations, and SlipherVision, our new immersive space theater

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 traveling exhibits such as Black Holes: Space Warps and Time Twists, on display from January 18 - May 4.

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. Please note that while people walk their dogs in the nearby forest and several employees who live on Mars Hill own dogs, only service dogs are allowed in the areas of campus open to public visitation. During the summer, certain buildings and facilities may be closed during sessions of our Kids Camp.
