Hwamyeong Eco Park, which runs along the Nakdonggang River, is a path that anyone can walk comfortably. Aegiso Valley in Daecheoncheon Stream is said to be called the 'Aegi (child)-so (swamp)' because a woman was so distracted by the surrounding scenery that she did not even know that her child had drowned. If trekkers walk a little further, they will see Geumjeongsanseong Fortress, the largest mountain fortress in Korea. Currently, while the area is being restored bit by bit, citizens voted to name the West Gate as 'Haewolmun Gate' and the East Gate as 'Gwanhaemun Gate'.
