About Pen yr Allt-fawr

Perched above the Dyfi Valley near Machynlleth, this 316-metre summit is less of a 'great height' and more of a 'very determined slope.' It offers a quiet, unpretentious vantage point over mid-Wales, far from the frantic, selfie-stick-wielding crowds of the higher northern peaks.

Did You Know?

  • It overlooks the lush Afon Dulas valley, acting as a natural gateway to the southern fringes of the Dyfi Forest's extensive network of winding trails.
  • The fell is situated within the UNESCO Dyfi Biosphere, one of only a few sites in the UK recognized for its unique balance between people and nature.
  • Geologically, the area is composed of Ordovician strata, meaning the ground you are walking on has been around for roughly 450 million years, so please try not to scuff it.
  • Despite its diminutive stature, it served historically as a significant landmark for the local farming community of Cadfarch, marking the transition from valley floor to upland grazing.
  • The summit is so subtly rounded that you may find yourself checking your map several times, only to realize the highest point is actually beneath that one slightly more arrogant-looking tuft of grass.
