Sruth in Aghaidh an Aird

Sruth in Aghaidh an Aird is a waterfall in the Dartry Mountains that plunges about 150 meters from the plateau edge, creating dramatic vertical streams over limestone cliffs. The water descends into Glencar Lough below, forming a powerful display of falling water and mist.

The waterfall once marked territorial boundaries of the ancient túath of Cairbre Drom Cliabh and served as a natural dividing line in medieval Irish administration. This geographical importance connected the site to the political structures of early Irish society.

The cascade is known locally as The Devil's Chimney, and its Irish name translates to 'stream against the height'. These names reflect how the falls feature prominently in how people understand and speak about this mountain landscape.

A looped trail leads visitors through woodland paths with steps on steeper sections, so proper footwear is important for safe walking. After rain the paths become wet and slippery, so it pays to move slowly and watch your footing throughout the route.

During strong southerly winds, the water flow reverses and the waterfall flows upward against the cliff rather than falling down. This unusual phenomenon shows how powerful local wind patterns can be and creates a remarkable sight for visitors who experience it.
