01
Best close-to-town escape
Helen Putnam Regional Park
Southwest Petaluma Hills • Compact Hilltop Regional Park • Best For Quick, View-Filled Loops
A small but surprisingly varied network of hill trails with big views over Petaluma and out toward the Sonoma County countryside.
From the Chileno Valley Road entrance, you can stitch together short loops that climb quickly to open ridges with classic rolling-hill vistas. The trails mix grassy slopes and pockets of oak woodland, making it an easy place to get a real hike in under two hours. It’s a go-to for locals who want elevation gain, scenery, and an easy drive from Penngrove.
02
Relaxed meadow-and-oak rambles
Crane Creek Regional Park
Between Penngrove And Rohnert Park • Grassy Creekside Park With Oak Woodlands • Best For Laid-Back Weekend Wanders
Gentle loops through open meadows and along a seasonal creek make this a low-key spot to stretch your legs close to town.
Crane Creek’s rolling pastures and scattered oaks feel more like a quiet ranch than a formal park, which is exactly the appeal. The trails are mostly mellow, with a few short climbs that reward you with views toward Sonoma Mountain and the Rohnert Park plain. It’s an easy choice when you want fresh air, dog-friendly paths, and a less crowded alternative to the bigger parks.
03
Best ridge-line adventure
Sonoma Mountain Regional Park & Open Space Preserve
Foothills East Of Penngrove • Forest-And-Meadow Ridge Park • Best For Longer, Workout-Style Hikes
Climbing trails wind through shaded forest to open ridges with long views toward the Sonoma Valley and beyond.
The main route here steadily gains elevation, trading lower oak woodlands for fir and laurel as you climb toward the Sonoma Mountain crest. Switchbacks keep the grade reasonable, but it still feels like a real trek, especially if you connect multiple segments into a longer out-and-back. On clear days, the payoff is wide-angle views and a real sense of being up above the valleys that ring Penngrove.
04
Classic all-day destination
Trione-Annadel State Park
Eastern Santa Rosa • Expansive State Park With Lake And Mixed-Use Trails • Best For Varied, All-Day Exploring
A big, trail-rich park where you can choose everything from short forest loops to half-day circuits around a quiet lake.
Annadel’s network of paths lets you build the day you want, whether that’s a shady hike to Lake Ilsanjo or a longer loop that strings together multiple ridges. Expect rocky tread in places, sharing some multi-use routes with mountain bikers, and a mix of open chaparral and cool forest. It’s the spot locals pick when they want to log serious miles without driving deep into the mountains.
05
Best big-view workout
Taylor Mountain Regional Park & Open Space Preserve
Southeast Santa Rosa Slopes • Open-Slope Ranchland-Style Park • Best For Sunset Climbs And Fitness Hikes
Steady climbs on ranch roads and singletrack lead to sweeping views across Santa Rosa, the Laguna, and out toward coastal hills.
The lower trails start out easy, weaving past grazing land and seasonal wildflowers before tilting upward toward the summit area. As you climb, the landscape opens wide, with very little tree cover, so timing your visit for cooler hours or sunset pays off in comfort and color. Hikers from Penngrove come here when they want a straightforward, heart-pumping ascent with big-sky scenery as the reward.
