Located 35km west of Dunhuang, there are 16 caves hidden in the cliff face of the Dang River (Dǎng Hé, 党河) gorge, ranging from the Northern Wei to the Tang dynasties. Take an afternoon departure to catch a glorious desert sunset. You will need to arrange a private driver to take you here, or enquire at Charley Johng's Cafe for current bus tours.
