Arfordir Cymru

Llanberis i Trefor is an episode‑length programme that forms part of a series dedicated to exploring Welsh locales. The installment presents a focused look at a particular stretch of coastline, offering viewers a chance to see the region through a clear, on‑the‑ground perspective. In this episode, presenter Bedwyr Rees sets off along the Llyn coastal path, walking the route that runs from Caernarfon down to Porthmadog. As he makes his way, he turns his attention to the names that dot the landscape, probing the origins and meanings behind each one. Alongside the linguistic clues, Rees also delves into the historical backdrop that has shaped the area, linking present‑day landmarks to events and stories from the past. The journey is framed by the natural beauty of the coastline, but the core of the episode remains the investigation of place‑names and the history they conceal. By tracing the path between the two towns, Rees provides a concise yet thorough account of how language and heritage intertwine along this stretch of Wales. The episode therefore serves as both a travelogue and a concise historical survey, guiding the audience through the scenic route while shedding light on the cultural layers that define it.
