'''Dulas Bay''' ({{lang|cy|Bae Dulas}}) is a small bay on the northeast coast of [[Anglesey]] ({{getmapecho|SH490889}}).  The bay is bordered by three beaches.

==Overview==
The north-western beach is the sand/shingle/mud estuary Traeth Dulas (''Dulas Beach''); southeast of this is the tiny Traeth Bach (''Small Beach'') and the sandy Traeth Yr Ora (''Beach of The Fortified Landing Place'').

The estuary running through Traeth Dulas is that of the Afon Goch (''Red River''). The Traeth Bach and Traeth Yr Ora at high tide are separated by a rock outcrop called Craig y Sais (''The Englishman's Rock''). At low tide, however, it is possible to walk on the sand between the three beaches and also onto th beaches of [[Lligwy Bay]] to the south. Traeth Dulas is most affected by the tide, so much so that the most inland parts of the estuary are salt marshes.

A walk is the circuit starting at [[Lligwy Bay]], taking in Traeth Ora, the Pilot boat Pub and an option to reach the top of nearby Mynydd Bodafon.

About a mile and a half off shore is a small island, [[Ynys Dulas]], which is roughly 680 yards long and has a maximum width of 225 yards. It is known for the seals which live on the island<ref>[http://www.ccw.gov.uk/generalinfo/index.cfm?Action=View&RID=143&subject=Marine CCW report on seals in North Wales]</ref> (from which it is also known locally as Seal Island), but it is too small for human habitation. However, upon this island is a round structure with a cone-shaped top that was built in 1924 by Lady Dorina Neave to store food and provide shelter for shipwrecked seamen.<ref>[http://test.photographers-resource.com/locations/Routes/Islands/LG/Anglesey/Anglesey.htm Anglesey on Photographers Resource]</ref>

Two significantly smaller islands, Garreg Allan (''The Outer, Expelled or Furthest Stone'', not visible by the naked eye from the shore, behind Ynys Dulas) and Ynys y Carcharorion (''Prisoners' Island'', nearer Traeth Dulas) are also present. Oil tankers can often be seen out some miles from shore in the [[Irish Sea]], as they wait for the tide to enter the River Mersey for discharge at Tranmere Oil Terminal.

==Bathymetry and history==
[[File:Traethdulas.jpg|right|thumb|240px|Traeth Dulas, the estuary of Afon Goch]]
The bathymetry of the bay is interesting. No water less than a mile out is over sixty-five feet deep. The most steep decline in the sea bed is found out from Traeth yr Ora. Conversely, a raised shelf of seabed about a mile long reaches out just beyond Garreg Allen, none of which is over 15 feet deep. This is followed by a drop to much deeper water (over 65 feet deep), which indicates that Ynys Dulas may have been part of what is, geologically speaking, a recently submerged headland.

On the north side of Traeth Dulas stands Porto Bello, an interesting house built very much in the Mediterranean style. On top of the cliffs just south of Traeth yr Ora, overlooking the [[Irish Sea]], is a concrete observation post left over from Second World War. Slightly north of the bay is the village of Llysdulas. It was here that the manor house ''Llys Dulas'' (''Dulas Manor" or "Court'') was located, and the families who owned the bay lived here. The land passed through the Neave and Hughes families. Under the ownership of Lord Boston, however, the mansion fell into disuse and no longer exists. Some ruins of the chapel can still be found.

Traeth yr Ora and Porto Bello were, according to local history, apparently named after a group of men allegedly shipwrecked in the area around 1750. The men were said to be of Spanish or Portuguese origin, but the precise spelling of these names suggests that the men may actually have been Italian. Some local families still claim descent from these men today.

Perhaps the oldest known tradition regarding the bay dates from 1134. It is said that Owain Gwynedd, who became king of [[Gwynedd]] in 1137, had defeated a combined force of the Irish, Manx, and Norsemen near [[Llangwyllog]] in the centre of the island. The Welsh fleet turned on their enemy's ships and are said to have captured every last one of them in and around Dulas Bay.<ref>{{genuki|Llangwyllog}} - The Bay described on the page about Llangwyllog</ref>

The bay is on the [[Anglesey Coastal Path]] and has, with most of the rest of the coast of Anglesey, been designated as an Area of Outstanding Natural Beauty by the UK government. The geological makeup of the area is mostly Devonian Old Red Sandstone, although the north side of Traeth Dulas sees the limestone beds alternating with shale and gritstone. There are unusual levels of zinc and copper in the soil, and a water-table brought in by Afon Goch from mines in nearby [[Parys Mountain]].<ref>[http://www.ingentaconnect.com/content/klu/egah/2003/00000025/00000001/05095105 Academic report on metals in Dulas Bay]</ref> However, the level is nowhere near high enough to be of danger to health.<ref>[http://journals.cambridge.org/action/displayAbstract;jsessionid=3B965741BE8680C43BC594239B5695F0.tomcat1?fromPage=online&aid=137097 Cambridge Journal article on metal levels]</ref>

Just two and a half miles from the bay is [[Mynydd Bodafon]], the highest point on the Isle of Anglesey, reaching 584 feet above sea level.

The bay is reached by turning right off the A5025 at [[Brynrefail]] and although the three beaches are in the parish of Moelfre, Ynys Dulas is under the control of the Llaneilian parish council. Other nearby villages include [[Moelfre]], [[Benllech]] and Dulas. There are several good quality camp sites within a few minutes' walk of the beaches.
