Mangwon Hangang Park to Seonyudo Park: An Easy Seoul River Walk

Yes, you can walk from Mangwon Hangang Park to Seonyudo Park, and it makes one of the easiest riverside walks in west Seoul. The route follows the north bank of the Han River to Yanghwa Bridge. You cross the bridge on its pedestrian sidewalk and come down onto Seonyudo, a small island park built on the site of an old water purification plant. Plan on about 1 to 1.5 hours one way at a relaxed pace, including photo stops. Then leave on the south side via the arched Seonyugyo footbridge toward Seonyudo Station or Dangsan. The route is flat, free and works in every season, though it's at its best in spring, autumn and around sunset.

Why this walk is worth it

Most visitors only see the Han River from Yeouido or Banpo. This route stays local. It starts in Mangwon, a neighborhood of small cafes and a much-loved traditional market. It ends on an island garden where concrete water tanks have been turned into planted courtyards. Along the way you get wide river views, joggers and cyclists, convenience stores with river-view seating, and one long bridge with the city opening up on both sides.

It's also easy to fit around other plans. Do it in the afternoon after a morning in Hongdae, or finish at Seonyudo for sunset and then head into Dangsan or Yeouido for dinner.

The route, step by step

1. Start at Mangwon Station or Mangwon Market

Mangwon Station is on Seoul Subway Line 6. If you're hungry, walk through Mangwon Market first and pick up snacks such as fried chicken pieces, croquettes or tteok to carry with you. For a longer food stop, our Mangwon-dong to Hapjeong food walk covers the neighborhood in more detail.

2. Walk down to Mangwon Hangang Park

From the station area, follow the signs for Mangwon Hangang Park (망원한강공원). Like most Han River parks, it's on the other side of the riverside expressway, so you reach it through a pedestrian underpass (tunnel) instead of crossing the road. The walk from the station takes roughly 15 minutes. Once you're through, you'll see open lawns, a river path, rental bike stations and convenience stores.

3. Head west (downstream) along the river path

With the river on your left, walk downstream toward Yanghwa Bridge (양화대교). Walkers and cyclists have separate lanes. Stay in the pedestrian lane and watch out for fast bikes, especially on weekends. This stretch is flat and open, with benches and views across to the south bank.

4. Cross Yanghwa Bridge

Get onto the bridge by following the signs for the pedestrian access to Yanghwa Bridge from the park. There are stairs and, at some access points, elevators. Use the sidewalk to cross toward the south side. Partway across, look for the way down onto Seonyudo. The island sits under and beside the bridge, and you reach it from the bridge itself. If you're unsure, a map app such as Naver Map or KakaoMap shows the access points clearly.

5. Explore Seonyudo Park

Seonyudo Park opened in the early 2000s on the site of a former water treatment plant. It's often described as Korea's first park built around recycled industrial structures. Old settling tanks, pillars and pipes have been kept and planted with water plants, vines and trees. The result feels part garden, part ruin. Highlights include:

  • The Water Garden and aquatic plant beds inside the old tanks.
  • The Garden of Green Pillars, where ivy-covered concrete columns stand in rows.
  • River viewpoints looking back toward Mangwon, Yeouido and the bridges.
  • Small exhibition spaces about the island's history. Their opening days can vary.

Give yourself 30–60 minutes on the island. It's small, but it rewards slow wandering.

6. Leave by Seonyugyo footbridge

Seonyugyo (선유교) is a pedestrian-only arched bridge that links the island to the south bank at Yanghwa Hangang Park. It's lit at night and is a popular sunset photo spot. From the south side, walk to Seonyudo Station (Line 9) or Dangsan Station (Lines 2 and 9) to continue your day.

Best time to go

  • Spring and autumn: The most comfortable weather. In autumn, the island's trees and grasses change color.
  • Summer: Go in the late afternoon. The river path has little shade, and Seonyudo has mosquitoes near the water gardens.
  • Winter: Still very walkable on a clear day, but the wind on Yanghwa Bridge is strong and cold. Dress in layers.
  • Sunset: Time your arrival on Seonyudo or Seonyugyo for the last hour of daylight. The views west over the river are lovely.

Seonyudo Park has set opening hours and closes at night. Check the Seoul Hangang Park or Visit Seoul pages for current hours before planning a late visit.

Variations

Bike instead of walk

Seoul's public bike, Ttareungyi (따릉이), has stations around Mangwon Hangang Park. Riding the north-bank bike path is quick. Be aware that some bridge access routes involve stairs or elevators, which are awkward with a bike.

Reverse the route

Start at Seonyudo Station or Dangsan, cross Seonyugyo onto the island, take Yanghwa Bridge to the north side, and finish with dinner in Mangwon. This version works well if you want to end at the market or in Hapjeong.

Add a free park nearby

If you still have energy, the Oil Tank Culture Park and World Cup Park sit a little further west on the north side. They're another good example of Seoul turning industrial sites into public space.

Quick tips

  • Use Mangwon Station (Line 6) to start and Seonyudo (Line 9) or Dangsan (Lines 2 and 9) to finish.
  • Pick up snacks at Mangwon Market. Seonyudo itself has few food options.
  • Stay in the pedestrian lane on the river path; the bikes are fast.
  • Bring a windproof layer for Yanghwa Bridge, even in spring.
  • Check Seonyudo Park's closing time if you plan to stay past sunset.
  • Use Naver Map or KakaoMap for the bridge access points. They're easier to read than signs.
