Inwangsan (인왕산) is a mountain in the city of Seoul. It’s one of the four of Seoul’s inner mountains and is situated to the north-west of Namsan Seoul Tower. The highest peak is 338.2m. The difficulty level is easy to intermediate, if your medical condition allows it. I suggest bringing enough water and a towel on warm days, and good all-terrain hiking shoes that are comfortable to wear. In winter time, especially on Icy days, watch your steps carefully.
