Stackpole and Castlemartin is a community situated approximately 4 miles south of Pembroke in southwest Pembrokeshire, Wales, primarily within the Pembrokeshire Coast National Park. This positioning places it along the southern coastline of the Pembrokeshire Peninsula, contributing to its administrative role in the region's coastal management. The community is cantered around coordinates 51°36′N 4°54′W.] Formed in 2011 by the amalgamation of the former Stackpole and Castlemartin communities under The Pembrokeshire (Communities) Order 2011, the area encompasses 5,428 hectares (approximately 21 square miles) and includes villages such as Bosherston, St. Twynnells, and Stackpole. Its boundaries, delineated on official maps deposited with Pembrokeshire County Council, extend to incorporate coastal stretches from Stackpole Quay in the west to Linney Head in the east. These boundaries follow natural and infrastructural features, such as roads and watercourses per standard administrative conventions.
The physical landscape of Stackpole and Castlemartin in Pembrokeshire, Wales, is characterised by a dramatic coastal zone and varied inland terrain, shaped by geological processes over millions of years. The area features prominent limestone cliffs along the shoreline, rising sharply from the sea and forming natural amphitheaters such as those at Stackpole Quay. These cliffs, rising to 40-80 meters in height, are interspersed with sandy beaches and expansive dunes; notable examples include the pristine Barafundle Bay, a west-facing crescent of fine sand backed by marram grass-stabilized dunes, and Broadhaven South, known for its secluded coves. This coastal stretch forms a key segment of the Pembrokeshire Coast National Park and is traversed by the Pembrokeshire Coast Path, a 186-mile long-distance footpath that highlights the area's rugged beauty and accessibility for walkers.
