Castle Hill is a location and a high country station in New Zealand's South Island. It is located at an altitude of 700 metres, close to State Highway 73 between Springfield and Arthur's Pass. It is private property and located within the Kura Tawhiti Conservation Area.
The hill was so named because of the imposing array of limestone boulders in the area reminiscent of an old, run-down stone castle. The front of ChristChurch Cathedral in Christchurch was made from Castle Hill limestone. The station was established by the Porter brothers, and later owned by brothers John and Charles Enys. John Enys was a noted entomologist, and friend of novelist Samuel Butler.
