St Bathans, formerly named Dunstan Creek, is a former gold and coal mining town in Central Otago, New Zealand. The settlement was a centre of the Otago gold rush, but mining has since long ceased. It is now largely a holiday retreat due to the preservation of many of its historic buildings. St Bathans is well known for Blue Lake, a small man-made lake created by gold-sluicing that transformed the 120-metre high Kildare Hill into a 168-metre deep pit.
