Ardenwood Historic Farm is located at 34600 Ardenwood Boulevard in Fremont, California. Although Ardenwood is open year round, the peak season for visiting the farm is during the summer (April 1 to November 15). During the winter, the Patterson House is closed and the farm offers fewer activities for visitors. Still, you will be able to stroll through the grounds and visit the various farm animals and peacocks that have made the farm their home.
