Don't go deliberately, but it's still very interesting. The big stone mountain of Yadan's landform is not the same as the Yadan plain of Zhangye and other places. There are many grottoes, most of them are empty, and a few have mud plastic, or are clay plastic. You need to take a battery car to enter the door, and it takes about 18 kilometers to and from. Some of the stone steps are steeper. There is only a small section of the glass plank road that is glass, and the zipline looks more dangerous, but it should be more interesting. If you don't buy glass trestle and zip tickets, you can go around the side.
