The highest point of Gower is The Beacon at Rhossili Down at overlooking Rhossili Bay. Pwll Du and the Bishopton Valley form a statutory Local Nature Reserve. 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.
