Welcome to Wicklow Mountains
The highest peak in the range, Lugnaquilla (924m), is really more of a very large hill. The vast granite intrusion, an upwelling of molten rock that solidified some 400 million years ago, was shaped during the ice ages into the schist-capped mountains visible today. The wild topography is marvellously desolate and raw. Between the mountains are a number of deep glacial valleys – most notably Glenmacnass, Glenmalure and Glendalough – and corrie lakes such as Lough Bray Upper and Lower, and Lough Tay, gouged by ice at the head of the glaciers.
