{{langnf|cy|'''Ynys Dulas'''|'''Dulas Island'''|italic=no}} is a small island located off the north-east coast of [[Anglesey]] ({{langx|cy|link=no|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 [[Dulas Bay]]. The size of the island depends on the [[tide]], with a maximum length of 623 metres and width of 207 metres against a minimum of 184 metres by 35 metres. It has a maximum area of {{convert|18.3|acre|m2}}. The island is mainly rocky, but at low tide sand is exposed, most noticeably on the southern part of the island where it separates the main rock formation from two smaller ones named Garnog ('<nowiki/>''Hooves'<nowiki/>''). [[pinniped|Seals]] are often spotted living on and around the island,<ref>[http://www.ccw.gov.uk/generalinfo/index.cfm?Action=View&RID=143&subject=Marine CCW report on seals in North Wales] {{webarchive|url=https://web.archive.org/web/20060426221539/http://www.ccw.gov.uk/generalinfo/index.cfm?Action=View&RID=143&subject=Marine |date=2006-04-26 }}</ref> but it is too small for human inhabitation. There is also very little [[flora]] on the island owing to its rocky composition. However, on lower lying parts of the island, exposed at low tide, [[seaweeds]] and other sea plants live. A smaller rock called Garreg Allan ('<nowiki/>''The Outer, Expelled or Furthest Stone''') is found about 100 m behind the island, but is not visible with the naked eye from the shore.

A raised shelf of seabed about 1.5&nbsp;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.<ref>[http://www.magic.gov.uk/website/magic/viewer.htm?startTopic=magadminareas&xygridref=248000,386800&Title=Brynrefail&startScale=5000 Bathymetric Map of Dulas Bay showing raised shelf reaching to Ynys Dulas]</ref> 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.<ref>[https://www.youtube.com/watch?v=wrq977sG59M Video on the island showing the stone giving the date of the tower]</ref> A map drawn up in September 1748 by [[Lewis Morris (1701-1765)|Lewis Morris]] shows the island named as Ynys Gadarn ('''Strong or Mighty Island''') not Ynys Dulas.<ref>[http://www.llgc.org.uk/lem/lem006.htm A copy of Morris' map]</ref>

== Sinking of ''Mary Ann'' ==
On 16 November 1928 ''Mary Ann'', a {{GRT|138}} 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, Cornwall|Falmouth]]  with a cargo of coal, when it was stranded on Ynys Dulas.<ref>{{Coflein|num=272208|desc=Mary Ann|language=en|access-date=2018-09-10}}</ref>
