Natural History

Join National Park staff at Saugus Iron Works National Historic Site for a 30-minute tour of The Iron Works House. Saugus Iron Works National Historic Site preserves and interprets the first sustained, integrated iron works in British Colonial America, which operated on the Saugus River from 1646 to 1670. Explore the place where European iron makers brought their special skills to a young Massachusetts colony. Saugus Iron Works is a twelve-acre National Historic Site that includes working waterwheels, forges, mills, a historic 17th century home, and a lush river basin.

A CraneOutdoors Family Winter Wildlife Walk will take you on a stroll through the Crane Beach dunes while learning about the plants and animals that call this special place home.

They offer one of the most accessible dune landscapes in New England and trails that provide a firsthand look into the delicate and ever-changing dune habitat. This includes numerous lookouts offering stunning views of Choate Island and the varied ecosystems of Castle Neck, including Pitch Pine forests and naturally occurring cranberry bogs.
