Complex geology gives a wide variety of scenery in a relatively small area. It ranges from the south coast's superb carboniferous limestone cliffs and beaches between the Mumbles to Worms Head to the dune systems and wide beaches of the West and salt-marshes in the north. Inland, the most prominent features are the large areas of common, dominated by sandstone heath ridges including the soaring sweep of Cefn Bryn. Secluded valleys have rich deciduous woodland and the traditional agricultural landscape is a patchwork of fields characterised by walls, stone-faced banks and hedgerows. Gower has been settled since prehistoric times and has a high concentration of ancient Neolithic and Bronze Age sites. The public rights of way network is extensive covering 431 km (268 miles) and is heavily used by both visitors and locals.
