Mynydd Carnguwch

About Mynydd Carnguwch

Rising sharply above the Llŷn Peninsula, Mynydd Carnguwch is essentially a very large Bronze Age burial heap masquerading as a mountain. Its summit cairn is so unnervingly enormous that one suspects the ancient residents were either very bored or extremely keen on keeping the deceased pinned down.

Key Statistics

Did You Know?

• •The summit is crowned by an immense Bronze Age cairn, measuring approximately 30 metres across and 6 metres high. It remains one of the most significant and well-preserved prehistoric monuments in North Wales.
• •Geologically, the fell is a resistant plug of microgranite that survived the heavy glaciation of the Llŷn Peninsula. This gives it a distinct conical shape that stands out clearly against the surrounding coastal lowlands.
• •From the top, you can see the three peaks of Yr Eifl to the north and the sweeping curve of Cardigan Bay to the south. On exceptionally clear days, the silhouette of Ireland's Wicklow Mountains appears on the horizon.
• •Local folklore attributes the massive rock pile to a giantess who was carrying stones in her apron when the string snapped. It is a much more poetic explanation than the historical reality of thousands of people hauling rocks up a steep slope.
• •The ascent involves navigating a dense defense of gorse and bracken that acts as nature’s own barbed wire. You will likely reach the summit looking like you’ve lost a wrestling match with a very angry, very prickly hedge.
