Bunmahon Head

Outline Site Description
The site comprises a rocky headland and Trawnamoe beach to the west.

Geological System/Age and Primary Rock Type
The rocks of Bunmahon headland are Devonian age sandstones and conglomerates. The adjacent rocks in the bay to the west are Ordovician volcanic and sedimentary rocks.

Main Geological or Geomorphological Interest
Mining heritage is highly visible in the bay with small adits cut into the rocks. The volcanic lavas at the western end of the Trawnamoe beach show very interesting features, which are called peperitic intrusion. When andesite lava was being injected into wet sediments, it broke up into rounded blobs and was extensively altered by hot fluids.

The headland of Bunmahon Head is composed of Devonian age red sandstones and conglomerates. These are tilted to vertical and form impressive cliffs. A fault runs to the west of the headland separating them from the Ordovician rocks.

Site Importance
The site is part of the 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).

Management/promotion issues
There is reasonable access via a cliff top track from Bunmahon, and a path onto the headland or down into the bay via a grassy slope. The remote feel of this place is perhaps best left untouched by explanatory panels, but the clifftop viewpoint into the bay or the car park at the end of the rough track would be the place to install any such interpretation or explanation.


About Copper Coast Geopark

The Copper Coast Geopark is in Co. Waterford, Ireland and is an outdoor museum of geological records; it stretches along the coast from Kilfarassy Beach, near Fenor in the east to Ballyvoile Beach near Stradbally to the west. Volcanoes, oceans, deserts and ice sheets all combined to create the rocks which provide the physical foundation of the natural and cultural landscapes of the area. Follow the self-guided "Copper Coast" trail and walking cards available from the The Copper Coast Geopark Centre in Bunmahon.
