North River Wildlife Sanctuary

North River Wildlife Sanctuary is a protected natural area in Marshfield featuring oak forests, salt marshes, and open fields spread across rolling terrain. Multiple walking paths wind through these habitats, offering access to riverside views and opportunities to observe the landscape's different plant and animal communities.

From 1690 to 1870, this area was a major center for shipbuilding, with local timber harvested to construct sailing vessels for maritime trade. The land later transitioned to conservation status, preserving its woodland heritage as a natural sanctuary.

The Mass Audubon Society manages educational programs at the nature center, teaching visitors about local ecosystems and environmental conservation methods.

The sanctuary is open daily from sunrise to sunset with well-marked trails suitable for various fitness levels. Pathways are maintained and lead through different sections of the property, allowing visitors to explore at their own pace.

A specially designed accessible trail winds through wet maple forests with raised platforms that welcome visitors with different mobility needs. From these viewing points, harbor seals and water birds that inhabit the river can often be spotted.
