Reed Flute Cave interior
Reed Flute Cave (Ludi Yan) is located in the northwestern section of the city. It is 240 m deep and is probably the largest and most magnificent cave in
Guilin. Ludi Cao, reed grass, grows in front of the cave and can be
used to make the most wonderful flutes. This was what gave the cave its
name. It used to be a favorite place for the local people to hide
themselves in times of war or trouble.
An inside view of Seven-Star Rock
Seven Star Park is one of Guilin's most important sights on the
Lijiang's west bank. The seven stars symbolize the seven mountains
around which the park grounds were laid out. The mountains are arranged
in the order of the seven stars in the Big Dipper. The four northern
mountains make up Putuo Shan, the three southern mountains from Yueya
Shan. Many large caves are located on Putuo Shan. Qixing Yan, Seven
Star Cave, is one of these.
