Great Brook Farm State Park [MA]
The 1,000-acre Great Brook Farm State Park preserves long-standing agricultural, Native American, and milling histories. Cellar pits mark the site of a 17th-century English mill community, portions of the grounds have been considered sacred to local Native American groups, and modern farming continues an on site Holstein dairy tradition which began prior to 1950.
The park offers dairy tours, more than 20 miles of trails, and outdoor activities. Dairy tours are offered May through October.
