Kasteel Twickel (twickel Castle) is well-known for its gardens and park. The gardens have been developed by the various generations and give a good impression of the history since the Renaissance.

The formal garden offers clipped figures of the taxus and buxus trees. The ornamental garden garden in Victorian style has been designed by the last baroness. The surrounding park - with its large water gardens - are developed in English landscape style during the 18th and 19th century. The park has also a wildlife sanctuary with a pack of fallow deer.

The orangery was built in the first half of the 19th century. It serves as a winter residence for the (sub)tropical plants, such as the 300 year old orange trees.
