Get ready for a truly magical walk to Sruth in Aghaidh an Aird, which you might hear called the Devil's Chimney. It’s home to Ireland's tallest waterfall, and if you time your visit after a good rain, you're in for a treat. The trail itself is a lovely 2.5km loop that takes about an hour, climbing up through peaceful woodland with stunning views over Glencar Lough. On a windy day, you might even see the famous sight of the water blowing straight back up the cliff face. It's a bit of a steep climb in places, but the path is well-kept and the view from the base of the falls is absolutely worth the effort.
