The most well known area of the Comeraghs is Mahon Falls. The valley does have a very impressive waterfall surrounded by striking cliffs and its easy access from the main Waterford to Cork road and its large car park means that it is a very popular destination for day trippers and tourists.
Not the biggest mountain climb. Mahon Falls starts from Mahon Bridge and is approx. 5 km long with an average gradient of 7 % BUT the last 500 m of the climb has a gradient of up to 15%.
