Cheonggyecheon Stream

Cheonggyecheon has existed as a stream since the Joseon dynasty (Korea's royal era, 1392–1910), but it was gradually paved over starting in 1958, and in 1971 an elevated highway was built directly on top, burying it completely under concrete. Demolition of that highway began in July 2003, and the restored stream reopened in its current form in September 2005.

Honest heads-up: the water flowing through Cheonggyecheon isn't a natural spring. The stream's own flow alone can't sustain its current form, so about 40,000 cubic meters of water is pumped in daily from the Han River and groundwater. Some critics describe it less as a 'restored natural stream' and more as an 'artificial water feature running through downtown.'

Local tip: the full walking path runs over 17km, so walking it start to finish (from Cheonggye Plaza near Gwanghwamun to the end) takes more than 3 hours. For a shorter visit, the stretch from Cheonggye Plaza to Gwangjang Market (about 30 minutes) packs in highlights like the mural of King Jeongjo's royal procession. Evening, once the lights come on, is the most photogenic time.

Free, walking path open 24/7. A 2-minute walk from Gwanghwamun Station Exit 5 (Line 5) to Cheonggye Plaza.
