Huanglong Cave

Huanglong Cave is renowned for its lofty caverns, deep underground rivers, and dense stalagmites. The cave is adorned with various stalactites such as stone milk and stone pillars, which appear vibrant under the lighting. Particularly notable is the iconic attraction "Sea-fixing needle": Nearly 20 m tall, thick at both ends and thin in the middle, with the thinnest part measuring only approx. 10 cm in diameter. It is estimated to have grown for nearly 200,000 years and is still slowly 'growing taller'. The attraction once invested heavily in insuring it, demonstrating its rarity.

After passing the ticket office of Huanglong Cave, there is still some distance before entering the cave. Besides the long corridor for queuing, there is also a spectacular group of interconnected waterwheels. This attraction fully utilizes the underground water resources of the cave, featuring waterwheels with various functions, shapes, and purposes, such as grinding flour and irrigation. With designs ranging from pagodas to mechanical types, the exquisite craftsmanship resembles a real-life "Mohist mechanical city," leaving visitors in awe.

Huanglong Cave covers a vast area, stretching approx. 7 km in total length with a vertical height of over 100 m inside the cave. The entire cave features interconnected chambers and underground rivers. Travelers can admire a large quantity of stalactites in various forms such as stone milk, stone pillars, stalagmites, stone curtains, stone pianos, and stone flowers. Among them, the most distinctive is the iconic attraction inside the cave – Sea-fixing needle", thick at both ends and thin in the middle, is estimated to have grown for two hundred thousand years.

The "land-and-water" sightseeing route in the cave is particularly fascinating. Travelers first explore on foot, then board a cruise at the dock by the underground river to admire the scenic views and spectacular stalagmites along the waterway. The cruise lasts about 15 mins. After disembarking, the walking tour continues, leading to a magical cave waterfall. The route is one-way, with the exit located near but separate from the entrance.
