Porth Oer (Whistling Sands)
Gwynedd
Porth Oer, better known as Whistling Sands, sits on the northern coast of the Llyn Peninsula in a crescent-shaped cove cradled within high grassy cliffs. The beach is famous for its sand, which produces a distinctive squeaking sound underfoot when dry — a geological curiosity caused by the unusual shape of the sand grains. Access is via a short steep path from the National Trust car park, and the clear water and enclosed setting give the cove an intimate, sheltered character on calm days.\n\nThis dog friendly beach does not permit dogs from April to September, making it an autumn and winter destination for dog walkers. Outside the restriction period, the cove is wonderfully quiet, with clean mineral air rising from the wet sand and the enclosed cliffs concentrating the coastal atmosphere. The firm cove floor is easy going for most dogs, and the Wales Coast Path runs in both directions from the car park, making it an excellent base for a longer walk with a beach section built in. The seasonal restriction is worth respecting — the beach more than repays patience with its out-of-season tranquility.
