This 35ha/74acre park is a showcase of horticulture in the Orleans region. It contains a large variety of plants, most notably an exceptional iris collection. Other delights for the eyes include the mirror which commands a stunning perspective of the castle and the delicate "Louis XIII embroidery" that decorates the lawn. The bubbling source of the Loiret can also be observed from there. For children: alpacas, flamingos, and little waders along with a butterfly house.
