Well this place I really enjoyed very much as It is one of the most artificial place that I ever seen , and this place to make sure that u didn't miss anything you mist either visit twice one in the morning and one in the evening or plan to visit before sunset so u can have daytime view and night time view , this place is one of the very romantic place for Korean people and for tourist as well once you visit you will find a lot of Korean couple enjoying there romantic set and place add to that some family as well , when u visit that place make sure you have some coin with u as there is speichial place you can through for your luck inside the water .
Don't miss this place and upper side of this place you will find fountain beside two big statchu for sachung king the one who created hangul ( Korean alphabetical ) and other one is for famous Korean war leader who protect korea from Japan invasion before .
Plan to spend at least 4 hrs in the place and don't miss the fun
Good luck
