They said that Cheonggyecheon Stream existed only as a neglected waterway hidden by an overpass. But today, it has been transformed into a haven of natural beauty amidst the bustle of city life. It passes close to Deoksugung Palace, Seoul Plaza, the Sejong Center, Insa-dong Street, Changdeokgung Palace, and Changgyeonggung Palace, allowing visitors to easily visit major tourist sites after a leisure stroll along the stream.
After DDP, I walked alone the Cheonggyecheon stream. It's very serene with small waterfalls, and nearly two dozen overhead bridges. As it was so cold, the water near the rocks are getting iced.
They said that, many people usually go here during summer more than winter.
Cheonggye Plaza never goes to sleep; visitors can enjoy the fantastic display of light and water even at night.
