The world's largest karst landscape, spread across 4 provinces and inscribed in 2 phases (2007, 2014). Stone Forest (Yunnan), Libo (Guizhou), Wulong (Chongqing), Guilin (Guangxi).




The Stone Forest near Kunming is the strangest landscape in China — a petrified forest where the "trees" are 30 m limestone pinnacles. It gets crowded, but arrive at 7:30 AM opening and walk the outer ring (8 km) rather than the inner loop (2 km, packed). The outer ring is nearly empty and the pinnacles are taller. Guilin's Li River between Yangdi and Xingping is the karst experience everyone knows from Chinese paintings; the 4-hour bamboo-raft ride is the best ¥400 I have spent in China.
Guilin/Yangshuo if you want the classic Chinese-painting landscape and developed tourism infrastructure. Stone Forest if you are based in Kunming and want something otherworldly. Libo if you want pristine cone karst and are willing to trek further. Wulong if you are in Chongqing and want giant sinkholes and natural bridges. They are different experiences — choose based on your route, not a ranking.
Stone Forest (Yunnan) to Libo (Guizhou): ~600 km, no direct transport. Libo to Wulong (Chongqing): ~500 km. Wulong to Guilin (Guangxi): ~700 km. Each cluster is a separate trip of 1–3 days from its nearest city. Do not attempt to string them together as a "karst tour" — you will spend 80% of your time in transit.
The inner loop is crowded and gift-shop-heavy by 10:00 AM. The outer ring (8 km, signposted but less promoted) is genuinely excellent — you walk through forested karst with towering pinnacles and see maybe 20 other visitors in 3 hours. Arrive at 7:30 AM and do the outer ring.
2 full days. Day 1: Li River bamboo raft from Yangdi to Xingping (4 hours, ¥400) + Xingping old town. Day 2: Yangshuo countryside cycling (free, bike rental ¥30) through karst valleys + Xianggong Mountain sunset. 3 days adds the Longji Rice Terraces (2h from Guilin).
Karst is a landscape formed by the dissolution of soluble rocks (limestone, dolomite) by water over millions of years. The name comes from the Kras plateau in Slovenia, where the phenomenon was first scientifically studied. South China has the world's largest and most diverse karst formations, hence the UNESCO serial inscription.
