Carmel Head/Trwyn y Gader
The navigation markers.

The three markers with the faint outline of a deep sea vessel above West Mouse. 


Carmel Head/Trwyn y Gader lies at the extreme north west tip of Wales on the Isle of Anglesey.  Offshore are The Skerries/Ynysoedd y Moelrhoniaid guarded by a lighthouse, while to the east of them is Maen y Bugael/West Mouse.  This is one of three small islands - East/Ynys Amlwch, Middle/Ynys Badrig and West/Maen y Bugael off the north  coast.

  On the mainland opposite West Mouse are two large triangular stone towers erected by the Mersey Docks and Harbour Board in the 1860's as an aid to navigation on this dangerous coastline.  The two towers line up with a third marker on West Mouse.  

These navigation marks are the Coal Rock Beacons, known colloquially as the White Ladies.  The sight-line through them and the West Mouse Beacon aligns with the dangerous Coal Rock, which is awash at low water spring tides.  This lies a little further offshore beyond the Mouse.  Coal Rock is the centremost of a group of three - Ethel Rock to the west and Archdeacon Rock to the east.  Coal Rock is a hazard to navigation as it lies sufficiently far offshore (one and a half miles ) to constitute a danger to vessels making a passage to or from the Point Lynas/Amlwch direction and passing outside ( to the north of ) the Skerries.  This was particularly so in the days of sail when coastal traffic was intense and the need to tack against adverse winds made diversion from a direct course necessary.  

In addition to the beacons Trinity House marked the three rocks mentioned each with its own buoy (black conical ) and at night the Skerries Lighthouse shone a red sector over the area warning of the danger.  The beacons were last painted in 1955 when a party was put ashore by the Trinity House Vessel "Argus", which used to be based in Holyhead.  Many thanks to Norman Sheldrick for much of the above information. 

 Any practical use of the towers would have been very many years ago but they remain in excellent condition.  Today's commercial shipping keeps well clear of this coastline, with its fast currents and notorious rocks although yachts and fishing boats are a common sight.  Further details on the history of this site are most welcome, please contact me here.

Carmel Head is a beautiful area of rocky coastline and is accessed by the Anglesey Coastal Path and from other footpaths in the area.  As there is little shelter and no habitation on this coastline the weather forecast should be checked before starting out  Stout footwear and appropriate clothing are also recommended.

These sheep give an idea of the size of the markers which is about 45 feet.


Carmel Head was also the site of a small copper works, the chimney of which is shown here.
