Škocjan Caves

As I said before, so far I only visited caves in Majorca, Spain, and it was very cool! But these caves seem to be also something spectacular!

Škocjan Caves represents the most significant underground phenomena in both the Karst region and Slovenia. Škocjan Caves was also entered on the List of Ramsar wetlands of international importance on 18 May 1999. Together with the underground stream of the Reka River, they represent one of the longest karst underground wetlands in Europe.

Explored length of caves is 6,200 m, caves have formed in 300 m thick layer of Cretaceous and Paleocene limestone.

The Reka River disappears underground at Big Collapse Doline (Slovene: Velika Dolina) into Škocjan Caves and then flows underground for 34 km surfacing near Monfalcone where it contributes approximately one third of the flow of the Timavo River, which flows 2 kilometers from the Timavo Springs to the Adriatic Sea. The view of the big river in the rainy season, as it disappears underground at the bottom of Big Collapse Doline, 160 m below the surface, is both majestic and frightening.

The exceptional volume of the underground canyon is what distinguishes Škocjan Caves from other caves and places it among the most famous underground features in the world. - in: wikipedia
