The 11 interconnected chambers that compose the Škocjan Jama stretch for almost 6 km (about 4 miles) through a dramatic, subterranean landscape so unique that UNESCO has named them a World Heritage Site. The 90-minute walking tour of the two chilly main chambers—the Silent Cave and the Murmuring Cave—is otherworldly as winds swirl around the dripstone sculptures, massive sinkholes, and stalactites and stalagmites that resemble the horns of a mythic creature. The highlight
is Europe's largest cave hall, a gorge 479 feet high, 404 feet wide, and 984 feet long, spanned by a narrow bridge lighted with footlights. Far below, the brilliant jade waters of the Reka River rush by on their underground journey. The view is nothing short of mesmerizing.
