The diminutive Pembrokeshire Coast National Park, a dramatic area of 225 square miles in southwest Wales, was set aside as a national park in 1952 and comprises a large portion of the Pembrokeshire coast and its islands and the moorland hills of Mynydd Preseli. Rugged cliffs and coastal rock formations are home to boisterous populations of seabirds, porpoises, whales, seals and dolphins. Cycle, hike or sea kayak around the spectacular coastline. Bird watching and rock climbing are also popular.
