Created by the relentless work of the Pivka River over several millennia, Postojna Cave is a 24,120 meter long cave system near Postojna in Slovenia. The system consists of a range of passages, galleries and chambers carved out of karst rock. The caverns are filled with spectacular calcite formations, stalagmites and stalactites, of all ages, in all shapes and colors, some of which are enormous.

Electric lighting, installed in this very popular tourist destination in 1884, allows visitors to see the magnificent shapes and forms, including some very rare cave animals. Today’s visitors can travel through the caves by train in a guided tour that lasts about hour and half. Map
