The entire length of the Yellow Dragon Cave is about 12 km (7.5 mi) and it has 4 distinct levels. There are dry caves and watery caves including 2 palaces, 8 halls and 96 corridors, sure to satisfy any avid spelunker. Stalactites and stalagmites fill the whole cave. And if you can bring yourself to do it, when you whack a stalactite hard enough it will resonate at a certain pitch. There's also an 11 km (7 mi) long cave and a 50 meter (164 ft.) high waterfall to be explored.
