The Pembrokeshire Coast National Park in South Wales is one of the UK's best kept secrets - it's Britain's only truly coastal National Park. People here have shaped the landscape over the centuries, leaving their mark in tombs and castles, crosses and cottages, quarries and quays. It is a spectacular landscape of rugged cliffs, sandy beaches, wooded estuaries and wild inland hills.
