Caernarfon
A World Heritage walled town built around Edward I's grandest castle, on the Menai Strait where the Llŷn Peninsula begins. Caernarfon blends Roman fort, medieval fortress and a lively harbour-front food scene, and sits within reach of Snowdon's western paths, the Llŷn's beaches and the Anglesey bridges.
