Črno jezero (Triglav Lakes Valley) (TILOS / no diving)
Diving is prohibited. Črno jezero lies in the first protection zone of Triglav National Park, where the Triglav National Park Act (ZTNP-1, Art. 15(1)(17)) bans swimming, diving and boating on lakes and watercourses, and the park's 2012 letter allows diving only in Lake Bohinj and the Soča at Kršovec. The PAS sheet describes the lowest and most accessible of the Seven Triglav Lakes: about 150 × 80 m, with a flat silty floor at 5–6 m and two sinkholes in the west that narrow at 8.5 m and continue underground. Newts live all over the lake, and a vertical south-west wall shades the water in the afternoon. The entry is kept here for reference only.
depth: 0–8.5 m
