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.
