Main image

Valentia Island lies off the southwest coast of County Kerry, Ireland, and is one of the country’s most westerly inhabited islands. It is historically important as one end of the first successful transatlantic telegraph cable completed in 1866.

The island offers coastal cliffs, headlands and sheltered bays with viewpoints over the Wild Atlantic and toward the Skellig Islands. Visitors use the island for walking, heritage interpretation focused on the transatlantic cable, and local village services concentrated in Knightstown.

The island’s maritime and geological heritage has been the subject of conservation and interpretation; bedrock exposures on the island are part of regional geological interest. Valentia is connected to the mainland by a short bridge and lies close to the Iveragh Peninsula and mainland towns such as Cahersiveen.

Valentia Island is situated off the Iveragh Peninsula in County Kerry, accessible by road across a small bridge from Portmagee and by ferry services in the region. It occupies a coastal position facing the Atlantic and the Skelligs.

  • Transatlantic cable landing: One end of the first successful transatlantic telegraph cable was landed here in 1866, and interpretive displays at the island explain that history.
  • Geology and views: The island forms part of a designated geopark with rock exposures of Devonian age; coastal cliffs and headlands provide views of the Skellig Islands and Atlantic sea lanes.

What to See #

  • Cromwell Point (cable landing): Cromwell Point and the cable station - the western tip of the island that served as a landing point for the 1866 transatlantic telegraph cable and hosts interpretation material about the cable connection.
  • Knightstown: Knightstown - the island's principal village and service centre with ferry and road connections, local shops and visitor facilities.
  • Valentia Lighthouse and headlands: Valentia Lighthouse and viewing terraces - coastal viewpoints that look out toward the Skellig Islands and the Atlantic seascape, popular for sunsets and marine views.
