Glen Head

Overview

Glen Head marks the westernmost tip of the Glencolmcille valley in County Donegal. This dramatic headland protects a landscape rich in early Christian heritage and prehistoric archaeology, while offering one of the most compelling coastal walks on the Wild Atlantic Way. The route takes you past a Napoleonic watchtower and along the shattered quartzite cliffs of Sturrall, where the Atlantic Ocean crashes against ancient rock formations.

The Coastal Walk

Described by The Irish Times as “possibly the nicest coastal walk in Ireland,” the Glen Head trail is a short but enthralling route that rewards those willing to embrace the elements. The walk begins at Beefan, roughly 1.5 km from the village of Glencolmcille. You’ll pass the stone Napoleonic Watchtower, a reminder of the defensive structures once built along the Donegal coast to guard against invasion.

From the watchtower, the path leads toward the headland’s crowning feature: the Sturrall sea-arête. This jagged ridge of quartzite has been battered by centuries of Atlantic storms, creating a dramatic landscape of undercut sea arches, surf-girdled stacks, and deep stream-cut ravines. The terrain is rugged and authentic; there are no manicured paths here, just cropped grass and rocky outcrops.

The route continues along the wild shore until you reach the village of Port. The final stretch often brings you close to a memorial stone dedicated to the 19 crew members of the ship Sydney, which was lost off this coast in November 1870. The walk covers approximately 5 km with 220 m of ascent, taking about three hours at a leisurely pace. While rated easy to moderate, walkers should exercise caution on off-trail sections near cliff edges, particularly when the wind picks up or the ground is wet.

History & The Turas Pilgrimage

The valley sheltered by Glen Head is named after Saint Colmcille (Saint Columba), one of Ireland’s three patron saints. Born in Donegal around AD 521, Colmcille later founded the monastery on Iona, playing a pivotal role in spreading Christianity across northern Britain. His connection to this specific valley is documented in the 16th-century Life of Colum Cille by Manus O’Donnell.

Every year on Colmcille’s feast day, 9 June, the Turas Glencolmcille takes place. Pilgrims and walkers visit fifteen penitential stations scattered across the valley. These stations blend early Christian devotion with much older prehistoric sites. The first station, for example, is a modified megalithic tomb, showing how Christian rituals were layered onto sacred Neolithic spaces.

One of the most famous stations lies in Baile na nDeamhan (the Village of the Demons). According to legend, this valley was once haunted by evil spirits that St Patrick had driven out of Croagh Patrick in County Mayo. The demons cloaked the area in thick mist and turned the river into a fiery stream. Colmcille gathered a band of saints to cleanse the valley, hurling a spear into the mist and commanding the demons to flee into the sea, where they were transformed into red, one-eyed fish. Today, the area remains a powerful reminder of the folklore that permeates the Irish landscape.

Practical Information

Getting There & Local Amenities

The trailhead is accessible via the L5055 road running through Glencolmcille. Ample parking is available in Glencolmcille village near the Fire Station / Ionad Siúil, which serves as the trailhead for the walking loops. The watchtower itself is only accessible on foot via a steep climb. If you are travelling without a car, the Local Link Donegal Route 293 operates between Donegal Town and Glencolmcille. Alight at the Cashel National School stop, which is a short walk from the start point at Beefan.

After your walk, Glencolmcille offers a modest but authentic range of facilities. The village is a designated Gaeltacht area and home to Oideas Gael, a centre for Irish language and cultural courses. Visitors can find a petrol station, grocery shop, and post office, along with traditional pubs like Roarty’s and Biddy’s, where fiddle sessions are common. Several cafés and restaurants serve local food, providing a warm refuge after braving the Atlantic winds on the headland.

For those interested in the deeper archaeological history of the area, detailed maps of the Turas stations are available through heritage organisations. Timing your visit for early June allows you to witness the living tradition of the pilgrimage, while visiting in the shoulder seasons offers solitude on the cliffs as the mist rolls in over Sturrall.
