Ynys Dulas (Welsh for 'Dulas Island') is a small island located off the north-east coast of Anglesey (Welsh: Ynys Môn), Wales. It marks the most eastern part of the parish of Llaneilian.
The island is situated about a mile and a half offshore, within

A raised shelf of seabed about 1.5 km long reaches out a little beyond Garreg Allan, meaning that the sea around it is no more than 5 metres deep. This is followed by a drop to water much deeper (over 20 metres deep), which indicates that Ynys Dulas may have been part of a recently (geologically speaking) submerged headland.[2] The island also marks the termination of an old limestone headland which geologically separated Dulas Bay from Lligwy Bay and Red Wharf Bay.
The island has a rescue tower that once stored food and provided shelter for shipwrecked seamen. The cylindrical, stone-cone-shaped structure was completed in 1824 by Colonel James Hughes of Llys Dulas Manor.
Sinking of Mary Ann
On 16 November 1928 Mary Ann, a 138 GRT wooden brigantine built in 1879 by Kingston of Moray, registered in Guernsey and owned by George H Grounds of Runcorn, was sailing from Runcorn to Falmouth with a cargo of coal, when it was stranded on Ynys Dulas.[5]
