Sarn Badrig facts for kids
Sarn Badrig, also known as Sarn Padrig, is a long, natural ridge found under the sea in Cardigan Bay, off the west coast of Wales. Its name comes from the Welsh language and means 'St. Patrick's causeway'. It is one of several similar ridges in the area.
These underwater ridges are made of rocks and gravel. They were left behind by huge sheets of ice. This happened when the ice melted at the end of the last ice age.
What is Sarn Badrig?
Sarn Badrig is the longest of these underwater ridges. It stretches for about 20 kilometers (about 12 miles). It starts near Mochras Point, which is close to Harlech. From there, it goes southwest, running alongside the Llŷn Peninsula.
You can sometimes see parts of Sarn Badrig. This happens when the tide is very low. Because it is hidden under the water, it can be dangerous for ships. They need to be careful not to hit it.
