About Cyrniau y Llyn
Rising above the remote upper Ceiriog Valley, this 518m Tump offers a quiet escape within the Berwyn range. Its heather-topped summit provides a distinct vantage point over Llyn Ceiriog, with the grander heights of Cadair Berwyn looming to the southwest. Expect rougher, trackless terrain typical of these less-trodden Welsh moorlands.

Did You Know?
- •The name is Welsh for 'Horns of the Lake,' a reference to its position overlooking Llyn Ceiriog, a small reservoir tucked into the valley to the south.
- •From the summit, you can trace the line of the Ceiriog Valley as it winds eastwards, with the prominent ridge of Godor clearly visible across the water.
- •The hill is located near the famous Wayfarer’s Pass, a high crossing point once used by drovers and later named after the 20th-century cycling journalist Walter MacGregor Robinson.
- •Despite being a distinct summit, it is often treated as a mere shoulder for those heading toward the higher, bog-heavy plateau of Moel Fferna.
- •In typical Berwyn fashion, the 'lake' that gives the hill its name is often more prominent in name than in sight if the Welsh mist decides to settle into the valley below.
