Dragon Palace Cave, China

In the western suburbs of Anshun in Guizhou Province, there exists a magnificent underground cave system with lakes, waterfalls and stalactites, covering an area almost 60 square kilometers (about 23 square miles). Because the main cave looks like the crystal palace where the dragon king lives, it is known as Dragon Palace Cave.

The scenic spot has four main areas, namely, the Rape Lake, the Whirlpool, the Leech Pass and the Dragon Palace itself. Among them, as the most famous and wonderful scenic spot, the Dragon Palace includes various Karst (Limestone) landscapes, solemn steep cliffs and jagged stone forest. The longest underground river in China, some 5,000 meters (over 5468 yards) in length flows beneath more than 30 hills connecting over 90 limestone caves within this scenic spot.
