Black Lake, Glacial lake in Triglav Lakes Valley, Slovenia.
Black Lake sits at 1,319 meters (4,330 feet) elevation in a forest-ringed basin dominated by the steep Komarča rock face in the Julian Alps. The water fills a natural depression carved during the ice age and remains surrounded by high peaks on all sides.
The lake formed during the ice age when glaciers carved out the valley and left behind a deep depression. It now belongs to the chain of Triglav Lakes, a system that holds deep roots in Slovenian cultural traditions and artistic representations.
The lake's Slovenian name Črno jezero comes from the dark reflections on its water surface, created by the surrounding forest canopy above. Visitors often pause at the shoreline to observe how the water seems to absorb light rather than reflect it.
Access is via a challenging hiking path from Slap Savica, with metal supports and ropes helping on steep sections. Good footwear is recommended and allow extra time for the climb, as the ground can be slippery especially after rain.
Being the lowest-lying lake in the Triglav chain, it retains more warmth and reaches water temperatures around 9 degrees Celsius (48 degrees Fahrenheit) during summer. This makes it the more comfortable choice for visitors seeking a gentler swimming experience than at the higher lakes.
