Wales' 'Red Mountain': Mynydd Rhuddlan (Rhyd-y-Groes)

Yes. Mynydd Rhuddlan (also called Rhyd-y-Groes, literally "Red Mountain") is the highest point of the Clwyd Range, located north of Ruthin in Denbighshire, north-east Wales. It should not be confused with Mynydd Rhos-y-gwaliau (also called Rhyd-y-Groes), the highest hill of the Flintshire Range.
