The Pembrokeshire Coast Path, often called the Pembrokeshire Coastal Path, is a designated National Trail in Pembrokeshire, southwest Wales. Established in 1970, it is a 186-mile (299 km) long-distance walking route, mostly at cliff-top level, with a total of 35,000 feet (11,000 m) of ascent and descent. At its highest point – Pen yr afr, on Cemaes Head – it reaches a height of 574 feet (175 m), and at its lowest point – Sandy Haven crossing, near Milford Haven – it is just 6 feet (2 m) above low water. Whilst most of the coastline faces west, it offers – at varying points – coastal views in every direction of the compass.
The Manx shearwater is a medium-sized shearwater in the seabird family Procellariidae. The scientific name of this species records a name shift: Manx shearwaters were called Manks puffins in the 17th century. Puffin is an Anglo-Norman word for the cured carcasses of nestling shearwaters. The Atlantic puffin acquired the name much later, possibly because of its similar nesting habits.
Skokholm or Skokholm Island is an island 2.5 miles (4.0 km) off the coast of Pembrokeshire, Wales, south of the neighbouring island of Skomer. The surrounding waters are a marine reserve and all are part of the Pembrokeshire Coast National Park. Both islands are listed as Sites of Special Scientific Interest.
Grassholm or Grassholm Island is a small uninhabited island situated 13 kilometres (8 mi) off the southwestern Pembrokeshire coast in Wales, lying west of Skomer, in the community of Marloes and St Brides. It is the westernmost point in Wales other than the isolated rocks on which the Smalls Lighthouse stands. Grassholm is known for its huge colony of northern gannets; the island has been owned since 1947 by the Royal Society for the Protection of Birds, and is one of its oldest reserves. It reaches 42 metres (138 ft).
Gateholm or Gateholm Island is a small tidal island off the south west coast of Pembrokeshire, in the community of Marloes and St Brides, in the south west side of Wales, in the west of the UK, and about 8 miles (13 km) west of the port of Milford Haven. It is known for its Romano-British remains. Gateholm is owned by the National Trust as part of their Marloes Sands and Mere estate.
Middleholm, also known as Midland Isle, is a small island lying off southwest Pembrokeshire in Wales, between the island of Skomer and the mainland in the community of Marloes and St Brides. It is roughly circular with a diameter of about 1,210 feet (370 m) and an area of 21.5 acres (8.7 ha). It is separated from the mainland by Jack Sound and from Skomer by Little Sound.
Ramsey Island is an island about 1 kilometre off St David's Head in Pembrokeshire on the northern side of St Brides Bay, in southwest Wales, in the community of St Davids and the Cathedral Close. It is 259 hectares in area. Ramsey means Hrafn's island.
Bardsey Island, known as the legendary "Island of 20,000 Saints", is located 1.9 miles (3.1 km) off the Llŷn Peninsula in the Welsh county of Gwynedd. The Welsh name means "The Island in the Currents", while its English name refers to the "Island of the Bards", or possibly the Viking chieftain, "Barda". At 179 hectares in area it is the fourth largest offshore island in Wales, with a population of 11.
Cardigan Island is an uninhabited island north of Cardigan, Ceredigion, south-west Wales. It reaches a height of 52 metres (171 ft) a.s.l., and 38 acres (15 ha) in area.
St Brides Bay is a bay in western Pembrokeshire, West Wales.
St Margaret's Island is a small tidal island to the northwest of Caldey Island in Carmarthen Bay, Pembrokeshire, Wales.
Annet is the second largest of the fifty or so uninhabited Isles of Scilly, 1 kilometre (0.62 mi) west of St Agnes with a length of 1 kilometre (0.62 mi) and approximately 22 hectares in area. The low-lying island is almost divided in two by a narrow neck of land at West Porth which can, at times, be covered by waves. At the northern end of the island are the two granite carns of Annet Head and Carn Irish and three smaller carns known as the Haycocks. The rocky outcrops on the southern side of the island, such as South Carn, are smaller. Annet is a bird sanctuary and the main seabird breeding site in Scilly.
Marloes is a village and parish in Pembrokeshire, Wales, on the Marloes Peninsula 7 miles (11 km) west of Milford Haven and forms the western tip of the southern shore of St Brides Bay. It is within part of the Pembrokeshire Coast National Park. The parish has 6 miles (9.7 km) of mainland coastline accessible throughout by the Pembrokeshire Coast Path and, together with St Brides, constitutes the community of Marloes and St Brides. In 2001, the population was 323.
Ronald Mathias Lockley was a Welsh ornithologist and naturalist. He wrote over fifty books on natural history, including a major study of shearwaters, and many articles. He is perhaps best known for his book The Private Life of the Rabbit.
Skomer Marine Conservation Zone is an underwater marine nature reserve located off the coast of Pembrokeshire in Wales. The nature reserve completely surrounds the islands of Skomer and Middleholm, and encompasses the mainland coastline around the end of the Marloes peninsula, including the small bay of Martin's Haven.
The Sea Empress oil spill occurred at the entrance to the Milford Haven Waterway in Pembrokeshire, Wales on 16 February 1996. The Sea Empress was en route to the Texaco oil refinery near Pembroke when she became grounded on mid-channel rocks at St. Ann's Head. Over the course of a week, she spilt 72,000 tons of crude oil into the sea. The spill occurred within the Pembrokeshire Coast National Park – one of Europe's most important and sensitive wildlife and marine conservation areas. It was Britain's third largest oil spillage and the twelfth largest in the world at the time.
The coastline of Wales extends from the English border at Chepstow westwards to Pembrokeshire then north to Anglesey and back eastwards to the English border once again near Flint. Its character is determined by multiple factors, including the local geology and geological processes active during and subsequent to the last ice age, its relative exposure to or shelter from waves, tidal variation and the history of human settlement and development which varies considerably from one place to another. The majority of the coast east of Cardiff in the south, and of Llandudno in the north, is flat whilst that to the west is more typically backed by cliffs. The cliffs are a mix of sandstones, shales and limestones, the erosion of which provides material for beach deposits. Of the twenty-two principal areas which deliver local government in Wales, sixteen have a coastline, though that of Powys consists only of a short section of tidal river some distance from the open sea. Its length has been estimated at 1,680 miles (2,700 km).
The geology of Pembrokeshire in Wales inevitably includes the geology of the Pembrokeshire Coast National Park which extends around the larger part of the county's coastline and where the majority of rock outcrops are to be seen. Pembrokeshire's bedrock geology is largely formed from a sequence of sedimentary and igneous rocks originating during the late Precambrian and the Palaeozoic era, namely the Ediacaran, Cambrian, Ordovician, Silurian, Devonian and Carboniferous periods, i.e. between 635 and 299 Ma. The older rocks in the north of the county display patterns of faulting and folding associated with the Caledonian Orogeny. On the other hand, the late Palaeozoic rocks to the south owe their fold patterns and deformation to the later Variscan Orogeny.
The Skomer Volcanic Group is a Silurian lithostratigraphic group in Pembrokeshire, Wales. The name is derived from the island of Skomer off the west coast of Pembrokeshire. It was traditionally known as the Skomer Volcanic Series. The rocks are exposed across the island of Skomer and along the northern half of the nearby Marloes peninsula as far east as St Ishmaels.
