Glengesh Pass

Glengesh Pass is a narrow mountain road that climbs to 300 metres through the Slieve Tooey range in southwest Donegal, connecting the tweed town of Ardara with the remote Glencolmcille valley on the far side. The road is single-track in places and the scenery is raw — blanket bog, bare rock, and the Atlantic visible behind as the road climbs west. At the summit the view opens suddenly: the valley floor below, the glen descending toward the coast, and in clear conditions the outline of Slieve League to the south.

The descent on the western side is a series of hairpin bends into the valley floor, giving the pass a genuine drama that few mountain roads in Ireland can match. The road is perfectly driveable in a standard car, but requires care and a willingness to reverse into passing places when meeting oncoming traffic. Allow 20 minutes for the transit, more if you stop at the viewpoint near the summit.

Glengesh Pass sits naturally on the route between Ardara (known for traditional Donegal tweed weaving) and Glencolmcille Folk Village. The combination of the pass drive, the folk village, and the sea stacks at Glencolmcille bay makes for one of the most complete half-days in Donegal.
