Seonyudo Park is a riverside park on Seonyudo Island in Seoul, at 343 Seonyu-ro in Yeongdeungpo District. A former water-treatment site, it brings gardens, ponds and old industrial structures together along the Han River. Walk among the park’s planted areas and art installations, pause in the shade, and look out across the water. Small seating spots suit a picnic, and cafes and convenience stores nearby have snacks and drinks. The island is a quieter option for a riverside walk, especially on a weekday.
From water-treatment site to park

Seonyudo Park occupies an island in the Han River that was once used for water treatment. The site was converted into an ecological park, bringing planted areas into the industrial setting. That combination shapes the walk: old structures sit among greenery, and the grounds have a layered feel rather than one continuous lawn.
The park is at 343 Seonyu-ro in Yeongdeungpo District. Its island setting gives the paths views across the river, with the surrounding water part of the experience as you move between the gardens and structures.
Gardens, ponds and places to pause

The park includes gardens and ponds, as well as themed areas such as Time Park, green corners and vegetable nurseries. A greenhouse and floating gardens are also among its features. Art installations appear around the grounds, so allow time to notice the details as you walk rather than treating the visit as only a riverside viewpoint.
Benches and smaller seating areas under trees give you places to rest in the shade. They also suit a simple picnic. Cafes and convenience stores in or near the park provide snacks and drinks, though the park’s appeal is as much in the walk and quiet corners as in stopping to buy something.
Choosing a time to visit
Autumn brings changing foliage, while spring is a good choice for flowers and a picnic. A weekday can be a quieter time to explore than a busy riverside park. The park is also used for morning walks and jogging, and its evening setting appeals to people looking for a calm stroll.
Bring a camera if you want to photograph the gardens, structures and river views from different angles. Families can make use of the playground, which has slides, swings and climbing structures. Public restrooms are available in the park.
Getting onto the island
The island can be reached by Yanghwadaegyo Bridge or the pedestrian Rainbow Bridge. The park’s location in the Han River makes the approach part of the visit, with river views along the way. Check your route before setting out, especially if you are planning to connect the park with another stop on the river.
