The Shunan Bamboo Sea — literally 'the bamboo sea of southern Sichuan' — is exactly what the name promises: some 70,000 mu of nann bamboo pouring over 28 hills and 500 smaller rises in Yibin's far south, so dense and so green that from a lookout it moves like water. This is the largest original bamboo park in China, holding 58 species, and its plant cover runs to 87%, so the air stays noticeably clean.
The park is built around a handful of set pieces. The Jade Corridor is the signature: a stretch of road paved in red sandstone, the local stone, and canopied so tightly by leaning bamboo that it feels like a tunnel. The Guanyun or 'sea-view' tower, reached by one of China's longest cable cars, gives the sweep over the whole green ocean. And in the cliffs, the Xianyu Cave temple and the Tianbao Stockade hold Ming-dynasty carvings and a Qing-era fortress gate respectively.
Between the set pieces, the park is a place for slow, damp, green idling: drifting a bamboo raft across a lake, walking the Wangyou Valley by moonlight, listening to the water in the Qicai Falls gorge, and cooling off in air that stays near 15.5°C year-round. It is not dramatic mountain scenery; it is soft and enveloping, and that is the point.
The food is part of the draw, and the park is the one place to eat it: the full-bamboo banquet that runs from fresh winter and spring shoots to bamboo fungus, bamboo 'bird's nest' and preserved bamboo shoots. Add Yibin's own famous ranmian noodles and ye'erba, and this is as good a reason to come as the green.
