Yr Eifl

About Yr Eifl

Perched dramatically above the Llŷn Peninsula, Yr Eifl is a trio of peaks that look like they’ve been sculpted for a fantasy epic. Home to the staggeringly well-preserved Tre’r Ceiri hillfort, it’s the ideal spot to feel ancient while questioning your cardio choices.

Did You Know?

• •Tre’r Ceiri is one of Britain’s best-preserved Iron Age hillforts, featuring over 150 stone hut circles still standing at chest height. It’s so remarkably intact that you might find yourself looking for a prehistoric Airbnb listing among the ruins.
• •The peaks are composed of hard microgranite, which was extensively quarried to provide paving setts for the streets of Northern England. You are essentially hiking on the raw material of a Victorian Manchester pavement.
• •The English name 'The Rivals' is a phonetic corruption of the Welsh 'Yr Eifl,' which refers to 'The Forks.' It sounds like a competitive sports league, but the mountains are actually quite cooperative neighbours.
• •From the summit of Garn Ganol, you can occasionally see the Wicklow Mountains in Ireland across the sea. It’s an excellent place to stare intensely at the horizon and pretend you can spot a specific pub in Dublin.
• •The path down towards Nant Gwrtheyrn is famously steep and unforgiving on the human skeletal system. If your knees don't sound like a bowl of Rice Krispies by the bottom, you’ve clearly missed the authentic experience.
