Dong Bang-i is a collection of sectors to the southeast of Huai Khee Lek reservoir near Nikom Kham Soi. While this topo currently only covers three sectors, there are many more hidden in the forest that covers the mountains here.
- Apes is a convenient little roadside sector with low boulders and good landings.
- Horrorzone is a largely unexplored and undeveloped zone deep in the jungle with good rock quality and quite a bit of potential.
- Phu Dan Sung is by far the best sector here and, together with Radar Station at Phu Mu, the best sector in the area. It hosts several world-class lines, such as Crown of Creation or กินรี, as well as several hard projects such as the Garden of Hedone and the Iron Nun, which will be top boulders in their own right.
Phu Dan Sung is a place of legend, and locals tell stories of the spirits that haunt the mountain in the night. When it gets dark, they say, you have to keep the doors locked and don't answer their knocking, their begging and their deceptions, or a terrible fate will find you. Much more concrete, however, is the risk of snakes around here, as they live under several boulders (such as the Doormouse, Crown of Creation and กระสือ). They are generally more scared of you than you are of them, but they are hard to spot under the dry leaves and some of them are toxic. Exercise caution.
