Of Britain's twelve National parks, only the Pembrokeshire National Park is predominantly coastal, covering 186 miles from St Dogmael's near Cardigan to Amroth in the south. Further eastward along the Carmarthenshire coastline we traverse beaches and estuaries, reaching the trademark limestone cliffs of the Gower Peninsula, which was named Britain's first Area of Outstanding National Beauty in 1956. As we reach the very perimeter of the region the coastland then approaches the urban habitats of Swansea.
