Cheonggyecheon is an 8.4 km long, modern public recreation space in downtown Seoul. The massive urban renewal project is on the site of a stream that flowed before the rapid post-war economic development required it to be covered by transportation infrastructure. The $900 million project initially attracted much public criticism but, after opening in 2005, has become popular among city residents and tourists.
Chung Gae Chun is just a river, but it has become a popular place to visit in the past few years. It’s quite interesting because it’s in the middle of a very crowded city. One thing you might want to know, it is much more beautiful at night, especially on holidays, because they turn on the decoration lights!
