The Triglav Lakes Valley is a rocky hanging valley in the Julian Alps in Slovenia, below the sheer sides of Mount Tičarica and Mount Zelnarica southwest of Triglav. The valley is also called the Seven Lakes Valley, although there are ten and not seven lakes in the valley. It is above the tree line and is geologically alpine karst; therefore it has also been termed the Sea of Stone Valley.
The lowest lake is Black Lake at an elevation of 1,294 metres (4,245 ft) above sea level; it is above the rocky slope of the Komarča rock face. The Alpine newt (Ichthyosaura alpestris), endemic to the Alps, lives in it. Below Mount Tičarica (elevation 1,676 m (5,499 ft)) there are two interconnected lakes known as Double Lake (Dvojno jezero). At an elevation of 1,838 m (6,030 ft) lies Big Lake or Ledvica Lake. This is the largest and the deepest of these lakes. The highest is Podstenje Lake, which is located at an elevation of 1,993 m (6,539 ft).
There are two mountain huts in the Triglav Lakes Valley. The Triglav Lakes Lodge (Koča pri Triglavskih jezerih; 1,683 metres or 5,522 feet), owned by the Ljubljana–Matica Mountaineering Club, is located at its southern edge, whereas the Central Sava Lodge at Prehodavci (Zasavska koča na Prehodavcih; 2,071 metres or 6,795 feet), owned by the Radeče Mountaineering Club, is located at its northern edge. They are two hours apart. They may be accessed from Bohinj over the Komna Plateau (5 hours to the Triglav Lakes Lodge), from Bohinj over Komarča Crag (3 hours), from Blato Mountain (3:30 hours), from Trenta (3 hours to the Central Sava Valley Lodge, and over Trebiščina Mountain Pasture (3:30 hours to the Central Sava Valley Lodge).
