Collection of World War I & II planes lovingly restored and captured in realistic settings. Part of the attraction is the association of Peter Jackson (of Lord of the Rings fame) and Weta Workshop with the display. His team has turned what could be just a collection of planes into a drama enjoyed by even those with little interest in aviation or military history. Worth it. Has a cafe.
See the formal gardens.
Beautiful landscaping. Don't miss the roses and camellias.
