About this beach
The bay is situated on the north Wales coastline, to the east of Rhos Point, approximately 10 kilometres from the Great Orme headland. The beach is long and sandy, with a concrete promenade to the rear. The sample point is located to the left/west of the building at Porth Eirias carpark and down the beach. The sample is taken 250 meter to the left of the stones - half way between Porth Eirias Centre and the pier.
