Step down a few flights of stairs in the middle of downtown Seoul and, almost instantly, the sound of traffic recedes. You are now four to five meters below street level. Water flows from west to east. Above your head, office windows along Euljiro scroll past. Cheonggyecheon is the strangest walking path in Seoul. It has been a Joseon-era sewer, a shantytown, a concrete expressway, and now — once again — a stream. Walk its 22 bridges in order, and all four of those lifetimes pass beneath your feet, one after another.
The short answer
- The restored section is 5.84 km long, with 22 bridges. The first bridge is Mojeongyo; the last is Gosanjagyo. Walking straight through takes about 1.5 hours; taking it all in takes about 3.
- The history is concentrated upstream. The Jeongneung tomb stones under Gwangtonggyo, the 186-meter King Jeongjo Royal Procession mural, Supyogyo, and the Oganusumun water-gate ruins all sit within the first 2.7 km.
- Short on time? Walk Cheonggye Plaza to Ogansugyo only. It ends at Gwangjang Market and Dongdaemun, so your next destination is right there.
What was Cheonggyecheon, originally?
Hanyang — the old name for Seoul — sits in a basin ringed by mountains on all four sides. Water had nowhere to go but straight through the center of the city. The stream was already there long before Joseon chose this site for its capital. The problem was that the flow swung wildly with the seasons. In spring and autumn, the streambed lay bare and dry — a geoncheon (dry stream). Come summer, even modest rainfall would send it over its banks, swallowing houses and tearing bridges away.
So King Taejong, almost immediately after taking the throne, began digging out the riverbed and raising the embankments. The decisive push came in December 1411, when he established a temporary office — the Gaecheon Dogam (Stream Dredging Bureau) — and launched a massive one-month campaign starting on the fifteenth of the first lunar month the following year. The workforce: 52,800 men. They lined both banks with stone and rebuilt Gwangtonggyo and Hyejeonggyo as stone bridges. The common noun gaecheon (開川), meaning “to dredge a stream,” became the stream’s proper name after this project.
King Sejong's verdict — auspicious waterway, or sewer?
Two arguments faced off: in feng shui terms, Cheonggyecheon was the *naesu* (inner water) flowing through the heart of the capital and had to stay pure at all times. The counterargument: a city this densely populated absolutely needed a watercourse to flush its filth away. Sejong sided with the latter. That decision locked Cheonggyecheon into its role for the next 500 years — as Hanyang's working stream and open sewer. In 1441, he had a stone pillar carved with measurement lines installed in the water west of Majeongyo to gauge the water level. That pillar was the supyo (water gauge), and it is where Supyogyo — the Water-Gauge Bridge — got its name.
Why was it covered? And why was it opened again?
Liberation, then war. By the 1950s, Cheonggyecheon had become the part of Seoul no one wanted to look at. Refugees built shacks along the banks — half on land, half cantilevered over the water — and raw sewage flowed through the middle. Mid-1950s Cheonggyecheon was the city’s slum, no qualifiers needed.
The cheapest, fastest solution was to bury it. The covering began in 1955 with a 136-meter stretch upstream from Gwangtonggyo. By 1958, full-scale construction was underway, and by 1977, the entire stream — all the way to Sindap Railway Bridge — had vanished under concrete. Overhead, the Cheonggye Expressway rose in 1971: 5.6 km from Gwanggyo to Majang-dong, 16 meters wide. At the time, it was a proud symbol of modernization. Seoulites genuinely showed it off to visitors.
Thirty years later, the same structure read in exactly the opposite way. The underbelly of the expressway had become the darkest, loudest corner of downtown, and engineers kept flagging the aging support columns as unsafe. The expressway closed on June 30, 2003. Restoration work began the next day. Two years and three months later, in October 2005, water flowed again.
🕰️ Cheonggyecheon: Six Centuries at a Glance
| Period | What Happened |
|---|---|
| 1411–1412 | King Taejong establishes Gaecheon Dogam and launches a one-month dredging campaign. Gwangtonggyo rebuilt in stone |
| 1441 | King Sejong installs the supyo water gauge west of Majeongyo — Joseon’s own stream-level meter |
| 1760 | King Yeongjo orders a massive dredging operation. After this, regular dredging becomes institutionalized |
| 1955 | First covering: 136 meters upstream from Gwangtonggyo |
| 1958–1977 | Full coverage completed from Gwanggyo to Sindap Railway Bridge |
| 1971 | Cheonggye Expressway completed — Gwanggyo to Majang-dong, 5.6 km |
| June 30, 2003 | Expressway closed. Restoration breaks ground the following day |
| October 2005 | Restoration complete. Water returns to 5.84 km of the stream |
Where does the water come from now?
No natural flow remains. 40,000 tons per day are pumped in from the Han River and treated, plus 20,000 tons of groundwater from subway and power infrastructure — all released at the upstream end. The water is clean enough for minnows and pale chub to thrive, but E. coli and turbidity levels fall short of drinking-water standards. This is also why a persistent criticism has dogged the restoration from the start: that it is not a natural stream at all, but "a giant ornamental fish tank."
Where do you start, and how far can you go?
You start at Cheonggye Plaza, right beside Gwanghwamun. You finish at Gosanja-gyo (Gosanja Bridge) in Seongdong-gu. The plaza-to-bridge distance is roughly 5.5 km. The walking path itself continues another 300 meters or so, officially ending at the Sindap Railway Bridge. There, Cheonggyecheon meets the Jungnangcheon, which flows a bit farther south and empties into the Han River.
What matters most: you can exit anywhere. There are 65 access points — 42 stairways, 21 ramps, and 2 elevators — and subway Lines 1, 2, 3, 4, 5, and 6 keep crossing overhead. Think of each bridge as a way back up to the surface.
🚶 Choosing Your Section by Time
| Section | Distance | Walking Time | Character |
|---|---|---|---|
| Cheonggye Plaza ~ Gwansugyo | ~1.3 km | 20 min | The densest stretch of relics and murals |
| Cheonggye Plaza ~ Ogansugyo | ~2.7 km | 40 min | History + markets. The ideal half-day route |
| Ogansugyo ~ Gosanja-gyo | ~2.6 km | 40 min | The crowds thin out; the sound of water grows |
| Cheonggye Plaza ~ Sindap Railway Bridge | 5.84 km | 1 hr 30 min | The full walk. With photos and pauses, allow 3 hours |
Always walk upstream to downstream
Start at Cheonggye Plaza in the west and walk east — that way you move with the current, and the sights unfold in chronological order. Walking the other direction puts the Joseon era at the end, which makes no narrative sense. From Gwanghwamun Station Exit 5 (Line 5), it is 100 meters — a two-minute walk to the plaza.
Upstream — Cheonggye Plaza to Supyogyo (1.1 km)
This is where the water begins. More precisely, where it is made to look like it begins — a two-tier waterfall drops four meters and announces that the stream starts here. At the edge of the plaza stands Spring, a 20-meter-tall, 9-ton spiraling sculpture in red and blue. It is a 2006 piece by Claes Oldenburg and Coosje van Bruggen, and its form — and the story of its installation — still divides opinion. Ask a Seoulite what it looks like, and the most common answer you will hear is “a conch shell.”
Gwangtonggyo — a bridge built from a queen’s tomb
The second bridge, Gwangtonggyo, spans just 12 meters — the shortest of the 22. But climb down and examine the abutments, and a different story begins. Intricately carved stones are mixed into the masonry, and some of them are unmistakably upside down.
When a great flood swept Gwangtonggyo away in 1410, King Taejong ordered workers to salvage the stone burial screen from the old tomb site of Queen Sindeok — the second consort of King Taejo, the dynasty’s founder. Queen Sindeok was the mother of the rival prince whose very existence had driven Taejong to stage his coup. The stones that had guarded a queen’s grave were now laid beneath the most heavily trodden spot in the capital. Joseon politics, preserved in a single block of granite. The twist: Gwangtonggyo went on to become the most crowded bridge in all of Hanyang during the Jeongwol Daeboreum daribapgi (bridge-treading ritual), when people believed walking across a bridge under the first full moon of the lunar year would bring them sound legs for the year ahead.
King Jeongjo’s Royal Procession — a 186-meter painting you walk beside
Pass Gwangtonggyo and head toward Jangtonggyo, and the wall on your left turns into one continuous painting. It depicts the 1795 procession of King Jeongjo, who rode with his mother, Lady Hyegyeong, to visit the tomb of his father, Crown Prince Sado, in Hwaseong. The original painting was transferred onto white-ceramic tiles, fired, and mounted along the wall — 186 meters of horses, palanquins, musicians, and banners, stretching as far as the mural itself runs. Walk at an easy pace and the speed of the procession eerily matches your own. To see the whole thing, stay on the side of the stream where the wall is — not the opposite bank.
Supyogyo — the bridge without its original
The sixth bridge carries the name Supyogyo, but the Joseon-era Supyogyo is not here. It was dismantled during the 1959 covering works and relocated to Jangchungdan Park, where it still stands. It was not that they never intended to bring it back. The problem was simpler: the restored stream channel is 23 meters wide, and the original Supyogyo is 26.5 meters long. It physically would not fit. What stands here now is a temporary footbridge marking where the real one used to be.
Midstream — Gwansugyo to Ogansugyo (1.5 km)
Here the character of Cheonggyecheon shifts. Instead of relics, you get markets. The Sewoon Sangga arcade passes overhead. The smells of packaging supplies and spices drift down from Bangsan Market above the stairways. Climb up near Saebyeokdari and you surface at Gwangjang Market. Exit at Majeongyo and you are in Bangsan Market and Jungbu Market. Walk a little farther and it is Pyeonghwa Market and Dongdaemun.
Beodeuldari — the bridge that carries two names
The thirteenth bridge, Beodeuldari, originally took its name from the willows (beodeul) that once lined the stream bank. Since 2012, it has shared the name Jeon Tae-il Bridge. In 1970, near this spot in front of Pyeonghwa Market, a 22-year-old tailor named Jeon Tae-il set himself on fire to demand enforcement of the Labor Standards Act — an event widely regarded as the starting point of South Korea’s labor movement. His statue now stands on the bridge, and the deck is inlaid with bronze plaques bearing the names of citizens who contributed to the memorial. This is not a stop on the usual tourist circuit, but it is the place that explains, in the fewest possible words, what Cheonggyecheon was during the industrial era.
Ogansugyo — five sluice gates beneath the city wall
Beside the fourteenth bridge, a stone arch structure has been reconstructed. This marks the spot where the old Seoul City Wall crossed Cheonggyecheon. To let water out but keep people from sneaking through, the authorities built five sluice gates — the Oganusumun (Five-Water Gate) — and fitted them with iron bars. The Joseon royal annals record more than a few characters who pried those bars open to slip in and out of the capital. Climb the stairs here and you emerge right at Heunginjimun (Dongdaemun) and DDP.
If you stop here
Ogansugyo sits at the 2.86-km mark — almost exactly halfway through the 5.84-km restored stretch. Climb up and Dongdaemun, Gwangjang Market, and DDP are all within a 300-meter radius. If finishing the full walk is not your goal, this is the best place to call it and slide into an evening plan.
Downstream — Malgeunnaedari to Gosanja-gyo (2.6 km)
After Ogansugyo, the crowds thin out noticeably and the gaps between bridges widen. Where bridges upstream appear every 150 to 200 meters, down here they are spaced 300 to 440 meters apart. The sound of the water gets louder. The path broadens. Joggers and cyclists multiply. You have left the sightseeing zone and entered the neighborhood stream.
🏘️ What You'll Find Downstream
| Spot | What It Is | Notes |
|---|---|---|
| Preserved Expressway Piers | Three support columns of the old Cheonggye Expressway, left standing | Between Biudanggyo and Muhakgyo. Physical proof that a highway once ran directly above the stream |
| Shantytown Theme Zone | A reconstructed cluster of the makeshift houses that lined the stream from the 1950s to the 1970s | 10:00–18:00, closed Mondays |
| Cheonggyecheon Museum | A permanent exhibition covering the full arc of the stream’s covering and restoration | 09:00–18:00, closed Mondays, free admission |
| Biudanggyo | The longest of the 22 bridges at 46.6 m | A tunnel fountain runs beneath the bridge deck |
| Dumuldari | A footbridge at the confluence with Jeongneungcheon | The very first of the 22 to open (May 2004) |
The Cheonggyecheon Museum does not merely celebrate the restoration. It displays everyday objects from the shantytown years, engineering blueprints from the expressway era, and even the arguments made against the restoration project. Walk the five kilometers first, then step inside — the things you have just passed rearrange themselves into a coherent story. The location fits perfectly, too: it sits between Dumuldari and Gosanja-gyo, so if you walk the full route, you reach it naturally at the end.
So where does it actually end?
The last bridge is Gosanja-gyo, 5.53 km from Cheonggye Plaza. It is named after the pen name of Kim Jeong-ho, the 19th-century cartographer who made the Daedongyeojido — the most detailed map of Korea ever produced before modern surveying. Walk another 307 meters past this bridge and you reach the Sindap Railway Bridge, the official terminus of the restored section.
But the path does not end. Cheonggyecheon soon merges with the Jungnangcheon, and the pedestrian and bike trails along both waterways continue uninterrupted. The Seoul Facilities Corporation’s third official walking course — the “Cheonggye Rest Path” — runs from Dumuldari all the way to Yongdap Interchange Bridge. If you want to keep going, you can follow the Jungnangcheon south to the Han River, or head upstream toward Salgoji Bridge. Beyond this point, though, you have crossed from tourism into the territory of running and cycling.

Things to know before you walk
- Avoid rainy days. When the water level rises, the pedestrian path gets closed. During summer downpours, sirens sound and you must evacuate immediately.
- May and June bring mayflies downstream. Large swarms of *Ephemera orientalis* hatch during this season. They don't bite, but you'll want to avoid the areas near lamps at dusk.
- Midsummer afternoons are hotter than you'd expect. A stream sounds cool, but there is not much shade. In July and August, go after sunset — it is vastly better, and that is also when the night lighting comes on.
- Restrooms are above ground, near the bridges. There are almost none along the stream bank itself. The areas around Ogansugyo and Dumuldari are comparatively easy to find.
- Stepping stones are one-way in practice. The stones are narrow; if someone is coming the other way, one of you has to step aside. The day after rain, they are slippery.
How to read Cheonggyecheon
Twenty years after its restoration, Cheonggyecheon still divides opinion. It is an artificial stream fed by Han River water. It is landscaping laid over a concrete bed. The displacement of the surrounding shopkeepers during the restoration remains a live controversy. On the other side of the ledger: it lowered downtown temperatures, and it gave the city back the experience of crossing through its own center on foot.
What matters to a traveler is not which side is right, but that these 5.8 kilometers are the most compressed portrait of how Seoul has treated itself across six centuries. Stones from a queen’s tomb become bridge footings. Shacks rise on top of them. An expressway is laid over the shacks. The expressway is torn out and water is poured back in. Six hundred years, stacked a few flights of stairs below the street.
