Shollenberger Park Professional Review and Guide
"Shollenberger Park is part of the Petaluma wetlands complex, 500 acres of tidal and freshwater marshes along the banks of the Petaluma River in southern Petaluma. The river is actually a 14-mile tidal slough that stretches from Petaluma to San Pablo Bay. The 240-acre city park, created in 1995, was the site for materials dredged from the bottom of the shallow Petaluma River, allowing river navigation. A circular two-mile path loops around the dredge ponds, overlooking the preserved wildlife sanctuary, the wetlands, tidal marshes, and open fields. It is prime bird habitat for shorebirds and migrating waterfowl. The trail is popular for dog walking, jogging, bird watching, wildlife photography, and nature study, with sweeping vistas of southern Sonoma County and northern Marin County. Along the trail loop are several informative panels that describe the wetland’s ecology and history. Trail brochures are available at the trailhead. From the loop, a trail connects to the west to Alman Marsh (Hike 117) and to the northeast to the ponds at the water recycling facility along Ellis Creek."
