About this beach

The beach is a long sandy beach extending from a curved end located to the east of Pwllheli Harbour and extends towards Pen Ychain headland to the east. The beach area abuts the Lleyn Peninsula and the Sarnau Special Area of Conservation and the Morfa Abererch Site of Special Scientific Interest, confirming its high conservation status. The water quality sample point is opposite the entrance to the beach from the car park by Plas Heli (the sailing academy).
