Overview
Nestled in the heart of County Wicklow’s forested landscape, Devils Glen is a dramatic, ice‑age‑carved gorge where the Vartry River rushes from the Vartry Reservoir down to the village of Ashford. The valley is flanked by a mixed woodland of broad‑leaf and conifer trees, with notable stands of beech, Spanish chestnut and ash. The sheer rock faces are a living laboratory for lichens, mosses and the delicate polypody fern, making the glen a haven for botanists and nature lovers alike.
The site forms part of the historic Glanmore estate, once the ancestral home of playwright John Millington Synge. Across the northern bank lies the privately owned Tottenham Estate, adding a touch of aristocratic intrigue to the scenery.
History & Background
The gorge was sculpted at the close of the last Ice Age when melt‑water from the retreating ice sheet carved a deep channel through the bedrock. Over centuries, the Vartry River has continued to shape the landscape, creating the waterfall that now marks the entrance to the glen. Before the Vartry Reservoir was built in the 1860s, the waterfall’s roar was said to be so powerful that locals described it as a “Satanic power announcing some great doom,” a legend that cemented the name Devils Glen.
What to See & Do
Seamus Heaney Walk (4 km, ~2 hrs, moderate)
Named in honour of the Nobel‑prize‑winning poet, this loop winds through the high forest, offering quiet, reflective passages beneath towering trees. Interpretive signs highlight Heaney’s connection to the Wicklow woods, making the walk both a literary pilgrimage and a nature trail.
Waterfall Walk (5 km, ~2 hrs, moderate)
The Waterfall Walk leads directly to the glen’s centerpiece – the Devils Glen Waterfall. While the cascade is modest in height, its setting within the steep gorge creates a striking visual and acoustic experience. The path is well‑waymarked and provides several spots for a brief pause, a picnic, or simply to listen to the river’s murmur.
Flora & Fauna
Beyond the walks, keep an eye out for the diverse plant life that colonises the gorge’s rock faces: vibrant lichens, spongy mosses and the distinctive polypody fern. Birdwatchers may spot woodland species such as the jay, great tit and occasional woodpecker.

A short drive brings you to Mount Usher Gardens, a celebrated horticultural showcase in Ashford, perfect for extending a day of outdoor exploration.
