Tolmin Gorges

Find on the map

The Tolmin gorges are the lowest and southernmost entry point into the Triglav National Park and Tolmin’s most important sight of nature.

Tourist tracks in this area - along the Tolminka river up to the thermal spring and along the Zadlaščica river up to the Bear’s Head – were made and maintained by the Tolmin Tourist Association between 1953-1958. In the following years the owner of the bar “Tolminska korita” and the Tolmin municipality jointly took over the maintenance of these paths. In April 2006, maintenance was entrusted to LTO Sotočje, which today maintains the paths in close cooperation with the Triglav National Park.

Thermal spring
There is a thermal spring in the short horizontal cave under the Devil’s bridge, with an average temperature of between 18.8 and 20.8 °C (the temperature of the Tolminka River is 5 to 9 °C).

The surface water penetrates underground where it is heated by the geothermal energy and then it resurfaces through the crevasses and cracks. There are quite a few such springs in Slovenia, but they are quite rare in the Julian Alps.

Devil’s Bridge
Devil’s Bridge (Hudičev most) and the road leading to the village of ZadlazČadrg were commissioned in 1907 by the Tolmin mayor’s office. The road was built by locals, together with workers from the Bohinj Railway at the beginning of the twentieth century.

Before that only a narrow path led to the village crossing the bridge in the lower level of the riverbeds.

The bridge was originally made of wood, and was later, under the Italian government, replaced with iron. At that time the bridge was given its name that is still used today.

Devil’s Bridge is a common name for bridges in Slovenia that cross narrow, deep gorges.

The Confluence of the Tolminka and the Zadlaščica, the lowest point of The Triglav National Park
As the Tolminka carved its path into the limestone, it created a wild gorge with typical joints that appear as smooth vertical plates. We can find similar ones in the Julian Alps at just one other location, namely the Mlinarica gorge in the Trenta Valley.

Going further towards the East, the Zadlaščica carved its gorge with deep erosion. The two rivers then widen and merge into, what is in fact the only confluence of gorges in Slovenia.

This confluence (“Sotočje”) lies at approximately 180 m above sea-level and is the lowest point of the Triglav National Park.

The marble trout in the Zadlaščica
The Zadlaščica is a sanctuary for marble trout. The existence of marble trout was seriously threatened by the introduction of the brown trout. The natural barriers formed by the pools of the cascades prevented the brown trout from inhabiting the water in a natural way, while difficult access prevented stocking, hence the marble trout was able to survive in its original genotype here. This fish inhabits the Zadlaščica all the way to the Skalnik farm and its affluent Jelovšček.

The »Bear’s head« and skakalce
Medvedova glava is the name of a natural bridge – a large rock which got stuck, who knows when, between the walls of the Zadlaščica canyon.

Because of excessive moisture and warmer Mediterranean climate throughout the year, the gorge boasts rich vegetation. The rock covered with moss aroused the imagination of human beings long, long ago – indeed, it looks like a hairy bear’s head.

Since the water of the Zadlaščica literally jumps from one pool to another, it creates picturesque cascades flowing through the gorge which is why the locals started calling it Skakalce or in English “the Jumps”.

The cave of Zadlaška jama (Dante’s cave)
The cave of Zadlaška jama, named after the village Zadlaz, is one of several caves through which the waters of the Soča 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.

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.
