Hill range in Wales
the range of hills

The Preseli Mountains (/lang//p//r//ə//'//s//ɛ//l//i/, prəSELee; Mynyddoedd y Preseli or Y Preselau), also known as the Preseli Hills, or just the Preselis, is a range of hills in western Wales, mostly within the Pembrokeshire Coast National Park and entirely within the county of Pembrokeshire. The range stretches from the proximity of Newport in the west to Crymych in the east, some 13 mile (21 km) in extent. The highest point at 1759 feet (536 m) above sea level is Foel Cwmcerwyn. The ancient 8 mile (13 km) of track along the top of the range is known as the Golden Road. The Preselis have a diverse ecosystem, many prehistoric sites, and are a popular tourist destination. There are scattered settlements and small villages; the uplands provide extensive unenclosed grazing, and the lower slopes are mainly enclosed pasture. Slate quarrying was once an important industry. More recently, igneous rock is being extracted. The Preselis have Special Area of Conservation status, and there are three sites of special scientific interest (SSSIs).

A peak is spelt Percelye on a 1578 parish map, and more recent maps show the range as Presely or Mynydd Prescelly. The etymology is unknown, but is likely to involve Welsh prys, meaning "wood, bush, copse". A number of other peaks are shown on the 1578 map, but the only other named peak is Wrennyvaur (now Frenni Fawr). An 1819 Ordnance Survey Map refers to the range as Precelly Mountain (singular). An 1833 publication stated: the ancient Welsh name is Preswylva, signifying "a place of residence", but does not cite any evidence. 21st century maps show the range as Mynydd Preseli.

The hills, much of which are unenclosed moorland or low grade grazing with areas of bog, are surrounded by farmland and active or deserted farms. Field boundaries tend to be earth banks topped with fencing and stock resistant plants such as gorse. located on the southern slopes of the range near the village of Rosebush. To the south is Llys y Fran reservoir. There are no natural lakes in the hills, but a number of rivers, including the Gwaun, Nevern, Syfynwy and Tâf have their sources in the range.

The principal peak at 1759 feet (536 m) above sea level is Foel Cwmcerwyn. There are 14 other peaks over 980 feet (299 m) of which three exceed 1300 feet (396 m). The Preselis have Special Area of Conservation status; the citation states that the area is " exceptional in Wales for the combination of upland and lowland features " Numerous scarce plant and insect species exist in the hills. For example, they are an important UK site for the rare Southern damselfly, Coenagrion mercuriale, where efforts to restore habitat were underway in 2015 and reported in 2020 to have been a success.

One major road, the A478, crosses the eastern end of the range, reaching a height of Two B class roads, intersecting at New Inn, cross the hills: the B4313 NW SE, reaching and the B4329 NE SW, reaching at Bwlch gwynt (translation: windy gap). These, and a number of other minor roads and lanes, provide scenic routes popular with motoring, cycling and walking tourists. The A487 road skirts the western end of the range, near Newport. with walks varying from easy to long distance. The larger part of the hills is designated under the Countryside and Rights of Way Act 2000 as 'open country' thereby enabling walkers the 'freedom to roam' across unenclosed land, subject to certain restrictions. An east west bridleway which runs the length of the main massif (known as Flemings' Way There are cycle trails. Paragliding is not permitted without the consent of the land owners, who in 2014 collectively agreed not to allow it.

Castell Henllys, on the A487 road between Eglwyswrw and Felindre Farchog is a reconstructed Iron Age settlement, illustrating what life may have been like in those times.

The Preselis are dotted with prehistoric remains, including evidence of Neolithic settlement. More were revealed in an aerial survey during the 2018 heatwave. Samuel Lewis's A Topographical Dictionary of Wales published in 1833 said of Maenclochog parish:Part of the Precelly mountain, which is the highest in South Wales the ancient Welsh name of this mountain is Preswylva, signifying "a place of residence," and is derived from its having been the resort of the natives, as a place of security, in the intestine [sic] wars by which this part of the principality was agitated during the earlier periods of its history. This mountain was anciently well clothed with forest timber, affording shelter to such as took refuge in its recesses, but now presents a bare and sterile aspect, dreary in its appearance, and exhibiting some small vestiges of ancient encampments, which were probably those constructed by the natives. Pollen analysis suggests that the hills were once forested but the forests had been cleared by the late Bronze Age. and later geologists suggested that Carn Menyn (formerly called Carn Meini) was one of the bluestone sources. Recent geological work has shown this theory to be incorrect. It is now thought that the bluestones at Stonehenge and fragments of bluestone found in the Stonehenge "debitage" have come from multiple sources on the northern flanks of the hills, such as at Craig Rhos y felin. Advanced details of a recent contribution to the puzzle of the precise origin of the Stonehenge bluestones were published by the BBC in November 2013. Others theorise that bluestone from the area was deposited close to Stonehenge by glaciation. More detailed discussions on the bluestone topic can be found in the Stonehenge, Theories about Stonehenge and Carn Menyn articles. Investigations published in 2021 suggested a link between Waun Mawn (see below) and the Stonehenge bluestones, but this was disputed in a 2024 study.

Slate quarrying was once an important industry in the Preselis; the former quarries, worked for much of the 19th century, can still be seen in a number of locations such as Rosebush. Preseli slate was not of roofing quality, but its density made it ideal for machining for building and crafts. Most quarries had closed by the 1930s but there is a workshop at Llangolman where slate is still used to make a variety of craft items. During the Second World War, the War Office used the Preselis extensively for training exercises by British and American air and ground forces. Its proposed continued use after the war was the subject of a two year ultimately successful protest by local leaders. The success of the protest was commemorated 60 years on, in 2009, with a plaque at each end of the Golden Road: one at the foot of Foel Drygarn near Mynachlog ddu, and another near the B4329 at Bwlch gwynt. In 2000, Terry Breverton, a lecturer at Cardiff University, in promoting a book he had published, suggested that the rock star Elvis Presley's ancestors came from the Preselis and may have had links to a chapel at St Elvis.
