Hamptonburgh is a wider area, but the main center of Hamptonburgh is Campbell Hall. Campbell Hall is home to America's first butter factory. It is also the location of the Otterkill Fire Department and the Campbell Hall post office. Its economy is derived from a number of sources: The General Store, Campbell Hall Salvage, American Fence, a Service Station, the Bull's Head Inn, and a number of horse and dairy farms. Campbell Hall also is home to Orange County AHRC, the Otterkill Golf and Country Club, and a Metro-North train station.
