The Triglav Lakes Valley (Slovene: Dolina Triglavskih jezer) is a rocky hanging valley in the Julian Alps in Slovenia, below the sheer sides of Mount Tičarica and Mount Zelnarica southwest of Triglav.
It is above the tree line and is geologically alpine karst; therefore it has also been termed the Sea of Stone Valley (Dolina kamnitega morja).
The Alpine newt (Ichthyosaura alpestris), endemic to the Alps, lives in it.
The highest is the Podstenje Lake (Jezero v Podstenju), which is located at an elevation of 1,993 m (6,539 ft).
The Triglav Lakes Lodge (Koča pri Triglavskih jezerih; 1,683 metres or 5,522 feet), owned by the Ljubljana-Matica Hilwalking 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), operated by the Radeče Alpine Club, is located at its northern edge.
