Stroll the grounds and gardens of Marsh — Billings – Rockefeller National Historic Park, preserved by the National Park Service. It is the site where Frederick Billings, a well-to-do lawyer and financier, established a revolutionary forest and dairy farm.

You can also take a guided tour of the Marsh-Billings House (George Perkins Marsh Boyhood Home), where Mr. Marsh, a conservationist, grew up as a child.

The park is located adjacent to Billings Farm, which offers interactive opportunities for kids to milk cows, churn butter and more.
