In the spring of 2019, A'Bang and a group of climbers from Yangshuo, along with the Just Take Guest House, cleaned and climbed over 80 boulder problems. The boulders are mostly conglomerate limestone, but there are also a few which are granite.
The boulders are located in two main areas along the river. The closest area is near the the cave, around 20 minutes walk away. The boulders there can only be climbed in the spring when the water level in the river is low enough.
The other area is called "Secret Garden" and is about 8km from the guest house. Most of the boulders there can be climbed all year round. There is also a small sports crag with 6 short and steep bolted routes.
The free guide book was released as a Wechat article and can be viewed here.
