Chuiyun Tongtian River Cave
垂云通天河
An underground karst river cave in Yaolin Town. Boats carry visitors along a kilometer-long channel, and the site also offers a glass bridge, slides and other mountain attractions.
Chuiyun Tongtian River lies in Dongling Village, Yaolin Town, not far from Yaolin Fairyland. It is a karst underground river about 4.5 km long, of which roughly 1,000 m can be explored by boat. Stalactites and stone curtains are reflected on the water, and lighting creates a dreamlike effect. The cave stays at about 18°C year-round. The site has developed attractions including a glass bridge, a Sky Coaster and a Sky Glide slide, plus water shows at night. Ticket prices vary widely between basic boat trips and packages, so book online and check the official notices. Weekends are crowded, so weekdays offer a better experience. It is about a 30-minute drive from Tonglu county seat.
