Yr Eifl
Garn Ganol (564m)
Tre'r Ceiri (485m)
Garn For (444m)

The three peaks of Yr Eifl (often called “the rivals” in English) are nestled on the north coast between Nefyn and Trefor. Yr Eifl translates as “the fork”, so it’s quite easy to see where the name came from. The most sea-ward of the three peaks is Garn For (444m) and has been extensively quarried. Granite from here has been used to make curling stones used in the winter Olympics. Garn Ganol is the middle of the three peaks, as the name suggests (canol means centre/middle). This is the highest of the peaks and is also the highest point on the Llŷn Peninsula at 564m high.

The last peak is Tre’r Ceiri which means “town of giants” and is home to one of the best ancient hill forts in Europe. There are many hills with ancient hill fort remains around this part of Wales, but according to most, Tre’r Ceiri is by far the best. Many of the circular huts are still visible and stand several metres high.

At the foot of Yr Eifl to the north-west is Nant Gwrtheyrn, completely surrounded by hills and almost cut off totally from the outside world. This old mining village is now home to the National Language and Heritage Centre for Wales. To the south, Llithfaen sits on the lower slopes of the hills and is the highest village on the peninsula.

From the summit of Yr Eifl the peninsula rolls out in front of you – plus there are fantastic views across the summits of Snowdonia, including Snowdon, the Moelwyn and Cader Idris. On a clear day, the entire coast around Cardigan Bay is visible as well as Anglesey, including Holyhead and even the Wicklow Mountains in Ireland! The walk to the top is quite tough, but the views are well worth it. Most walkers start from the car park on the road to Nant Gwrtheyrn, above Llithfaen, but there are other routes that can be taken – see an ordinance survey map and plan your route carefully. The weather on Yr Eifl can change very quickly, especially if sea mist rolls in off Caernarfon Bay.
