Whistling Sands

Traeth Porthor, also known as Whistling Sands, is one of Wales' most intriguing beaches, nestled on the northern coast of the Llŷn Peninsula. The beach earned its evocative nickname from the peculiar squeaking or whistling sound the sand makes underfoot when walked on – a rare phenomenon caused by the unique shape and size of the sand grains rubbing against each other.

This west-facing beach boasts a sweeping crescent of pristine white sand backed by grassy cliffs, offering spectacular views across the Irish Sea. The beach is owned and managed by the National Trust, ensuring its preservation as a natural beauty spot. Its clear waters and reliable waves make it popular with swimmers and surfers alike, while the surrounding headlands provide excellent walking opportunities with breathtaking coastal views.

Despite its remote location in Gwynedd, Traeth Porthor offers good facilities including a cafe, toilets, and parking, making it accessible for day-trippers. The beach is particularly stunning at sunset, when the unique acoustics of the sand combine with the golden light to create an almost magical atmosphere.

For visitors seeking the best experience of the whistling sand, it's worth noting that the effect is most pronounced when the sand is dry and you scuff your feet along it – a quirky natural feature that makes this beach truly one of a kind in Wales.
