Shall we enjoy the sunset and night view at the lake park after work? / Seoul trip / Korea travel 

Ilsan Lake Park is truly a vast and pleasant place to go for walk.
There is not a single bad place to be found anywhere.
In Ilsan, located which is a bit north of Seoul,
cherry blossoms bloom a little later than in Seoul.
If you missed the cherry blossoms in Seoul due to the spring rain, that just fell, I recommend visiting Ilsan Lake Park.
