On top of Gormanston Hill on the Lyell Hwy, just before the final descent along hairpin bends into Queenstown, is a sealed side road leading to an utterly spectacular lookout over the geological wound of Iron Blow. This decommissioned open-cut mine, where Queenstown’s illustrious mining career began, is awesomely deep and is now filled with emerald water. You can get an eagle’s-eye view from the new ‘springboard’ walkway projecting out into thin air above the mine pit.
