Found in the north­west of Hunan Province in Chi­na, these stag­ger­ing lime­stone pin­na­cles are cov­ered in lush green­ery and often shroud­ed in mist. A cable car goes as far as Huang­shi vil­lage and from here there are plen­ty of trails to take in the breath­tak­ing views of Tianzi (‘son of heav­en’). Unsur­pris­ing­ly, they are the inspi­ra­tion for the float­ing moun­tains in the block­buster movie Avatar.
