Helen Putnam Expansion Project

Construction of a new trail in the park will begin the week of June 17 through August 30, 2019. The trail under construction starts at the intersection of the Pomo and Filaree trails and winds down to Windsor Drive. There may be temporary trail closures to Pomo Trail through the length of the project. For your safety, please follow any closure notices posted at the park. For project details

Helen Putnam Regional Park is a compact wilderness park southwest of Petaluma. Its 6 miles of trails cross grassy hillsides and weave through oak woodlands. Ridge-top trails provide panoramic views of the city and the southern Sonoma County countryside.

A fishing pond contains bluegill and other fish. An accessible playground, picnic area and gazebo are located near the parking lot.


Helen Putnam Park's looped trail system lets hikers create walks of varying length and difficulty, making the park a great choice for beginning hikers looking for a bit of a challenge. Trails are also open to cyclists and horseback riders.
