The caves are now a UNESCO World Heritage site with a huge and long cavern several hundred feet from the river bottom to the top of the cavern. 40,000 year old dripstones, stalagmites and stalactites, form throughout. Could not take pictures inside the cave but only at the natural opening. A 3 km walk on steps and bridges throughout the dimly lit caves was like walking through a movie set of Lord of the Rings or Indiana Jones. One of the only animals present in the cave besides bats is a white salamander with alabaster human-like skin.
