Location
Castle Hill Basin is located in the Canterbury high country at an altitude of 700m approximately 90km northwest of Christchurch. It lies between the Torlesse and Craigieburn mountain ranges and is characterised by its distinctive limestone rock formations. These limestone rock formations are the water eroded remnants of limestone formed during the Oligocene age 30-40 million years ago when much of present day New Zealand was covered by the sea.

Kura Tawhiti
The area is of special cultural, spiritual and historical significance to Ngai Tahu who named it Kura Tawhiti(treasure from afar). Hidden amongst the limestone outcrops of Castle Hill are traces of 500-year old charcoal drawings traditionally said to have been left by the Waitaha, the first people to travel through this area. In 1998 the Kura Tawhiti Conservation Area was designated as Topuni to ensure that the values Ngai Tahu place on this area are recognised, acknowledged and respected.

IMPORTANT
To respect the special conservation and Topuni status of Kura Tawhiti, bikes, dogs and drones are NOT allowed in the Kura Tawhiti Reserve area

Castle Hill Village is the only settlement of any significant size in the Castle Hill area.
