Muak-san Dongbongsudae is a historical site on the summit of Ansan in Seodaemun-gu, Seoul, overlooking the city. It is the eastern of Muak-san's two bongsudae, with views in all directions toward Bukhansan, Inwangsan, Namsan, and the Han River. From Exit 5 of Dongnimmun Station, the climb toward Muakjae Haneul Bridge reaches the summit in 30 minutes, with stairs and roads maintained along the way. There is no lighting at all, so hiking at night is difficult.
