Welcome To The Sonoma/Petaluma State Historic Parks Association.
The Sonoma/Petaluma State Historic Parks Association is a non-profit organization and a cooperating association of the California State Parks. We serve and support Sonoma State Historic Park and the Petaluma Adobe State Historic Park.
Our mission is to further the interpretive and educational activity and experience for visitors to these State Parks. We support the docent program, lecture and concert series, and community events.
Additionally, we help preserve these wonderful parks by providing seed money for critical restoration projects.
