About this site
Portroe Dive Quarry is an inland dive site in North Tipperary, Ireland, near the village of Portroe on the western side of Lough Derg. The area sits in a former slate quarrying district in the hills above the lake, and the flooded quarry workings reach a maximum depth of around 40 metres, making this a site rated advanced rather than a typical training quarry.
