North River Wildlife Sanctuary, named for the state-designated Scenic River that winds along its northern boundary, serves as the base for South Shore Sanctuaries (which includes Daniel Webster and North Hill Marsh). 

The sanctuary's fields, oak forest, and salt marsh attract a wide variety of birds and seals are often visible from the riverside platform. Programs and summer camp take place in and around the historic building.
