Ross Island Copper Mines

Ross Island Copper Mines are a Bronze Age mining area on the wooded shore of Lough Leane, with rock cuts, flooded shafts and interpretation along Killarney’s Mining Trail. This is an outdoor stop, not an underground tour: you follow the path past former workings and boards. The 3 km Mining Trail starts and finishes at Ross Castle car park. It’s listed as easy and mostly flat; the mine loop is a section of that walk, reached after about 800 metres.

Start past the castle, then turn onto the narrow walking path. The car park, public toilets and a seasonal coffee shop are at Ross Castle, not out by the mine. Some woodland alternatives are rougher and uneven, and lower paths can flood in winter or after heavy rain.

Old shaft openings remain close to the route, including a flooded shaft known as the Blue Hole. Stay on the established path and keep children close; the workings aren’t places to enter or explore. The water and old cuts are the story here, but they’re also the reason to resist a closer look.

The loop passes a dam wall, shaft openings and interpretation boards before reaching a stony shore on Lough Leane. The Blue Hole is a flooded shaft with green-tinted water; across the lake, the view opens toward Torc and Mangerton. At the shore, include a strip of stones with the mountains across the water to keep the view tied to the mine walk. For a closer photo, frame the copper-stained rock cut beside the path.

The tools were simple by modern standards: miners used shovels made from cattle bone and hammers of stone cobbles. Researchers think they may also have used fire-setting, heating the rock with wood fires before breaking it with stone tools. That’s an inferred technique, but it gives the flooded cuts and broken rock a human scale.
