Explore the Universe at Lowell Observatory

At Lowell Observatory, History and Science come together! Guided tours of the historic campus give visitors a chance to explore the famous path Clyde Tombaugh took the night he discovered Pluto. Experience the cosmos though widescreen multimedia shows, exhibits, and live presentations. Daily safe viewing of the Sun and nightly stargazing are offered during favorable weather.

A family friendly venue, Lowell Observatory allows everyone to explore the history of the universe, as well as modern science research.

For general questions about our day and evening programs, call the Visitor Center at (928) 774-3358 during business hours.


Overnight camping and overnight RV parking is not permitted.

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.


Weather conditions play an important role in the activities and telescope viewing opportunities we are able to provide. We encourage checking the weather forecast as close to your visit time as possible.
