The Mala Boka cave system
This cave system is 1319 m deep and 8168 m long.
Possibly one of the deepest cave systems in the world, Mala Boka has been attracting countless experienced cavers for over 30 years now.
The entrance is situated at the Boka waterfall at an altitude of 450 m. The average temperature in the cave is 8 ºC. A small section of the cave system is open for guided caving tours, organised by several Bovec sports companies. The locals know it as the Golobja cave. The large entrance hall measures 35 x 12 m.
When it rains, the dry and silent tunnels of Mala Boka, the cave halls and the stalagmite and stalactite displays are filled with wild waterfalls and torrents.
