Billings Farm and the National Park Service have teamed up to manage this newer park, the first and only national park focused on the history of conservation. It's more or less right across the street from the Billings Farm , and is closely related. Here you'll learn more about the life of George Perkins Marsh, the author of Man and Nature (1864), one of the first and most influential books in the history of the environmental movement. You'll also learn more about how Woodstock native/rail tycoon Frederick Billings, who read Man and Nature, eventually returned and purchased Marsh's boyhood farm, putting into practice many of the principles of stewardship Marsh espoused. The property was later purchased by Mary and Laurance Rockefeller, who in 1982 established the nonprofit farm; a decade later, they donated more than 500 acres of forest land and their elaborate Victorian mansion, filled with exceptional 19th-century landscape art, to the Park Service. Visitors can tour the mansion, walk the graceful carriage roads surrounding Mount Tom, and view one of the oldest professionally managed woodlands in the nation. Mansion tours accommodate only 12 people at a time, so advance reservations are highly recommended; check in at the visitor center, located inside a carriage barn, to reserve one (or call ahead).
