Yr Eifl

Yr Eifl is a mountain on the Lleyn peninsula in north-western Wales. It has three summits, each quite separate from the others, which is often supposed to be the source of the alternative English name The Rivals, but this is merely an anglicised form of Yr Eifl. The central summit is the highest, and houses the trig point; the northern summit is the lowest and has a radio transmitter on it, as well as quarries, and a cliff face leading down to the Irish Sea. The third summit, on the south-eastern side, is intermediate in height, at 485 m, and is the location of the Iron Age hill fort Tre'r Ceiri. Routes lead onto the hill from Llithfaen, Llanaelhaearn and Trefor. On the west side of Yr Eifl, is a small valley leading down to the sea. This is Nant Gwrtheyrn ("Vortigern's Valley"), a valley with no public roads, which is now home to a Welsh-language teaching centre. On a clear day, the views from the summit reach 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.
