St Kevin's early medieval monastic site and two glacial lakes in the Wicklow Mountains
Glendalough, the valley of the two lakes, is where heritage and nature meet. A slender round tower rises above a graveyard of weathered crosses and headstones, small stone churches sit among the trees, and beyond them the valley opens out to the Lower and Upper Lakes framed by steep wooded mountainsides.
It lies within Wicklow Mountains National Park, south of Dublin, which makes it a favourite day trip from the capital. Visitors can explore the monastic city, learn its story at the visitor centre and then follow waymarked trails along the lakeshore or up onto the ridges for sweeping views down the valley.
In the sixth century St Kevin, one of Ireland's most revered saints, came to this glaciated valley seeking solitude and founded a monastery. Tradition holds that he died in about 618. Over the following centuries the settlement grew into one of the most famous religious centres in Europe, attracting monks, students and pilgrims.
The surviving remains include a round tower about 30 metres high, a ruined cathedral built in several phases, several medieval stone churches and decorated crosses. St Kevin's Church, nicknamed St Kevin's Kitchen because its little belfry resembles a chimney, is one of the most recognisable buildings. The settlement was plundered more than once, and in 1398 English forces left it in ruins, yet it remained a place of local worship and pilgrimage. Above the Upper Lake, a small man-made cave known as St Kevin's Bed is traditionally linked to the saint, though it may be an older prehistoric burial place.
Glendalough has been a place of pilgrimage for well over a thousand years, and it still holds deep spiritual meaning for many Irish people, while the surrounding mountains are a weekend playground for Dublin walkers and climbers. The nearby village of Laragh is the local hub. Visitors of all faiths are welcome at the monastic site; please treat the graveyard, which is still a place of remembrance, with quiet respect.
Begin at the Glendalough Visitor Centre, run by the Office of Public Works, for an exhibition on the monastic settlement, then walk through the gateway into the monastic city to see the round tower, cathedral and St Kevin's Church. From there, paths lead through woodland past the Lower Lake to the Upper Lake.
Keen walkers can tackle the Spinc and Wicklow Way loop, an 11 km route with lake views, woodland and a waterfall, or follow part of St Kevin's Way, a 34.3 km pilgrim path across the mountains. Look out for peregrine falcons overhead. Guided tours of the monastic site are available on request.
Late spring to early autumn offers the longest days and the best conditions for walking, with fresh green woodland in May and June and heather on the hillsides in late summer. Summer weekends and bank holidays bring crowds and busy car parks, so arrive early. Autumn colours in October are beautiful, and winter visits are peaceful, though paths can be muddy and daylight is short.
