Divje jezero is a karst siphon lake (Vaucluse spring), located approximately 2 km south of Idrija. The type of karst spring - Vaucluse spring is named after the Fontaine-de-Vaucluse spring in the Vaucluse region of Provence in southern France, east of Avignon. Springs of this type are characterized by the fact that water flows to the surface from great depths under pressure through steep channels. The lake lies in a stone cauldron under the hundred-meter cliffs that border this northern edge of the Črnovrška plateau. Divje jezero is also a karst spring, as water flows into the lake from a steeply descending trench, which has been explored to a depth of 160 m so far. Although the lake surface is usually calm, after heavy rains there can be strong eruptions of water, up to 60 m³/s. The Jezernica River flows from Divje Jezero, which is the shortest surface-flowing river in Slovenia and flows into the Idrijca River after 55 meters. The water temperature in the lake fluctuates only between 7 and 10 °C throughout the year. The lake was protected as a natural monument in 1967 and since 1972 has been arranged for visitors as the first Slovenian open-air museum.

I recommend a visit by bike or on foot. The lake is truly beautiful but at the same time eerie, as we do not know its exact depths. The shortest river, Jezernica, flows out of it, which flows into the Idrijca after a few meters. You start at one of the larger parking lots in Idrija, from where it is about 3km to Divje Jezera. An ideal starting point also for those who visit the city with a camper. On the way to the lake (if we pay attention), we can see the remains of the Italian caves and bunkers.

A small hidden lake near the road. The lake has a cave under the water surface. This is 160m deep and about 460m long. Divers have already explored these.
