Ynys Llanddwyn or Llanddwyn Island is a small tidal island
off the west coast of Anglesey. The island forms part of the National Nature
Reserve of Newborough Warren which includes the extensive and floristically
rich sand dune system.
Llanddwyn Island is a tidal island, but remains attached to the mainland at all but the highest tides.
The island is very rich in legends, and in particular the
association with Dwynwen. The name Llanddwyn means ‘The church of St. Dwynwen’.
Dwynwen is the Welsh patron saint of lovers, making her the Welsh equivalent of
St Valentine. Her Saint's day is 25 January and is often celebrated by the
Welsh with cards and flowers.
There are more than 10 miles of footpaths crossing Llanddwyn Island and Newborough Warren, including the Anglesey Coastal Path, and it is a very popular place to visit. The island provides a worth-while goal after the mile-long walk along the beach from the nearest car park.
