Glendalough Nature Reserve is a historic and ecologically rich area famed for its scenic valleys, ancient monastic ruins, and diverse hiking trails set in the Wicklow Mountains.
Glendalough Nature Reserve is located in County Wicklow, Ireland, within the Wicklow Mountains National Park. It spans a glacial valley carved by ice, featuring two clear freshwater lakes surrounded by steep-sided hills and dense woodland.

Ruins such as the round tower, stone churches, and crosses highlight its significant place in Irish history. The diverse landscape supports a variety of habitats, including oak and birch woodlands, heathland, and wetlands, which provide a home to numerous bird species, red squirrels, and native flora. Glendalough offers visitors a range of hiking opportunities from short lakeside walks to challenging ridge routes like the Spinc, which offers panoramic views of the valley and lakes below. This area is a prime destination for outdoor enthusiasts interested in history, wildlife watching, photography, and nature appreciation. The combination of rugged terrain, ancient stonework, and tranquil waters creates a compelling destination for visitors year-round.
