This beach is located at the south west tip of the Isle of Anglesey. Access is gained
via a large conifer plantation owned by Forest Enterprise. Offshore sandbanks fringe
the bathing area, which forms a relatively sheltered shallow lagoon. The bay is located
within the Newborough Warren and Llanddwyn Island National Nature Reserve. It is also
within the Anglesey Coast Salt marsh Special Area of Conservation, the Anglesey Area
of Outstanding Natural Beauty and the Newborough Warren - Ynys Llanddwyn Site of Special
Scientific Interest. The bathing water sample point is located 420 metres south west
of the main beach entrance.
Inspections are carried out by Natural Resources Wales in partnership with the local
authority and the water company. These are carried out pre-season (before the 1st
of May) and mid season, if required (during the bathing water season).
Natural Resources Wales samplers make visual observations of the beach at every visit.
This includes assessments of sewage debris, animal faeces, litter and oil or tar.
At Llanddwyn, data are available for the four year assessment period from 2011-2014.
Sewage debris was observed in trace amounts on less than ten per cent of occasions.
Trace amounts of animal faeces were noted at the site on a minority of occasions.
Trace amounts of litter were observed at the bathing water the majority of the time.
Oil and tarry residues were not noted at this site.
