Han River Night Pools 2026: Where to Swim Until 10 PM in Seoul

The 2026 Han River night pool season gives Seoul visitors and residents a practical way to cool down after sunset. For anyone planning Han River Nights around an outdoor swim, the key point is simple: only four of the six Han River pool and water-play sites operate until 10 PM, and the night schedule runs from July 3 to August 30, 2026.¹

Seoul opened the 2026 Han River swimming pool and water-play season on June 19, with operations continuing through August 30. The late-night extension applies to Ttukseom Swimming Pool, Yeouido Swimming Pool, Jamsil Water Playground, and Nanji Water Playground, while Gwangnaru and Yanghwa remain daytime-only sites.²

Han River Night Pools: Dates, Hours, and Locations

Han River night pool Seoul open until 10 PM

The overall 2026 Han River pool season runs for 73 days, from June 19 to August 30. Standard daytime hours are 9 AM to 6 PM, and night operations run from 6 PM to 10 PM where available.³ Because July 10, 2026 falls within the night-opening period, the evening schedule is already in effect at the participating sites.

For night swimming, focus on these four locations: Ttukseom Swimming Pool, Yeouido Swimming Pool, Jamsil Water Playground, and Nanji Water Playground. These are the sites listed for extended operations until 10 PM from July 3 through August 30. Gwangnaru Water Playground and Yanghwa Water Playground are part of the broader six-site summer opening, but they close at 6 PM and do not offer the night schedule.²

The Seoul Metropolitan Government framed the extended hours as a way to escape both heat and tropical nights, using the phrase “Escape the heat, escape tropical nights!! Night opening until 22:00” in its announcement.¹ In practical terms, that makes the evening window most useful for people who want an after-work swim, a cooler family outing, or a late summer stop near the river without committing to a full daytime visit.

There is one important exception for regular Han River pool users: Jamwon Swimming Pool is not part of the 2026 opening. The Seoul Metropolitan Government Future Han River Headquarters states that Jamwon is expected to reopen after 2028 because of construction for a nature-style water playground.³

What to Know Before You Go

Admission prices differ between swimming pools and water playgrounds. For swimming pools, the listed fees are 5,000 won for adults, 4,000 won for teenagers, and 3,000 won for children. For water playgrounds, the fees are 3,000 won for adults, 2,000 won for teenagers, and 1,000 won for children.⁴

The two night-opening swimming pools are Ttukseom and Yeouido, while Jamsil and Nanji are water playgrounds. That distinction matters for both the price and the experience. The source material does not provide detailed facility-by-facility pool features, so the most reliable planning method is to choose first by operating hours and location, then by whether your group wants a swimming pool or a water-play area.

Some basic amenities are included. A Seoul city media report notes that showers, changing rooms, and parasols for groups of four are free. It also states that swimming is paused for 15 minutes every hour, and that entry into the water is prohibited during lunch and dinner periods.⁵ Those pauses are worth building into your schedule, especially if you are arriving in the evening and have only a few hours before closing.

Safety and hygiene are central to the official 2026 operation plan. Seoul said it would use 138 CCTV cameras, deploy 58 safety staff, and conduct daily water quality checks across the Han River swimming pool and water-play facilities.¹ These details do not remove the need for normal visitor caution, but they do clarify the city’s stated operating measures for the season.

Demand may be high. Yonhap reported that 552,003 people visited Han River outdoor swimming pools and water playgrounds the previous year, a 77 percent increase from the year before.⁶ For a smoother visit, the most practical approach is to confirm the site you want, check whether it is one of the four night-opening locations, and arrive with enough time to account for rest periods and evening crowding.

Planning an Evening Swim

A good evening plan starts with the location list. If your goal is to swim or play in the water after 6 PM, choose only Ttukseom, Yeouido, Jamsil, or Nanji. If you choose Gwangnaru or Yanghwa, plan for a daytime visit because both close at 6 PM.

Next, match the site type to your group. Adults or stronger swimmers may prefer one of the two swimming pools, while families with younger children may find the water playground format more convenient. The sources do not provide age-specific access rules beyond the listed fee categories, so visitors should rely on the official site notices at the venue for any detailed restrictions.

Finally, time the visit realistically. Night operations run from 6 PM to 10 PM, but the hourly 15-minute breaks and meal-period water restrictions can reduce actual swim time. Arriving earlier in the evening gives more flexibility than treating 10 PM as the only planning anchor.
