Carnedd Llewelyn

Carnedd Llywelyn is a mountain summit in Gwynedd that rises to 1064 meters, making it Wales's third highest peak. The mountain connects to four distinct ridges and offers several climbing approaches from different starting points.

An RAF Avro Lincoln aircraft crashed on the mountain in March 1950 during a night training exercise, killing all six crew members. This tragic event left its mark on the mountain's history.

The name comes from Welsh and means Llywelyn's cairn, honoring a historical Welsh prince. Locals and visitors often speak of this connection when discussing the mountain.

The mountain is accessible from multiple starting points, with the most direct route beginning near Bethesda. Wear sturdy boots and bring weather protection, as conditions at this elevation can change quickly.

Just below the main summit sits Llyn Llyffant, Wales's highest natural lake tucked into a hollow. This hidden water feature surprises many climbers who reach the plateau.
