The Devil’s Glen boasts a dramatic landscape that was fashioned at the end of the Ice Age when the melt waters of the ice sheet created the valley. The resultant gorge affords a swift decent for the Vartry River as it makes its way from the Vartry Reservoir to nearby Ashford village. The site hosts a mixture of broad leaf and conifer forest with fine stands of beech, Spanish chestnut and ash. The steep rock face of the gorge has been colonised by various species of plant life: lichens, mosses and the polypody fern.
The site was once part of the Glanmore estate, former ancestral home of John Millington Synge. On the northern bank of the river you can see the privately owned Tottenham Estate.
