Cefn Bryn, the backbone of the Gower Peninsular runs for 5 miles, made of old red sandstone, it is liberally seeded with large pieces of quartz conglomerate that was left from the receding ice sheets of the last ice age. Many of the Gower cottages have walls built of this reddish / pink quartz conglomerate which glistens like so many diamonds in the sun. The Gower Peninsular, the first area in the UK designated an Area of Outsanding Natural Beauty in 1956. Strict planning regulations ensure this natural beauty is available to the many visitors who enjoy the scenary and beautiful walks all year round. To the south is the broad sandy sweep of Oxwich Bay, with Three Cliffs Bay just to the eastern end. Looking north, the wide expanse of the Loughor Estuary and the cockle beds of Penclawdd. Just behind the headland of Oxwich and above the western edge of the beach, you can just make out Lundy Island some 38 miles away on the horizon. There are some 60 cairns scattered throughout the area, though some of these 60 are attributed to farmers collecting and clearing rocks from their fields. Additionally, there are ancient hill forts, megaliths and neolithic tombs and castles to be found all around Gower. Notable visitors from history are said to include King Edward I in 1284, King Henry VII on his way to the Battle of Bosworth Field in 1485, and according to legend King Arthur too.
