The SS Regolo is a technical wreck dive located off Krk Island, Croatia, resting at depths between 50 and 66 metres. This site requires trimix and advanced technical diving protocols due to the extreme depth and potential for nitrogen narcosis. Access is strictly by boat, and divers must be prepared for variable currents and potentially low visibility. The wreck structure provides a habitat for various marine life, though species recorded around this area include wrasses, scorpionfish, bream, and yellow gorgonians. Given the depth and environmental hazards, including decompression requirements, this site is suitable only for experienced technical divers using professional boat support.
