Did You Know?

  • The name Hirfynydd is a compound of the Welsh 'hir' (long) and 'mynydd' (mountain), providing a literal topographical description of the hill's characteristic profile.
  • With a topographic prominence of at least 150 metres, it is classified as a Marilyn, ensuring that its summit provides a commanding and unobstructed view of the surrounding terrain.
  • The high ground here is famously associated with Sarn Helen, an ancient Roman road; the straightness of the path across the ridge is a lingering hallmark of Roman engineering that walkers can still follow today.
