Come run the Inaugural Mt. Wilson Observatory 5K! A run around the mountaintop, starting at the 100-inch telescope and ending at the top of the Mount Wilson Trail. Have fun and help us raise funds to improve the Observatory grounds. Afterwards, there will be awards, food and live music. All proceeds from this fundraiser will be used for these specific projects:

  • Adding benches and picnic tables throughout the observatory grounds
  • Creating lookout points in various locations
  • Building a public restroom near the Sturtevant trail entrance which lies between the 60-inch and 100-inch telescopes.

As a non-profit organization, the observatory relies solely on funding from the Cosmic Café, night telescope viewing sessions, public tours, a few small grants and the generosity of public donations.
We sincerely appreciate your support and are grateful for all those who recognize that Mt. Wilson Observatory is a place of great history and beauty.

DON’T WANT TO RUN A 5K BUT WOULD STILL LIKE TO SUPPORT?  YOU CAN DONATE BELOW AND ALL PROCEEDS FROM THIS FUNDRAISER SITE WILL GO DIRECTLY TOWARDS THE PROJECTS LISTED ABOVE. THANK YOU ONCE AGAIN FOR YOUR SUPPORT!

Since 1904, the Mt. Wilson Observatory has kept its grounds open for the public to freely walk among the telescopes where some of the most significant discoveries in astronomy have been made.  Over the past 100 + years, the public has seen the mountaintop change considerably, from rising telescope domes, hotels, a petting zoo, a restaurant, cafes, broadcast towers and more.  Throughout it all, one thing has remained constant: the public continues to have free access to visit the grounds of Mt. Wilson Observatory.
