Glendalough Spinc Trail – A Rugged Loop Through Wicklow’s Wild Heart

Overview

The Spinc Trail is one of Wicklow’s most celebrated walking routes, offering a demanding 10.4 km loop that threads through the dramatic landscape surrounding Glendalough’s twin lakes. Rated “Very Difficult” and taking roughly four hours to complete, the trail climbs a total of 490 m and is marked with bright red way‑markers. The walk begins and ends at the National Park Information Office on the Upper Lake’s shore, just outside the picturesque village of Laragh.

History & Background

Glendalough, meaning “Valley of the Two Lakes”, has been a focal point of Irish heritage for over a millennium. The valley is famed for its early‑medieval monastic settlement founded by St Kevin in the 6th century, and the surrounding landscape is dotted with ancient stone crosses, high crosses and burial sites. While the Spinc Trail itself is a modern walking route, it traverses terrain that has witnessed centuries of pilgrimage, farming and folklore. The trail’s name derives from the Spinc, a steep ridge that offers unrivalled panoramas of the Upper Lake, linking the historic heart of Glendalough with the wilder reaches of the Glenealo Valley.

What to See & Do

The walk opens with a gentle forest path that soon gives way to a steep ascent toward the iconic Poulanass Waterfall. Here, a short boardwalk leads visitors to a crystal‑clear basin where the water plunges over smooth stone, creating a tranquil pool that reflects the surrounding woodlands. Continuing upward, a series of wooden steps guide walkers to the Spinc’s viewing platform. From this perch, the Upper Lake stretches out in a mirror‑like expanse, framed by the rugged silhouettes of Lugduff Mountain and the distant peaks of the Wicklow range.

Wildlife enthusiasts will appreciate the boardwalk section before the turn‑off for Lugduff, a prime spot for spotting deer grazing in the early morning mist, as well as birds of prey such as kestrels, merlins and ravens soaring above the ridge. The trail then sweeps under Lugduff Mountain, descending into the lush Glenealo Valley. This forest‑road segment winds through ancient oak and birch stands, offering occasional glimpses of the valley floor’s carpet of heather and wildflowers.

After completing the loop, many walkers pause in Laragh, a small but welcoming village just a short stroll from the trailhead. Here, traditional Irish pubs and cafés provide a perfect setting to unwind, share stories of the hike, and sample local fare.
