St David's Head

St David's Head (Welsh: Penmaen Dewi) is a headland in the Pembrokeshire Coast National Park, southwest Wales, which marks the divide between the Irish Sea and the Celtic Sea. It is noted for its wildflowers and wildlife, and for the remains of ancient human settlement. The headland and its immediate hinterland are owned by the National Trust, and are accessible to the public by foot via the Pembrokeshire Coast Path.

The westernmost point of mainland Wales, Pen Dal-aderyn, is located just to the south of St David's Head.
