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 the fish 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 steep climb up Panorama Trail from the parking lot or a gentler approach via the paved Ridge Trail past the Fish Pond.
- Fillaree, Pomo, Savannah, and South Loop trails wind through dense oak woodlands and offer shade on hot summer days.
Equestrians, hikers, and bikers are welcome on all trails.
Restrooms and drinking fountain are available in the Chelino Valley Road parking lot.
