Lleiniog Beach is mostly sand and shingle, and located at the top north-eastern corner of Anglesey, about 2½ miles north of Beaumaris. The beach is muddy at low tide, and has some impressive views across the Menai Straits towards the mountains of Snowdonia and Great Orme Head (in the distance, above). There is a small car park with seating and picnic tables overlooking the Strait. Further north is Penmon Beach (Grid Ref: SH629802), which has some roadside parking in lay-bys at the southern end. The photos were taken at low tide.
Places worth visiting, and within easy walking distance are Penmon Priory and St Seiriol's Well at the northern end, and the recently restored Aberlleiniog Castle a short distance back along the road to Beaumaris.
