Glendalough, located in County Wicklow, is one of Ireland’s most historically significant and visually striking valleys. It’s best known for its early medieval monastic site, founded by St. Kevin in the 6th century. The round tower, cathedral ruins, and stone churches that remain today are surrounded by forests, lakes, and mountain trails, creating a setting that feels both ancient and untouched. Many of the original paths still guide pilgrims and hikers to this day, making it a place where history and daily life quietly overlap.

The name Glendalough means “Valley of the Two Lakes,” referring to the Upper and Lower Lakes nestled between steep glacial cliffs. The Upper Lake trail leads to the ruins of St. Kevin’s Cell and St. Kevin’s Bed, where the saint is believed to have lived in solitude in narrow, stone-cut shelters built into the rock. The nearby Poulanass Waterfall is easy to reach and often missed, even though its shaded, moss-covered cascades make it one of the most peaceful spots in the area.
