Inset: location within Pembrokeshire
Dinas Island (Welsh: Ynys Dinas) is a peninsula, partially detached from the mainland, in the community of Dinas Cross between Fishguard and Newport, Pembrokeshire, in southwest Wales. A triangulation point shows 466 feet (142 m) above sea level at Pen-y-fan. Although Dinas Head is the northernmost part of the promontory where the cliffs meet the sea, the name is sometimes loosely used to refer to this highest point.[1] Dinas Island is contained within the Pembrokeshire Coast National Park and the headland is under the care of the National Trust.[2]
