Every summer in Seoul, the Hangang River suddenly starts feeling different.
Pop-up ramyeon tables appear by the water, people carry tubes onto the subway, and the city’s public pools begin filling up again under the summer heat.
What surprised me most last year was not the atmosphere, though. It was the price.
When I visited Yeouido Hangang Pool last summer, I expected something far more ordinary. I expected an old public pool, a crowded entrance, and a slightly tired facility. Instead, what I remember most clearly is the view.
From inside the pool, the 63 Building rises behind the water, and the Hangang River stretches out just beyond the park. It did not feel like a resort, of course. But it felt unmistakably like Seoul in summer.
What made it feel even more surprising was how inexpensive it actually was. Regular Hangang swimming pools usually cost around 5,000 KRW for adults, while water playgrounds such as Jamsil, Nanji, and Yanghwa are usually around 3,000 KRW. For a city where even a simple cafe stop can cost more than that, the value is hard to ignore.
If you are planning a broader riverside day, you may also want to read my Hangang River Guide before choosing which park to visit.
For 2026, Seoul’s Hangang swimming pools and water playgrounds are expected to open around June and run through late August. But there are a few important changes this year. Jamwon Pool is closed for redevelopment, Mangwon Pool remains unavailable due to the Seongsan Bridge improvement project, and Gwangnaru should be checked again right before opening because its transition into a natural-style water playground has been under discussion.
Another point many people misunderstand is the operating time. Hangang pools are not automatically open until 10 PM for the entire season. The basic operating hours are usually from 9 AM to 6 PM, while night openings until 10 PM are limited to selected peak-summer periods.

What Changed for Hangang Pools in 2026?
The biggest change for 2026 is Jamwon Hangang Pool.
Jamwon is not simply “closed” in the casual sense. It is entering a redevelopment period from 2026 to 2027, with the city aiming to reopen it after 2028 as a greener riverside water space.
Mangwon Pool is also not operating, as its closure is connected to the Seongsan Bridge improvement project.
Gwangnaru is the one to watch carefully. Its transition into a more eco-friendly riverside water space has been discussed, so the safest thing to do is to check the official Future Hangang Headquarters notice right before the season begins.
The operating rules also matter more than you might expect. Based on previous seasons, visitors should be prepared for hourly rest breaks, possible entry restrictions during lunch or dinner cleaning periods, no alcohol, and required guardian supervision for young children.
- Hourly rest breaks are usually operated.
- Alcohol is not allowed inside the pool area.
- Swimming after drinking is strictly restricted.
- Young children must enter with a guardian.
- Operations may stop suddenly during heavy rain or flood-risk conditions.
Which Hangang Pool Should You Visit?
Hangang water facilities are divided into two main types: swimming pools and water playgrounds.
Yeouido and Ttukseom are closer to traditional outdoor swimming pools, with deeper water and a more active summer atmosphere. Jamsil, Nanji, and Yanghwa are more like casual water playgrounds, with shallower water and a softer family-friendly mood.
| Type | Place | Adult Fee | Highlight | Subway Access | Best For |
|---|---|---|---|---|---|
| Swimming Pool | Yeouido | 5,000 KRW | A dramatic Hangang view with the 63 Building in the background | Yeouinaru Station (Line 5) | River views and photos |
| Swimming Pool | Ttukseom | 5,000 KRW | Lazy river, sunbathing mood, and a lively summer crowd | Jayang (Ttukseom Hangang Park) Station (Line 7) | Friends and couples |
| Water Playground | Jamsil | 3,000 KRW | Natural lake and artificial beach atmosphere | Jamsilsaenae Station (Line 2) | Families with children |
| Water Playground | Nanji | 3,000 KRW | Open riverside mood close to the Hangang | World Cup Stadium Station (Line 6) | A slightly calmer atmosphere |
| Water Playground | Yanghwa | 3,000 KRW | Smaller, softer, and easier with young children | Seonyudo Station (Line 9) | Families with little kids |

Yeouido was the most memorable for me because of the view. The pool itself is simple, but when you look up and see the 63 Building and the river behind it, the whole place suddenly feels more special.

Jamsil felt much calmer. Because of its softer lagoon-style layout, it felt easier for children and better for a slower family afternoon.
Ttukseom had the most energy. It was lively, crowded, and closer to the mood of a summer festival inside the city.
Hours, Fees, and Subway Access
The basic operating hours are usually from 9 AM to 6 PM.
During selected peak-summer periods, night opening may extend the hours until 10 PM. But this does not apply to the entire season, so checking the official notice before visiting is important.
Swimming Pool Fees
- Adults: 5,000 KRW
- Teenagers: 4,000 KRW
- Children: 3,000 KRW
Water Playground Fees
- Adults: 3,000 KRW
- Teenagers: 2,000 KRW
- Children: 1,000 KRW
Children under the age of six are usually admitted free, and discounts may apply for eligible visitors such as holders of the Dadungi Happiness Card (Seoul’s multi-child family discount card) or seniors aged 65 and older.
For most visitors, subway access is easier than driving.
- Yeouido: Yeouinaru Station (Line 5)
- Ttukseom: Jayang (Ttukseom Hangang Park) Station (Line 7)
- Jamsil: Jamsilsaenae Station (Line 2) or Jamsil Station
- Nanji: World Cup Stadium Station (Line 6)
- Yanghwa: Seonyudo Station (Line 9) or Dangsan Station
If this is your first time using Seoul public transportation, check my T-money Card Guide before heading to the river.
From my experience, weekend parking can be stressful, especially at Ttukseom and Yeouido between early afternoon and late afternoon. If possible, I would choose a weekday morning and arrive by subway.
Jamwon Closure and Gwangnaru Reopening Status
Jamwon Hangang Pool will not operate during the 2026–2027 redevelopment period.
This is not just a temporary seasonal closure. The area is being redesigned into a greener riverside water space, with reopening expected after 2028.
Mangwon Pool is also not available because of the Seongsan Bridge improvement project.
Gwangnaru remains the most uncertain. Because the space may transition into a more eco-friendly riverside facility, the final 2026 operation status should be checked through the official Future Hangang Headquarters notice right before opening.
What to Bring to a Hangang Pool
The one item I would never skip is aqua shoes.
The ground gets extremely hot in summer, and walking barefoot between the pool, shower area, and resting space can become uncomfortable very quickly. Flip-flops help, but aqua shoes feel much more practical once you are actually moving around.
Another item many people forget is a swimming cap.
Even if you wear a regular cap, many pools still require a proper swimming cap underneath before entering the water. Buying one on-site is possible in some cases, but it is usually better to bring your own.
- Rash guard or swimsuit
- Swimming cap
- Aqua shoes
- Waterproof pouch
- Towel
- Sunscreen
- Ice tumbler or reusable cup
- Portable fan
A reusable cup or ice tumbler is more useful than it sounds. Cold water stays cold much longer, and during the hottest hours of the day, that small detail makes a real difference.
Honest Tips from Last Summer
The biggest difference I felt last summer was between Ttukseom and Jamsil.
Ttukseom was much more energetic. The park is wide, the pool atmosphere is livelier, and it feels closer to a city summer festival. It is fun, but it also gets crowded quickly.
Jamsil felt slower and more relaxed. Because of its gentler layout and shallow water zones, it was easier for children to get used to the water, and the overall mood felt calmer.
One thing many first-time visitors do not realize is that good shade is limited.
Shade tents are often restricted, so if you want one of the free parasol spots, arriving early matters. During peak summer, I would aim to arrive at least 20 to 30 minutes before the 9 AM opening time. Last summer, there were already people waiting before opening.
Re-entry may be possible if you receive an outside stamp, which can be useful when visiting a nearby convenience store. Homemade lunch boxes and fruit are generally easier to bring than delivery food, but alcohol is not allowed.
Pool users may also be eligible for a parking discount stamp, so check before leaving if you drove there.
And after swimming, instant ramyeon from a Hangang convenience store somehow tastes better than usual.
There is something very Seoul about eating hot ramyeon after getting out of the water, still a little wet, with the river nearby and summer heat hanging in the air.
Seoul summer always feels shorter than expected.
Maybe that is why Hangang pools feel so seasonal. When they open again, it feels like the city has officially entered summer.
