The most well known area of the Comeragh mountains is Mahon Falls. The valley has an impressive waterfall surrounded by striking cliffs, and its easy access from the main Waterford to Cork road means that it is a very popular destination for day trippers and tourists.
This is the west side of the climb and toughest of the sides. Mahon Falls starts from Mahon Bridge and is approx 5 Km long with an average gradient of 7%, but the last 500m of the climb has sections of up to 15%.
