About Llŷn Peninsula
The Llŷn Peninsula stretches 30 miles south-west from Snowdonia into the Irish Sea, terminating at Aberdaron — the embarkation point for Bardsey Island.
Much of the peninsula is an Area of Outstanding Natural Beauty. It is also the heartland of the Welsh language — over 70 percent of residents speak Welsh in some communities.
Porth Dinllaen, halfway down the north coast, is a tiny National Trust hamlet with the famous Tŷ Coch Inn sitting on the sand itself — there is no road in; you walk across the beach.
