Overview
Lugduff (Irish: An Log Dubh, meaning “the black hollow”) stands at 653.2 m, making it the 154th‑highest summit on the Arderin list and the 186th on the Vandeleur‑Lynam scale. Nestled in the southern sector of the Wicklow Mountains, the peak forms part of a broad horseshoe that embraces the Upper Lake of the Glendalough valley. Its steep western slopes are instantly recognisable for a distinctive “corrugated” profile that plunges into the deep side‑wall of Glenmalure, while the eastern flank overlooks the hanging valley of Fraughan Rock Glen.
History and Landscape
The mountain’s name, An Log Dubh, reflects the dark, hollow‑like character of its upper reaches, a feature that has long attracted hill‑walkers and peak‑baggers. Lugduff sits on the boundary of several classic Wicklow ranges – Mullacor, Conavalla, Camaderry and the hydro‑electric station at Turlough Hill – creating a dramatic backdrop for the valley below. Its geology is typical of the Wicklow range: ancient granite intrusions sculpted by glacial erosion, leaving the corrugated ridgeline that defines the western aspect.
What to See & Do
- The Spinc White Trail – An 8‑kilometre boardwalk that loops around the Upper Lake of Glendalough, the trail skirts just below Lugduff’s summit. Hikers follow a series of wooden walkways, including a section of roughly 600 steps that climb steeply past the Poulanass Waterfall before reaching a viewing platform. From there the boardwalk continues for about 1.7 km before veering toward Lugduff, offering panoramic vistas of the lake, the surrounding peaks and the iconic corrugated ridge.
- Summit Views – Reaching Lugduff’s summit rewards walkers with sweeping sights of the Glenmalure valley, the Fraughan Rock Glen junction, and, on clear days, the distant silhouette of Lugnaquilla, Wicklow’s highest mountain. The western wall provides a dramatic perspective of the deep glacial trough that carves the landscape.
- Nearby Attractions – The area is a hub for further exploration. Just a short drive or walk away lie Glenmacnass Waterfall, the towering peak of Lugnaquilla, the rugged mass of Scarr, and the rounded summit of Tonelagee. All are accessible via the extensive network of Wicklow Way and subsidiary trails.
Practical Information
Lugduff is situated within Wicklow Mountains National Park, and access is free of charge. The most popular starting point is the Glendalough car park (address: Wicklow Mountains National Park, Ireland), where ample parking is available at no cost. From the car park, walkers can join the Spinc White Trail or connect to the Wicklow Way for longer treks. The boardwalk is well‑maintained, but sections of the mountain’s western slopes are steep and may be boggy after rain; sturdy boots are advisable.

The summit is marked by a cairn and a modest trig point. While there is no formal visitor centre, the nearby Glendalough Visitor Centre provides maps and information on trail conditions. For detailed route data, the MountainViews database (https://mountainviews.ie) is a useful resource.
Getting There – The nearest major town is Wicklow, about 20 km north, with regular bus services (e.g., Bus Éireann route 133) to Glendalough. Private car access follows the R756 from the N11, turning onto the Glendalough Road (R755). The nearest railway stations are in Bray and Wicklow, each offering onward bus connections.
Seasonal Notes – The Spinc boardwalk is open year‑round, but winter weather can make the higher sections of Lugduff’s western slopes icy. The trail is popular throughout the year, so early‑morning visits may provide a quieter experience.
Safety – The mountain is classified as a moderate‑to‑hard hill‑walk. Navigation skills are recommended, especially when deviating from the boardwalk onto the open summit ridge. Mobile reception can be patchy; a physical map or downloaded GPS track is advisable.
Guided Walks & Events
The National Park Service runs a free Dawn‑Chorus Guided Walk in the spring and early summer, departing from the Glendalough car park and taking participants along the lower slopes of Lugduff. The walk highlights the rich birdlife of the glacial valleys and offers an early‑morning perspective of the corrugated ridge. Check the Wicklow Mountains National Park website or the Glendalough Visitor Centre for the latest dates and booking information.
