Huanglong Dong (Yellow Dragon Cave) is located in the Wulingyuan Scenic and Historic Interest Area. This area has spectacular ravines and gorges. The rocks are a mixture of 2/3 quartzite and 1/3 limestone, and while the quartzites form strage rock formations and gorges, the limestone is heavily karstified. The caves are concentrated in the Suoxi River area, where about 40 caves are known. Others are found at the south-east side of Tianzi Mountain.
Huanglong Dong is one of the ten longest caves in China, 11km of passages in four levels. The Chinese are rather acribic in counting the features, so cave contains 13 chambers, 96 passages, 3 waterfalls, 2 underground rivers, 3 pools, and 1 underground lake. Although this list seems a little strange to western eyes, it is still impressive.
Other superlatives are more in the gusto of westerners. One of the waterfalls is breathtaking 50 meters high, the biggest chamber has a floor of 4,000m². And there is a stalagmite called the Holy Needle, which is 19.2m high but only 10cm in diameter. Legend tells, it protects the Dragon King who resides in the dark depths. Because of its value for tourism it was insured in 1998 for 100 million yuan (US$12.1 million). The cave is visited by boats on the cave river.
