Modern stonework borders the 1/2 mile path to the inner Dún Aonghasa walls, keeping tourists off delicate plants, maintaining the integrity of this ancient site.
The view north, northwest over the walled path to Dun Aonghasa (Dun Aengus) looking across karst landscape, walled fields, farms, the North Atlantic Ocean, coast of Connemara and the 12 Bens (12 Pins) mountains. Aran Islands, County Galway, Ireland.
