Rafting refers to riding swift currents using thick rubber boats (I.B.S). Places where you can enjoy rafting in Korea are Hantangang River in Cheorwon, Naerincheon Stream in Inje, and Donggang river in Yeongwol. The most ideal spot is without a doubt the Hantangang River in Cheorwon. The river, situated about an hour and a half away from Seoul, is deep and clear, and filled with naturally formed Giamgoeseok rocks. Touring the picturesque area will surely leave lasting memories.
