Coming Events

(Observatory is open to the public
ONLY for scheduled events).

Due to the recent fire, RFO is closed
through the end of 2017.

Although the observatory itself survived the fire, it will take some time before the park is ready to receive visitors. Please watch this space, and the RFO Facebook page, for updates as we move towards announcing a date when RFO will reopen.

For those of you that have upcoming Private Events, RFO will be contacting you with options. For those of you that have purchased tickets to individual upcoming events, you will be receiving refunds if they are canceled.

We are deeply grateful for the community's support during this crisis. Please know that the RFO family of 100+ volunteers wish all of you the very best, and we look forward to showing the stars again soon!

Sugarloaf Ridge
State Park

"Team Sugarloaf" operates Sugarloaf Ridge,
including the campground. Five nonprofit organizations formed a unique partnership that has worked tirelessly to keep our park open.  

Partners are: Sonoma Ecology Center; United Camps, Conferences and Retreats; Valley of the Moon Natural History Association; Sonoma County Trails Council; and Valley of the Moon Observatory Association.  

With expertise in campground operations, ecological restoration, astronomy, trails management, and volunteer recruiting and training, Team Sugarloaf is creating new opportunities for Sugarloaf Ridge and its visitors.  Visit sugarloafpark.org for more information.
