Name Mahon Falls County Waterford Nearest Town Kilmacthomas Access Road N25 About The River Mahon flows from the Comeragh Mountains in County Waterford and gathers force to create the Mahon Falls, a tall cascade on the Mahon River that empties from a mountain lake overlooking the southern coast.

Located off the N25 at Leamybrien, the Falls are located 20 kilometres from Waterford City.

The cascade runs down the centre of a high and wide valley, populated with many types of vegetation, jutting rocks, and herds of domestic sheep and goats.

It is deceivingly tall, and the valley deceivingly wide.

Mahon Falls can only be approached by car and accessed on foot.

Falling down the 80-metre Mahon Falls and proceeding past the “Fairy Bush”, the river then passes through the village of Mahon Bridge and on past Flahavans Mill and under the 8-arched rail bridge in Kilmacthomas.

Finally ending its journey at Bunmahon (literally “the bottom of the Mahon”) on Ireland’s south coast, the river drains into the region of the Atlantic Ocean known as the Celtic Sea.
