Longmen Water Cave was a recently opened sights, in Longmen vilige, 3km from Moon Hill. It is the largest and one of the most exciting natural caves to explore in Yangshuo. The whole cave is about 3km long and runs through 3 mountains. The water in the cave is 0.5m deep and has a gentle flow which is clean and safe.
Used as refuge by the local villagers from the invading Japanese army during WW II , the cave draws its name from a tiny stalagmite resembling the Maitreya, located a short distance inside the cave. It's easy to see why the locals thought the cave secure from the Japanese and why portions are still off-limits to visitors. The cave is full of narrow, maze-like, and sometimes dangerous passages. Be warned, even in the areas open to the public there have been injuries during the cave's 10 years as a tourist attraction. A guide and a flashlight are necessary, and it is necessary to crawl through muddy holes, climb up and down stalagmites, and sidle in between stalactiteswith the aid of ropes and ladders. The cave is the most extensive, unaltered subterranean micro cosmos in the area. Complete with stalactite "drums" and an underground waterfall pool , you can bathe and swim. Bring your swimsuit and towel.
