Sonoma Ecology Center focuses on projects in Sonoma Valley, including the communities of Sonoma, Glen Ellen, Kenwood, Boyes Hot Springs, and Eldridge. We collaborate on projects throughout Sonoma County and beyond.

Physical Address & Directions

We are located on the campus of the former Sonoma Developmental Center (SDC), in Eldridge near Glen Ellen. To find us, proceed to the main intersection of the former SDC at 15000 Arnold Drive. Turn east, away from the historic brick building, onto Harney Drive. Continue across a narrow bridge. At the far side of the bridge, turn left into our small driveway.

Please note that typing our address into most navigation maps is not effective (entering “Sonoma Ecology Center” into Google Maps does usually work). Our coordinates are available here: VIEW MAP.
