Ludi Yan and the limestone chambers of Guilin
Published on 09/15/2026 at 18:47 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Ludi Yan in Guilin is the cave better known in English as Reed Flute Cave, a limestone chamber system on Guangming Hill. Its underground route is compact, but the rock, inscriptions and coloured lighting give it a layered character.
Ludi Yan beneath Guangming Hill
The cave lies on the north-western side of Guilin in Guangxi, on Guangming Hill and near Ludi Road. It is a water-eroded limestone cave within the Guilin karst and forms part of the wider South China Karst landscape.
The mapped route runs for about 240 m, with a built path carrying visitors through a sequence of halls and connecting passages. Ceiling height and width change along the way, and the chambers open into larger spaces where stalactites, stalagmites and columns appear together.Wikipedia
Stone, inscriptions and coloured light
Inside Ludi Yan, the surfaces carry both natural formations and long human attention. More than 70 inscriptions survive in the cave, and the oldest is dated to 792, in the Tang dynasty.Tang dynasty
The cave’s chambers are lit with coloured fixtures that pick out the stone shapes against dark rock. Pools of water appear in places, and the reflections double the forms on the limestone surfaces.coloured fixtures
Guilin’s karst setting in a single cave
Ludi Yan sits within the same limestone country that gives Guilin its hills, underground voids and abrupt rock forms. The cave name refers to reeds outside the entrance that can be made into flutes, a local detail preserved in the Chinese name Lúdí Yán.Lúdí Yán
The result is a place where underground geology and recorded history sit side by side. The cave’s structure, its inscriptions and its hill setting give it substance beyond the entrance chamber and the first hall.
