See What’s New at Helen Putnam Regional Park

Celebrate the improved Helen Putnam Regional Park! You're invited to visit this popular Petaluma regional park, take a self-guided tour of the recent improvements we've made, and acknowledge the funders and volunteers who made this work possible. 


Helen Putnam Regional Park lies just southwest of Petaluma in the rolling hills of the Chileno Valley and offers nearly 6 miles of trails across varied terrain.

  • The Ridge Trail has two parallel routes between the parking lot and Cattail Pond. One is paved, and one is dirt. 
  • Excellent views of Petaluma to the east and Sonoma County countryside to the west can be enjoyed from the Panorama Trail. The viewpoints can be reached via a climb up Arroyo Trail from the Chileno Valley Road parking lot or a gentler approach via the paved Ridge Trail past Cattail Pond.
  • Filaree, Pomo, Savannah, and South Loop trails wind through dense oak woodlands and offer shade on hot summer days.
  • West Wind Trail is a new trail linking the north side of the park to a new parking area on Windsor Drive. West Wind trail connects to Filaree and Pomo trails. 

Equestrians, hikers, and cyclists are welcome on all trails.


The park features accessible parking and path of travel. The paved Ridge Trail section does not meet standards for accessibility as it is too steep along most of the length – however it is feasible if using a powered mobility device.
