Views, walking and archaeology on Yr Eifl

Looking at Yr Eifl from Dinas Dinlle beach

Enjoy spectacular seascapes, wonderful wildlife and phenomenal prehistoric hill forts on the highest point on the peninsula.

Yr Eifl (non NT) is a mountain on the north coast of the Llŷn Peninsula. It features three summits, quite separate from each other. The peaks are also known as ‘the Rivals’ in English, but this is merely an anglicised form of Yr Eifl, meaning 'the forks' or 'the strides' in Welsh.

Three peaks

  • Tre'r Ceiri, 485 metres (1,591 ft)
  • Garn Ganol, 564 metres (1,850 ft)
  • Garn For, 444 metres (1,457 ft)

Tre'r Ceiri: Town of the giants

If you visit only one Iron Age site in Wales, perhaps it should be the spectacular hill fort of Tre'r Ceiri, meaning 'Town of the Giants'. It is often said to be the most impressive hill fort in north Wales.

Few Welsh prehistoric sites capture the imagination as powerfully. At over 450 meters above sea level, this special place encloses over 150 visible stone houses with significant stone ramparts surviving in places to near full height.

The summit is occupied by a substantial early Bronze Age burial cairn, clearly preserved and respected within the later hill fort. The views are exceptional too.

Garn Ganol: The highest point on the peninsula

The walk up to Garn Ganol is in three stages: grassy slopes, then rocky lumpy ground, and finally steep loose rocky slopes near the summit. The views are, needless to say, spectacular from the top.

On a clear day, you can see as far as the Isle of Man, the Wicklow Mountains in Ireland and the Lake District, as well as the entire sweep of Cardigan Bay to the south.

Garn For: Olympic stones

This hill has been extensively quarried. Granite from it has been used to pave streets in Lancashire's towns and cities and as curling stones in the Olympics.

Go walking

Walking up Yr Eifl is quite tricky in a couple of places, so be careful. It is important to wear attire compatible with mountain trekking as temperature and wind conditions can be deceiving.

Nant Gwrtheyrn

On the western slopes, beneath the menacing shadow of Graig Ddu (a cliff on the west slope of Garn Ganol), is a small valley leading down to the sea. This is Nant Gwrtheyrn, an enchanting former quarrying village, which is now home to a Welsh-language teaching centre where you’ll discover Wales’s most magical legends and history.

Mountain views

The view of Yr Eifl is especially striking from the south west coast of Anglesey, for instance from Llanddwyn Island. The three peaks can also be seen from the major mountains of north-western Snowdonia.
