Walker Creek Ranch is home to the Marin County Outdoor School and Conference Center. Owned and operated by the Marin County Office of Education we are located fifteen miles west of Petaluma. Our 1700 acre site includes forest, chaparral, grassland, and riparian ecosystems. These natural areas serve as an ideal setting for our residential outdoor education program, and for conference, wedding and retreat groups. Our site also hosts 20 miles of hiking trails, a four acre pond, an organic garden, and a low-ropes challenge course.
