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 at these State Parks within our communities of Petaluma and Sonoma.

Additionally, we help preserve and protect these wonderful parks for our future generations to enjoy!
