Gower Peninsula. In 1956, Gower became the first area in the United Kingdom to be designated an Area of Outstanding Natural Beauty. About 70 square miles (180 km2) in area, Gower is known for its coastline, popular with walkers and outdoor enthusiasts, especially surfers. Gower has many caves, including Paviland Cave and Minchin Hole Cave. The highest point of Gower is The Beacon at Rhossili Down at 193 metres (633 ft) overlooking Rhossili Bay. The interior of Gower consists mainly of farmland and common land. The population resides mainly in villages and small communities. The southern coast consists of a series of small, rocky or sandy bays, such as Langland and Three Cliffs, and larger beaches such as Port Eynon, Rhossili and Oxwich Bay. The north of the peninsula has fewer beaches, and is home to the cockle-beds of Penclawdd.
