This calm glacial valley in County Wicklow houses a 6th-century monastic settlement with a 30-meter round tower. Visitors can hike around two lakes and explore the Wicklow Mountains.
Glendalough, meaning "valley of two lakes" in Irish, is a calm glacial valley in County Wicklow. You can explore the ruins of a 6th-century monastic settlement, including a 30-meter round tower, several ancient churches, and stone crosses. The area has walking trails around two lakes, where you might spot deer and various bird species. In the visitor center, you'll learn about St. Kevin, the founder of the monastic settlement. The surrounding Wicklow Mountains offer hiking opportunities for various skill levels.
Upper and Lower Lakes
Two glacial lakes give Glendalough its name and provide a calm backdrop for walks. You'll find the Lower Lake closest to the monastic ruins, while the larger Upper Lake is about a 20-minute walk further into the valley. As you walk along the shoreline trails, you'll see the surrounding forested hills reflected in the water. Watch for wildlife like deer and various bird species in the area.
Hiking in Wicklow Mountains National Park
Glendalough sits within Wicklow Mountains National Park, offering numerous hiking options. If you're up for a challenge, try the Spinc trail, which provides extensive views over the lakes and valley. For an easier walk, take the boardwalk path to Poulanass Waterfall. At the visitor center, you can get maps of marked trails ranging from 30-minute strolls to full-day hikes. Remember to wear sturdy shoes and bring rain gear, as weather can change quickly in the mountains.
Exploring the Monastic City
The heart of Glendalough is its "Monastic City," established by St. Kevin in the 6th century. As you enter through the stone gateway, you'll see the remains of several churches dating from the 10th-12th centuries. The 30-meter round tower stands as one of the best preserved in Ireland. Look for the cathedral ruins, St. Kevin's Church with its distinctive roof, and ancient stone crosses scattered throughout the site.
Visiting Tips
Glendalough becomes crowded, especially on summer weekends. For a quieter experience, arrive early in the morning or visit midweek if possible. You can enter the monastic site year-round at no cost. The visitor center charges a small fee and provides context through exhibits and a short film. Plan to spend a full day exploring the area, so bring lunch or stop at the hotel restaurant. While public buses run from Dublin, having a car allows you to explore the wider Wicklow area more easily.
St. Kevin's Legends
St. Kevin came to Glendalough as a hermit in the 6th century, seeking solitude. Local lore says he lived in a cave above the Upper Lake, now known as "St. Kevin's Bed." Stories describe his close connection with nature - one claims he once held out his hand so long in prayer that a blackbird built a nest in it. While many tales are likely exaggerated, they reflect Kevin's reputation for holiness that drew followers and led to Glendalough's growth as a monastic center.
