Today it is an historical site and museum. In earlier times, it was a working sugar cane plantation, then after the turn of the century it would become a cattle ranch. Today's Oak Alley Plantation is two entities: the non-profit Oak Alley Foundation which owns and manages the historic Big House and Alley of Oaks, and the Oak Alley Plantation Restaurant & Inn which operates a restaurant, gift shop, and overnight cottages on the grounds. The property is also leased out as a working sugar cane plantation today.
Today, Oak Alley Plantation is a historical museum dedicated to telling the story of this historic property, run by the Oak Alley Foundation. Surrounding the historic grounds, but once considered part of the plantation, are fields of sugar cane farmed by local farmers not affiliated with the Foundation. You can learn on their website.
