Sibiseonnyeotang Valley (Valley of the Twelve Angels’ Bath) is located at the base Seoraksan Mountain. It is also referred to as Tangsugol or Tangsudong Valley. The valley got its name from a myth that angels once came down to bathe in its flowing rivers. However, there are only eight baths.Due to fluvial erosion, there is a steep hole in this valley, and many baths and waterfalls of various shapes are stretched over an 8 km distance. Pass Ungbong Waterfall and the first bath and Dok-tang appear. Then walk past Buk-tang, Rainbow-tang, Peach-tang, and the path will end with the last bath, Yong-tang.Of these baths, the 7th bath is called Peach-tang, named after the traditional shape of the bath. The deeply delved rock behind the back of the waterfall is more beautiful than the bath under the waterfall. Past the Peach-tang is another clean, steep bath. From there, a 5-minute walk to the right will lead you to another waterfall and a pool. The water from Daeseungryeong and Mt.Ansan is connected to Namgyo-ri, Buk-myeon. This is an 8-km valley, which takes approximately two hours from the baths to Namgyo-ri. There are iron bridges over the baths for visitors to cross.
