01
Best overall pick
Helen Putnam Regional Park
Southwest Petaluma Hills • Rolling Hill Regional Park With Loop Options • Local Favorite For Classic Petaluma Scenery
Short but satisfying hill loops with big views over Petaluma and easy access from town.
Tucked into the low hills just southwest of town, Helen Putnam Regional Park packs roughly six miles of interlinked trails into a compact footprint, making it easy to tailor a quick loop or a longer wander[2]. Expect steady but manageable climbs through open grassland, pockets of oaks, and ridge sections that look back over the city and out toward Sonoma Mountain. It is an ideal first stop if you want a “this is Petaluma” hike without committing your whole day.
02
Best easy wetland walk
Shollenberger Park
Petaluma River Wetlands, East Side • Level Gravel Loop Around Tidal Ponds • Best For Birding And Relaxed Strolls
A flat loop skirting the Petaluma River marshes, popular with walkers, birders, and families.
Shollenberger Park offers one of the easiest ways to get outside in Petaluma: a mostly level loop that traces dikes and levees around restored wetlands along the river[6]. The broad path works well for strollers and casual walkers, while frequent benches and viewing platforms make it easy to linger over pelicans, shorebirds, and seasonal waterfowl. Go early or near sunset for cooler temperatures, softer light, and better wildlife activity.
03
Best short nature escape
Ellis Creek Trail
Southeast Petaluma Wetlands • Mixed Gravel And Dirt Paths Through Marsh And Ponds • Best For Quiet, Close-To-Town Wandering
A mellow network of paths connecting ponds, wetlands, and marsh edges just beyond Shollenberger.
Linked to Shollenberger Park but a little quieter, the Ellis Creek area weaves around treatment ponds, cattail stands, and open marsh, with spur paths that feel surprisingly tucked away given how close you are to town[6]. The mostly flat route is great when you want fresh air and birdlife without driving out into the hills. It pairs nicely with a lap at Shollenberger if you are looking to stretch a short outing into a full morning along the river corridor.
04
Best wide-open ramble
Tolay Lake Regional Park
East Of Petaluma Off Lakeville Highway • Expansive Ranchland Park With Longer Routes • Best For Big-Sky Vistas And Longer Hikes
Miles of ranch roads and singletrack roll over open grasslands with views toward San Pablo Bay.
Set in former ranchland southeast of Petaluma, Tolay Lake Regional Park offers over 11 miles of trails that climb gently through broad valleys and up to airy ridgelines with long views[1]. The hiking has a spacious, big‑sky feel, with grazing cattle, seasonal wildflowers, and very little shade, so it is smart to bring sun protection and extra water. Choose a shorter out‑and‑back from the main lot or commit to a longer loop that fully explores the upper ridges.
05
Best half-day challenge
North Sonoma Mountain Regional Park & Open Space Preserve
East Of Petaluma Near Sonoma Mountain • Forest And Ridge Trail Into Higher Country • Best For Stronger Hikers And Big Views
A sustained climb up the North Sonoma Mountain Ridge Trail into cooler forests and sweeping overlooks.
A short drive from Petaluma, North Sonoma Mountain Regional Park delivers a more demanding outing, with the Ridge Trail steadily gaining elevation through mixed forest and out onto open slopes[4]. The payoff is a series of broad viewpoints across Sonoma Valley, glimpses back toward Petaluma, and a sense of stepping into higher country without driving to the Sierra. Plan on a few hours, carry plenty of water, and expect a real workout on the return climb.
