Ludi Yan in Guilin is a limestone cave where Guilin’s karst landscape continues underground as a sequence of chambers filled with stalactites, stalagmites and coloured light. Formed in carbonate rock laid down in the Mesozoic era, it sits on the north-western side of Guilin in southern China, in the Guangxi Zhuang Autonomous Region.
Limestone, karst hills and an underground gallery
Ludi Yan is a natural limestone cave carved in the flank of Guangming Hill, a karst hill rising on the north-western outskirts of Guilin. The cave extends for about 240 m (787 ft) in length, creating an underground route that visitors follow through a succession of chambers and passages, with the rock roof above rising to a maximum height in the region of 18 m (59 ft).massive limestone cave over 180 million years old The surrounding hill and the cave are part of the wider Guilin karst landscape, where steep limestone peaks and valleys have been shaped over long geological time.
The limestone of Ludi Yan belongs to strata dated to around 180 million years ago, meaning the rock itself formed in the Jurassic period even though the cave void is far younger.Alter über 180 Millionen Jahre Over hundreds of thousands of years, groundwater circulating through fractures in the limestone dissolved channels and chambers, leaving the present cave as part of a broader network of karst features around Guilin.natural limestone cave formed over hundreds of thousands of years
Stalactites, stalagmites and coloured illumination
Inside Ludi Yan, the main attraction is the density and variety of dripstone formations created by mineral-laden water. Stalactites hang from the ceiling, while stalagmites rise from the floor and sometimes meet to form pillars, along with curtains and flowstone that cling to the walls.stalactites, stalagmites, stone pillars and rock formations The formations take on shapes that visitors compare with familiar objects, landscapes and figures, giving each chamber a distinct character.
Artificial lighting highlights the rock surfaces, picking out the textures and patterns on stalactites and stalagmites. The coloured lights trace the outlines of formations and reflect off pools and the damp limestone, creating a visual contrast between the natural mineral surfaces and the vivid illumination.bunt beleuchtete Karsthöhle aus Kalkstein In places, historical ink inscriptions on the rock record past visits, including stone inscriptions dating back to the eighth century AD, adding a human layer to the geological story of the cave.more than 70 stone inscriptions dating back to 792 AD
