Seoul's Han River Pools for About $3.50: The 6 Open in 2026, Night Hours, and the Rule That Gets You Turned Away

You've probably seen the clips: people floating on tubes in an open-air pool with Seoul's skyline and a river bridge right behind them. That's the Han River (Hangang) summer pools — and the videos never tell you which park it is, what it costs, or that one of the most-filmed locations isn't even open this year. Here's the practical version for a traveler: the six pools actually operating in 2026, prices in won and dollars, which ones stay open until 10 p.m., and the two rules that will get you turned away at the gate.

1. First, the basics: what a "Han River pool" actually is

Seoul's Han River parks are free public riverside parks that run through the middle of the city. Every summer the city opens outdoor pools and water-play areas inside several of them — municipal facilities, not resorts. There's no resort pricing either: a full adult ticket is 5,000 won (about US$3.70), and the cheaper sites are 3,000 won (about $2.20). For most travelers that's less than a coffee.

As of August 4, 2026, the season opened on June 19 and runs through August 30 — 73 days, with no regular closing days during that period. If your Seoul trip falls after August 30, these pools are closed for the year.

One trap to know up front: the Jamwon pool is not operating at all in 2026 because it's being rebuilt as a natural-style water park. Plenty of videos and blog posts from last year still point there.

2. The six locations, and how to reach them

Korean signage splits them into two categories — "swimming pools" (수영장) and "water-play areas" (물놀이장) — and that distinction decides your ticket price, so it's worth knowing.

Site	Type	District	Night hours
Ttukseom 뚝섬	Pool	Gwangjin-gu, Jayang-dong 112	Until 10 p.m.
Yeouido 여의도	Pool	Yeongdeungpo-gu, Yeouido-dong 82-9	Until 10 p.m.
Jamsil 잠실	Water-play	Songpa-gu, Jamsil-dong 1-1	Until 10 p.m.
Nanji 난지	Water-play	Mapo-gu, Sangam-dong 482-182	Until 10 p.m.
Gwangnaru 광나루	Water-play	Gangdong-gu, Cheonho-dong 351-1	None — closes 6 p.m.
Yanghwa 양화	Water-play	Yeongdeungpo-gu, Yanghwa-dong 1-4	None — closes 6 p.m.
Jamwon 잠원	—	—	Closed all of 2026 (construction)

If you're staying anywhere central, the two easiest by subway are Ttukseom Hangang Park (Ttukseom Resort Station, Line 7) and Yeouido Hangang Park (Yeouinaru Station, Line 5) — both put you in the park within a short walk of the exit. Those also happen to be the two full "pools," which matters for the next section.

Driving isn't the move on a summer weekend, but if you do: Seoul city guidance points visitors to Ttukseom Hangang Park Parking Lot No. 3 for Ttukseom, and Yeouido Hangang Park Parking Lot No. 3 or the National Assembly riverside lot for Yeouido. Both fill up early.

3. Prices — and why the cheaper sites aren't a downgrade

Type	Adult (19+)	Teen (13–18)	Child (6–12)
Pools Ttukseom, Yeouido	5,000 won (~$3.70)	4,000 won (~$2.95)	3,000 won (~$2.20)
Water-play areas Jamsil, Gwangnaru, Nanji, Yanghwa	3,000 won (~$2.20)	2,000 won (~$1.50)	1,000 won (~$0.75)

Dollar figures are approximate, at roughly 1,360 won to the dollar. Children under 6 enter free, and there's a 50% discount for visitors 65 and older, people with disabilities and their companion, national merit recipients, and holders of Korea's multi-child family card. Both the free entry and the discount require physical proof documents — a photo on your phone may not be accepted, and a foreign passport is the practical way to show a child's age.

One traveler-specific caveat: we could not verify whether ticket booths accept foreign-issued cards, and small municipal facilities in Korea are inconsistent about this. Carrying 10,000–20,000 won in cash removes the problem entirely.

If you're travelling with a small child, Gwangnaru is the newest option — rebuilt in April 2026 as a natural-style water park with a family pool, a toddler pool, and a shallow stream, with a maximum depth under 1 m. Jamsil and Gwangnaru also have family changing rooms, which is the detail that decides the day when you're wrangling a five-year-old. Per Seoul city coverage, Yeouido is the shallower of the two big pools, while Ttukseom is the largest and its free-swim pool gets deeper toward the far end.

4. Two rules that get foreign visitors turned away

These aren't small print. They're the reason people show up and don't get in.

Rule 1 — a swim cap is mandatory, and so is actual swimwear. Korean public pools require a swim cap on every swimmer regardless of hair length, and the Han River pools are no exception. Cotton pants or casual shorts won't be accepted as swimwear either. Guidance on cap styles reads slightly differently depending on the source, so the safe move is to bring a standard close-fitting swim cap (wearing a sun cap over it is described as allowed). If you didn't pack one, convenience stores and discount shops near the parks generally carry basic caps in summer.

Rule 2 — no delivery food. This one surprises people, because eating fried chicken delivered to a mat by the river is a genuine Seoul ritual — just not inside the pool gates. Delivery food is banned and getting caught can mean being asked to leave. The full banned list: alcohol, delivery food, glass bottles, gas burners, knives, whole uncut fruit, large tubes, fins and snorkels, kickboards and paddles, water guns, pop-up sun shelters, and pets. What you can bring: a small personal tube, a one-person mat, simple packed food in reusable containers, and drinks in a tumbler.

Worth separating out: large tubes are banned, but children entering the teen or adult pools must wear a life jacket or tube and be accompanied by a guardian. Kids' safety gear isn't just allowed — it's required.

5. Planning your visit: hours, shade, and weather

• Base hours are 9 a.m. to 6 p.m., extended to 10 p.m. from July 3 through August 30 at Ttukseom, Yeouido, Jamsil and Nanji. Those night sessions are when the skyline-and-bridge shots happen. Gwangnaru and Yanghwa don't extend — they close at 6 p.m.
• Budget more time than you think. There's a 15-minute break every hour when nobody's in the water, plus no-swim periods from 12–1 p.m. and 6–7 p.m. Seoul's own coverage describes it as 45 minutes swimming, 15 minutes out. A two-hour visit gives you noticeably less than two hours of swimming.
• Arrive before noon if you want shade. Parasols are provided on site free, first come first served, and they're mostly taken once midday passes.
• Check the day's status before you travel across the city. Heavy rain and typhoons can cause a temporary suspension due to flooding risk — the Han River parks sit right on the water. August is the rainy end of the season.
• Pack: swimsuit, swim cap, towel, sunscreen, 10,000–20,000 won cash, and a reusable container if you want to bring food. Leave the water gun and the big flamingo float at home.

6. What we couldn't confirm

A few details circulate widely but we couldn't verify them against an official source, so treat them as unconfirmed rather than fact: the paid sun-lounger fee (one aggregator lists 10,000 won, but availability differs by site), the re-entry policy (some summaries say leaving means you can't return, with a five-minute grace period), locker fees (described as charged, with availability varying by park), and whether any season pass exists in 2026. We also could not confirm in real time that all six sites are operating today — the dates above are the announced season, so check the facility on the day you go.

Short version: the Han River pools are one of the cheapest genuinely local things you can do in Seoul in summer — about $2 to $4, open until 10 p.m. at four of the six sites, and finished for the year on August 30, 2026. Bring a swim cap, skip Jamwon, and don't order delivery to the gate. Save this for your trip planning, and if you make it to one of them, tell us in the comments which site you picked — it helps the next person deciding between Ttukseom and Yeouido.
