This 5.6 kilometer long stream is welcome sight in the city. Walking past this stream can clear your mind and help you relax. The stream is almost 5 meter below street level, helping you separate your mind from the busy streets. At some places there are waterfalls or places to sit. The stream used to be a large freeway straight through the city, but was turned in to the stream as a part of plan to make Seoul greener and healthier.
