Yixiantian (A Thread of Sky)
一线天
A rock crevice more than 100 meters long, split from a giant boulder. Its narrowest point is only about 30 centimeters wide, so you must squeeze through sideways in the dark. It is one of the most unusual landforms in Wuyi Mountain.
Yixiantian, or 'A Thread of Sky', lies in the Linyan rocks south of the Nine-Bend Stream. A giant Danxia rock mass has been split by a fissure, forming a crevice about 170 meters long and nearly 50 meters high, with a narrowest point of only about 30 centimeters. Looking up from inside, you see only a thin line of daylight, hence the name. Visitors must squeeze through sideways in the dark. The cave is damp with dripping water and is home to the rare white bats. Near the exit are the Wind Cave, the Immortal Cave and other sights. Passing through and touring the surrounding area takes about 30 to 60 minutes. It is included in the main Wuyi Mountain scenic area ticket, and sightseeing shuttles stop at the Yixiantian station. It is often scheduled in the same morning as Huxiao Rock. The passage is one-way, and lines are long in peak season. Those with claustrophobia or larger builds should think twice. A headlamp or phone light is handy.
