10) Coum Mahon (Com Machan), S314080.
It is an easy walk from the car park along the path that meanders across a raised plateau above the valley through which the Mahon River (An Mhachain) flows. Mahon Falls is the main attraction of the coum. During full flows the falls are truly spectacular as they rage violently, drenching the surrounding boulders. The flora is not as good as in any of the other coums of the Comeragh Mountains. In spring the north facing wall is often ablaze with yellow Primroses. Wilson’s Filmy-fern also grows on this wall as does Fir Clubmoss, Great Wood-rush and a lone Pedunculate Oak.
