The Xiaoqikong (Small Seven Holes) Ancient Bridge is a Qing-dynasty stone arch bridge spanning a fast-moving river, its seven low arches barely above the waterline. The bridge is small and simple, but it names the entire scenic zone and serves as its visual symbol: the image of the seven arches reflected in the water, surrounded by subtropical forest, is what appears on every piece of Libo promotional material.
The bridge is the entry point to the Xiaoqikong scenic walk, which leads upstream through a gorge with multiple scenic features: the 68-step cascade, a staircase waterfall dropping through successive limestone pools; Wolong (Crouching Dragon) Pool, a large still section with mirror-like reflections; and the Water Forest, where trees grow in flooded ground with their roots submerged in the turquoise stream. The walk from the bridge to the Water Forest takes about two hours at an unhurried pace.
The karst river chemistry that creates the turquoise colour — calcium carbonate supersaturation in the water — is the same mechanism as in Plitvice Lakes in Croatia and Jiuzhaigou in Sichuan, but the combination here with subtropical broadleaf forest produces a visual density those other sites lack.
