Seascape Types: THIR, THMR Key Characteristics A rocky, fine grain indented sandstone coast with spectacular high cliffs rising to 150m with islets and arches, jagged rocky shores and very few small shingle beaches. Rural coastal plateau predominantly pastoral with very sparse settlement set back from the coast or in deep valleys. The coast has little light pollution. An exposed outward facing coast. Views from coastal path, Ceibwr Bay, and associated open access land. Key cultural associations: sparsely populated; dominant characteristic is of an evolved and unspoiled landscape

Physical Geology Ordovician rocks with a sandstone lithology. Characteristics Coastal landform A rocky, fine grain indented west and north west facing eroding coast. Spectacular high cliffs abut the coast rising to 150m AOD around Pen yr Afr and near Foel Goch. These are formed from steeply angled sandstone beds which create jagged formations, including steeply sloping cliffs, islets at Careg Wylan and Careg Yspar and a natural arch nearby. Narrow incised valleys reach the coast at only two small inlets which is otherwise fairly raised rising to 189m AOD. Coastal landcover A rural coast with semi-natural vegetation on steep coastal slopes and cliffs. Agriculture is predominantly pastoral with some arable in parts and reaches the coast where cliffs are vertical. Settlement is very sparse and scattered usually set back from the exposed coast. Intertidal area Narrow jagged rocky shores cover the vast majority of the coastline with occasional small shingle beaches. Islets lie just offshore linked at low tide. Characteristics of sea Exposed and tidal. Hinterland landform Behind the coastal hills to the east the dissected hilly plateau remains at a consistent level (200m AOD maximum) incised by narrow valleys which reach the coast in a couple of locations including . To the south the undulating profile of the Carningli and other hills rise to around 340m AOD providing a distinct backcloth. Hinterland landcover A rural hinterland with predominantly pastoral agriculture with some arable in parts. Deciduous woodland lies in steep incised valleys back from the coast. Semi-natural moorland vegetation is limited to the foothills of the Preselis to the south. Settlement is sparse and scattered with only one small village between the main settlements of Cardigan to the north and Newport to the south i.e. Moylgrove. Lighting The greater part of the coast is dark with minor light sources concentrated around the Teifi estuary to the north and Newport to the south.

Use Land/coast uses Pastoral farming with some limited arable interspersed with sparse residential uses/farmsteads. The coastal path runs along the entire coastal unit. Sea uses Leisure/sailing boats from Teifi estuary, Newport and .

Visual and How the seascape unit Coast Path, minor road network, scattered settlement and open access land at sensory qualities is experienced a distance to the south including Mynydd Carningli. Degree of intervisibility The most significant visibility is from the coastal edge including highpoints and slopes. The of land and sea incised coastal plateau character of the hinterland means that visibility inland is limited particularly to the east. To the south, the Preseli foothills overlook the sea e.g. Mynydd Carningli. Key views to sea and Coastal path, Ceibwr Bay, Crugiau Cemmaes viewpoint inland, Mynydd Carningli and along the coast associated open access land. Key views to land From occasional sailing boats/leisure craft.
