The Preseli Hills or, as they are known locally and historically, Preseli Mountains (Welsh: Mynyddoedd y Preseli / Y Preselau—also spelt Presely or Mynydd Prescelly) is a range of hills in north Pembrokeshire, West Wales, mostly within the Pembrokeshire Coast National Park.
The range stretches from Dinas Island, Cardigan Bay to Frenni Fach, near Crymych approximately 13 miles (20 km) to the east. The ancient 8-mile (13 km) 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.
The mountains, 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.
The principal peak at 1,759 feet (536 m) above sea level is Foel Cwmcerwyn. There are 14 other peaks over 980 feet (300 m) of which three exceed 1,300 feet (400 m). The 15 peaks, with notes on their features, are listed in the table below, accessed by clicking on the 'show' link.
Villages and other settlements within the range are Blaenffos, Brynberian, Crosswell, Crymych, Cwm Gwaun, Dinas Cross, Glandy Cross, Mynachlog-ddu, New Inn, Pentre Galar, Puncheston, Rosebush and Tafarn-y-Bwlch. The principal town in the area is Newport, on the flank of the Carningli-Dinas upland.
