Gower is a peninsula reaching into the sea between Swansea Bay and Carmarthen Bay. It was the first designated Area of Outstanding Natural Beauty in 1956. It covers 188 kilometers in all.
The AONB has a large number of Sites of Special Scientific Interest, as well as three National Nature Reserves, two Local Nature Reserves and a Ramsar Wetlands site.
Dolphins and porpoises swim off the coast.
Visitors can enjoy surfing, hiking, bicycling and guided tours through the varied coastline and limestone cliffs on the north side, and sandy dunes and saltwater marshes on the south side. There is deciduous, mainly oak, woodland and traditional agricultural farmland to be explored.
The western side of the Peninsula is noted for its Neolithic and Bronze Age features and its surviving medieval open field system.
