Dive-site story
Portroe Dive Quarry is a flooded slate quarry in County Tipperary that serves as Ireland's premier inland training and recreation center. Sheer rock faces drop down to submerged slate working platforms, underwater training grids, and various sunken attractions including cars, boats, and a submerged van. The sheltered nature of the quarry allows year-round diving when sea conditions on the coast are unworkable.
Sunken vehicles and boats arranged as navigation and penetration courses
Sheer slate quarry walls providing clear reference points for deep and technical training
Submerged training platforms and suspended swim-throughs for buoyancy practice
Resident freshwater fish including introduced sturgeon and brown trout
