The 20-hectare park around the château was redesigned in the late 19th century by Henri Duchêne, the landscape architect more famous for his work at Vaux-le-Vicomte. Duchêne kept the English-style lawns and specimen trees added by an earlier owner and ran sweeping avenues through them down to the river.
Walking the park is free with the château ticket. The cedars and sequoias planted under Broglie are now massive, the meadow drops away dramatically toward the Loire, and on a clear day you can pick out the spires of Onzain on the opposite shore.
