Ogof Dydd Byraf

Ogof Dydd Byraf is a cave beneath Esclusham Mountain in north-east Wales. Its entrance lies on the south face of the Minera Limeworks quarry. The Wrexham Caving Club first found and explored the cave in 1964. Later it became part of the North Wales Caving Club. The cave runs under ground for a long distance from this single opening. The cave holds a narrow shaft ten metres deep that leads to decorated chambers. Some passages run close to another cave, Ogof Llyn Du, but its entrance is blocked by a deep sump. Quarry work once threatened the cave’s existence. Today it is protected as a Site of Special Scientific Interest and belongs to the North Wales Wildlife Trust. Visitors walk through short mined passages before reaching the shaft. Well-decorated galleries open up beyond the drop. The cave’s walls show natural cave formations. Nearby Ogof Llyn Du remains out of reach because of the blocked passage. The protected status keeps the cave safe for future explorers.
