The Srnica cave

The Srnica cave is distinguished by fossilised heart-shaped mussels. In long-lasting or heavy rains, the Srnica cave fills up with water and turns into a temporary water source. A waterfall forms at the upper entrance to the cave.
There is a 63 m difference in altitude between the entrances to the cave. Exploring the Srnica cave is difficult and can only be attempted with the right equipment and an experienced guide.
The Mala Boka cave system

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.

The Cave of Zadlaška jama or Dante's Cave
The cave of Zadlaška jama, named after the village Zadlaz, is one of several caves through which the waters of the Soca glacier flowed.
This cave complex is 1.140 m long, 41 m deep and boasts three halls.
It is said that at the beginning of the 14th century, the patriarch Pagano della Torre hosted the poet Dante Alighieri in Tolmin. At that time, he is said to have visited the cave, which inspired him to create the Hell of the Divine Comedy. The cave was later named after the poet.
In 1922 it was explored and mapped for the first time by the members of the Krpelj Tourist Association and it was later made suitable for visitors - stairs have been carved in and passages deepened. It was fully explored and mapped by the Speleology section of the Tolmin Mountaineering Society in 1977.
There are two types of cave bugs living there – namely, Anophtalmus ravasnii sontiacus; Muller 1935 and Anophtalmus Tolminensis; Muller 1922, Pretnar 1970, as well as the bat, known as the Rhindolophus hipposideros.
Zadlaška jama is among the most difficult tourist caves, which is why it is only possible to visit it in the company of a competent guide and with appropriate equipment.
