The Brecon Beacons are a mountain range and national park in South Wales, United Kingdom, designated as a national park in the mid-20th century and known for upland moorland and ridges.

The area is best known for its walking and hiking routes across moorland plateaus and steep ridges, with the highest summit, Pen y Fan, reaching 886 m. The park also contains reservoirs, caves, waterfalls and habitats for upland flora and fauna, and offers routes of varying difficulty from short walks to full-day ridge traverses.

Human activity in the area spans prehistoric and historic periods; there are standing stones and Iron Age hillforts on several summits. Over the 19th and 20th centuries the hills became established as a destination for outdoor recreation and hillwalking.

Geographically the Brecon Beacons cover a swath of central southern Wales centered on the market town of Brecon, with easy road access from the A470 and nearby towns and cities in Wales.

  • Highest point: 886 m at Pen y Fan, the highest peak in the Brecon Beacons
  • Access: Storey Arms on the A470 and the market town of Brecon are primary access points for the central ridge and main hiking routes
