Enjoy the day and night of Seoul
A park on the mountain where the Hanyang Fortress is located along the ridge. It is a place where you can see the most stunning night view in Seoul and boasts a spectacular city view of the N Seoul Tower. Along the fortress, there is the Seoul Fortress Wall trail, which runs from Hyehwamun Gate to Heunginjimun Gate, so you can enjoy the panoramic view of Seoul while taking a walk. Many couples enjoy going on dates here because there is so much to see and do in the surrounding cafe street and Ihwa Mural Village.
