Taktsang Monastery, also known as the Tiger's Nest, clings to the slide of a cliff about 10,000 feet above ground in Bhutan's Paro district. The monastery was built in the 17th century and damaged in a fire in 1998.
Visitors can reach the monastery by mule ride or by foot. Walking takes about two hours from the base of the trail. The monastery is still used, and entry is restricted.
