Save our State Park and RFO

Sugarloaf Ridge State Park is under threat of closure. Help us keep the Park and the Observatory open!

RFO’s operator, Valley of the Moon Observatory Association, and its partners—including the Sonoma Ecology Center, United Camps Conferences and Retreats, Valley of the Moon Natural History Association, and Sonoma County Trails Council—are negotiating with the state to operate the park. Join us at: sonomaecologycenter.org and parksalliance.com

Tell your legislators that you do not
support the closure of our state parks.

SOSThe Parks Alliance for Sonoma County was created to address closures of State Parks in Sonoma County. 
Sign up to volunteer, receive updates and make donations that specifically support Sugarloaf Ridge State Park at sonomaecologycenter.org and parksalliance.com or by downloading the form on the Parks Alliance webpage and sending it in.

Thank you for supporting RFO!
