Porth Oer (Whistling Sands): This small, picturesque National Trust beach, backed by steep grassy cliffs, is on the Llŷn Heritage Coast. It’s famously known as ‘Whistling Sands’, a nickname based on the sound the granules make underfoot when you walk over its gleaming sand. The sound is created due to the shear stress of weight that is put upon the sand, there are only two beaches in the whole of Europe where you can experience this for yourselves.
