About Helen Putnam Park

Helen Putnam Regional Park white clouds Helen Putnam Regional Park is just two miles from downtown Petaluma, on bucolic Chileno Valley Road. Its 216 acres includes 6 miles of trails that cross grassy hillsides and weave through groves of heritage oaks. Ridge-top trails provide panoramic views of the city to the east and the Sonoma-Marin countryside to the west. (Get inspired by this photo slideshow.)

The looped trail system lets hikers create walks of varying length and difficulty, making Helen Putnam a great choice for beginning hikers looking for a bit of a challenge. Trails are open to cyclists and horseback riders as well. (PDF fileDownload the trail map.) Other features include a large fishing pond, picnic area, and playground.

Like many other regional parks, the property used to be a ranch before it was purchased by the county in 1978 and opened as a park in 1983. The park is named after Helen Putnam, a former Sonoma County supervisor and Petaluma’s first female mayor.
