The Comeragh Mountains stretch diagonally across County Waterford from Dungarvan to Clonmel. They divide the county roughly in half. As mountains go they are not spectacularly high but they are rugged and interesting, abounding in lakes, rivers, hollows, cliffs and rocky slopes. At the very summit of the range is a great bog which gave the mountains the name Monavollagh meaning “turf on top”, but the name by which they are better known is The Comeraghs ( Na Comeraigh), meaning having many river confluences. Our objective for this Moonlit walk is the stunning Coumshingaun Lake or Com Seangan (pissmire valley also translated as hollow of the ants. Coumshingaun is perhaps the finest example of a glacial corrie or coum in the British Isles. It was formed during the last ice age by the retreating glaciers which left a large moraine at the mouth of the coum holding the lake back to what we see today.
