Abisso di Lamar, Natural cave system in Vallelaghi, Italy.
The Abisso di Lamar is a cave system in the Vallelaghi region with several vertical shafts and narrow passages descending about 385 meters below the surface. The network contains interconnected chambers and passages that continue to be explored and documented by researchers.
In the 1970s, the Vigolo Vattaro cave group discovered new sections through windows along the Trieste shaft. These discoveries significantly expanded the known layout of the system.
Speleologists and researchers from the region regularly explore this cave to understand the geological features of the Alpine underground. The site holds importance for the local community as a focus of scientific study and nature discovery.
The entrance sits about 30 meters above the eastern shore of Lake Lamar and requires specialized climbing equipment to explore. Only experienced cavers with advanced technical skills should attempt this site, as the narrow passages and vertical shafts demand proper training.
Inside the cave lies the Trieste shaft, an impressive vertical section that descends straight down through the rock. This particular shaft is notable among cavers for its consistent width and remarkable vertical drop.
