Opis:
Caves don't have to be big to be beautiful. The Orleška Jama near Sežana (Slovenia) for instance: it's only 138 meters long and 33 meters deep, but it's absolutely interesting.
After descending the 15 meter entrance pit you enter the cave. A 3 meter drop into the main chamber leads to a second and a third chamber, each richly decorated with beautiful speleothems. Don't forget to bring your camera!
