Nant Gwrtheyrn Circular Walk
Where the land meets sea, this walk explores one of the most spectacular spots on the Llŷn Peninsula, the beautiful, secluded valley of Nant Gwrtheyrn. Abandoned when the local quarries closed, the village of Nant Gwrtheyrn sits in the shadow of the Yr Eifl mountain range and is steeped in local legend and folklore. The former Victorian quarrying village is now home to the National Welsh Language and Heritage Centre, where if history is your cup of tea you can learn more about the heritage of the area and the quarrymen who populated it in times gone by.
The walk follows in part the Wales Coast Path past the remnants of what was once a port above the beach. The path climbs high above the beach through an area of protected ancient coastal woodland towards Penrhyn Glas Quarry on the opposite headland of the bay before returning through farmland with views of the Yr Eifl mountain range.
