Across the channel into South Wales, Glamorgan (to the east) has better beaches but the sea-water is often a muddy colour. Proceeding westwards, the beaches and coastline improve considerably. The best beaches in this area are those on the Gower peninsula (west of Swansea) and also Pembrey in Carmarthenshire. The popular beaches with good facilities are Barry Island, Porthcawl (Trecco Bay and Sandy Bay) and Aberavon. Quieter sandy beaches with some facilities can be found at Southerndown, Langland Bay, Caswell Bay, Port Eynon and Pembrey. For secluded beaches try Temple Bay, Pwlldu Bay, Crawley, Blue Pool Bay or Scott's Bay. For a day out with plenty to explore try Southerndown, Merthyr Mawr, Three Cliffs Bay, Whiteford Sands or Pembrey Beach.
