Dongsaengmal Observatory sits at the entrance of the Igidae Urban Nature Park in Yongho-dong, looking out over Gwangandaegyo, Marine City and Haeundae. From it, a small harbor below and Dongbaekseom are visible in one view. It marks both the start and the end of the Igidae coastal walk, about 5 km from Oryukdo and roughly two hours at a slow pace. The route climbs and descends over hills and stairs, so it is not a light walk.
