Lake Krn (Krnsko jezero) (TILOS / no diving)
Diving is prohibited. Lake Krn, Slovenia's largest high-alpine lake at almost 1,400 m, is in the first protection zone of Triglav National Park, where ZTNP-1 Art. 15(1)(17) bans swimming, diving and boating; the park's 2012 letter names it among sites where diving breaks park rules. The atlas sheet describes a lake about 400 m long and over 16 m deep, with sunken trees, First World War iron, lush plants and introduced small fish – it is listed here only as a no-dive site.
depth: 0–16 m
