Outline Geosite Description
Coastal cliffs and fields, with a blowhole included.
Geological System/Age and Primary Rock Type The rocks are of Ordovician age, but the blowhole is a Holocene feature eroded by the sea.
Main Geological or Geomorphological Interest
A classic blowhole is displayed on the clifftop on the eastern side of Kilmurrin Cove. The sea has eroded a sea cave inland until there has been a collapse to surface at the inner, landward end. This has been progressively enlarged by tides and now a steep sided depression is seen with the sea entering and leaving by a short cave, or natural tunnel.
Alone, this is of County Geological Site importance but is part of a complex of sites along the Copper Coast, which collectively are of national importance, and which are already part of a proposed NHA (Ballyvoyle Head to Tramore No 1693).
Access and Safety
Car parking is possible at Kilmurrin Cove.
