The Derry Girls actress abandons her electric bike for a hydrobike to explore the island town of Enniskillen. She descends underground to experience the caves of a National Geopark, steps closer to heaven on the Cuilcagh Mountain Boardwalk, goes native at the Beaghmore Stone Circles, discovers the ancient monuments of Lough Erne, and meets a man about a sheepdog in the spectacular Sperrins.
