Carnedd Dafydd
Carnedd Dafydd is one of the great summits of Snowdonia, standing at 1044 metres above sea level and ranking as the second highest peak in Wales and indeed in all of England and Wales, surpassed only by Snowdon itself. Named after Dafydd ap Gruffudd, the last native Prince of Wales, the mountain occupies a commanding position within the Carneddau massif, the largest high mountain plateau in Wales and arguably in all of Britain south of the Scottish Highlands. It is a mountain of considerable grandeur and seriousness, attracting hillwalkers, mountaineers and those who seek genuinely remote and wild terrain far removed from the crowds that gather around Snowdon. Its summit cairn sits on the edge of formidable northern cliffs that plunge into deep cwms, lending the peak a dramatic and somewhat intimidating character that distinguishes it from gentler Welsh hills.
The Carneddau range as a whole is steeped in the history of medieval Wales, and Carnedd Dafydd specifically carries the name of Dafydd ap Gruffudd, who was executed by Edward I of England in 1283 following the collapse of Welsh independence. His brother, Llywelyn ap Gruffudd, gives his name to the neighbouring summit of Carnedd Llywelyn, which stands slightly higher just to the north. Together the two peaks serve as a lasting memorial to the last princes of an independent Wales. The landscape they inhabit was the heartland of Gwynedd, the most powerful of the Welsh kingdoms, and the high Carneddau ridges would have been familiar terrain to Welsh princes and their retinues moving through the mountains. The area also has prehistoric significance, with ancient Bronze Age cairns and burial mounds scattered across the plateau, attesting to human presence and ritual activity stretching back thousands of years.
In terms of physical character, Carnedd Dafydd presents a broad, rocky summit plateau with a large, well-built cairn marking the highest point. The going underfoot transitions between grassy moorland, loose scree and solid rock as the terrain changes with altitude. The northern edge of the summit is defined by impressive cliffs above Cwm Llafar, a profound and shadowy hollow that holds snow well into spring and creates a vivid contrast with the open ridges. The mountain can feel genuinely exposed and austere in poor weather, with the wind driving cold and wet off the Irish Sea with surprising ferocity. On clear days, however, the views are extraordinary, stretching from Snowdon in the south to the Isle of Man on the horizon, across the Menai Strait to Anglesey, and north along the coast towards the Great Orme.
The surrounding landscape is dominated by the broad, rolling Carneddau plateau, a place of wide skies, tawny grasses and ancient rocks that feels genuinely remote even by Welsh mountain standards. To the north lies the slightly higher Carnedd Llywelyn, connected by a broad ridge, while to the west the long ridge descends toward Pen yr Ole Wen above the Ogwen valley. The Ogwen valley itself, accessible via the A5, is one of the classic mountain valleys of Wales, home to Llyn Ogwen, the Idwal Slabs and the dramatic cirque of Cwm Idwal. The Carneddau are also known for their semi-feral Welsh mountain ponies, a herd that has roamed the high plateau for centuries and is widely considered one of the oldest and most genetically distinct pony populations in Britain. Encountering them on the open ridge is one of the memorable and unexpected pleasures of walking in this part of Snowdonia.
The most popular approach to Carnedd Dafydd begins from the Ogwen valley, particularly from the car park at Ogwen Cottage near Llyn Ogwen on the A5 road between Bethesda and Capel Curig. From here a path climbs steeply via Pen yr Ole Wen before following the broad ridge eastward to the summit, a route that is strenuous but clearly defined and rewarding. An alternative approach follows the valley of Afon Llafar from Bethesda to the north, a longer and less frequented route through the remote cwm beneath the northern cliffs. The mountain falls within the Snowdonia National Park and requires no special access permissions, though walkers should be properly equipped with appropriate footwear, clothing and navigation tools, as the plateau can be featureless and disorienting in mist. The best conditions tend to occur from late spring through early autumn, though the high Carneddau can be walked in winter by those with experience in mountain navigation and the use of ice axe and crampons when required.
A particularly fascinating aspect of Carnedd Dafydd is its connection to the wider Carneddau wild pony herd, which is actively managed by the National Trust and local farmers through an annual autumn gather that has become something of a cultural event in the region. The herd's origins are disputed but some estimates suggest continuous habitation of the plateau for over a thousand years. The mountain also sits close to the Aber Falls National Nature Reserve to the north, one of the finest waterfalls in Wales, and the broader Carneddau range has been proposed and recognised as exceptional habitat for ring ouzel, merlin and other upland species increasingly rare elsewhere in Britain. For those willing to invest the effort, Carnedd Dafydd rewards with a genuine sense of achievement and a profound connection to both the wild natural landscape and the deep historical currents of Welsh identity.
