Ynys Llanddwyn, Tidal island in Isle of Anglesey, Wales.
Ynys Llanddwyn extends from Newborough Beach with sand dunes, rock formations, and two lighthouses marking its northern edge along the Welsh coast.
The island contains ruins of a church dating from the 16th century, built on the site of St Dwynwen's 5th-century monastery.
Welsh people celebrate St Dwynwen's Day on January 25th, exchanging cards and flowers in honor of the patron saint of love who lived on this island.
Visitors need to check tide times before exploring the island, as rising waters can temporarily cut off access to the mainland for several hours.
The International Union of Geological Sciences designated this location among its 100 geological heritage sites due to its late Neoproterozoic-Cambrian formations.
