These caves which go by various names (Thousand-Buddha Gap, Yulin Caves/Grottoes) are magnificent and, in my view just as good as those at Mogao. However, at the time of writing (4/17) it is something of a challenge to reach them. But, my goodness it was worth the effort. The presentation is not on the same level as the introduction at Mogao. Indeed, there is no introduction but the caves are marvellous. The road is gravel most of the way but it looks as though it is being upgraded. As a result there were less than 100 visitors. The caves are either side of the river where it runs through a canyon. The paintings are remarkably well preserved. 43 caves are from the Tang, Five Dynasties, Song, Western Xia, Uiger, Yuan and Qing dynasties. We were only a small group and so received almost personal attention and the caves were much bigger than Mogao and very cold once inside. Some of the black ink drawings were exquisite. There has been some restoration carried out some 100 years ago to the figures and to the paintings so the colours are quite bright but a great deal of the art is original. There is little in the way of facilities although a new visitor centre is being built. I would suggest one takes one's own torch although the guide will have one but the caves are large.
Clearly the site will, in due course, be on the tourist route but I would suggest one visits whilst it is so simple and charming.
