Han River Swimming Pools Open at Night Until 10 PM: 2026 Visitor Guide

Han River swimming pool night openings are now part of Seoul’s 2026 summer program, giving evening visitors a structured alternative to a standard Han River Night Picnic. From July 3 to August 30, selected Han River swimming pools and water playgrounds operate until 10 p.m., while the full 2026 season runs from June 19 to August 30 across six riverside facilities. ¹

The night opening applies to four locations: Ttukseom Swimming Pool, Yeouido Swimming Pool, Jamsil Water Playground, and Nanji Water Playground. Gwangnaru Water Playground and Yanghwa Water Playground remain daytime-only facilities, closing at 6 p.m. ²

Han River Swimming Pool Night Opening: Dates and Locations

For 2026, Seoul operates two outdoor swimming pools and four water playgrounds along the Han River: Ttukseom and Yeouido as swimming pools, plus Jamsil, Gwangnaru, Nanji, and Yanghwa as water playgrounds. The city announced a 73-day operating period from June 19 through August 30. ¹

The key date for night visitors is July 3. From that date, Ttukseom, Yeouido, Jamsil, and Nanji stay open until 10 p.m., making them the relevant choices for anyone planning an evening swim or a cooler riverside outing after work. Gwangnaru and Yanghwa are still part of the 2026 program, but they are not part of the late-night schedule and operate only until 6 p.m. ¹

This distinction matters for planning. If the goal is a water-based evening plan, do not simply search for the nearest Han River pool and assume it has night hours. Choose one of the four late-opening sites first, then check the Seoul Future Han River Headquarters event page before leaving, because operations can be suspended during typhoons, heavy rain, fine dust warnings, or other severe weather conditions. ²

Jamsil Swimming Pool is not listed as a standard pool this season; the Jamsil location appears in the 2026 program as a water playground. Jamwon Swimming Pool is not operating in 2026 because of construction for a nature-style water playground. ¹

Prices, Discounts, and What to Check Before Going

Admission prices differ depending on whether you visit a swimming pool or a water playground. For swimming pools, the listed fees are 3,000 won for children, 4,000 won for teenagers, and 5,000 won for adults. For water playgrounds, the fees are 1,000 won for children, 2,000 won for teenagers, and 3,000 won for adults. Children under six are admitted free, and some eligible visitors can receive a 50% discount with supporting documents. ³

Because the night program runs into the evening, visitors should plan around more than just the ticket price. The available source material confirms late operation until 10 p.m. at the four participating locations, but it does not provide separate night-only ticket rules, entry cutoff times, refund rules, locker availability, or food policies. Treat those details as items to confirm directly through the official Seoul Future Han River Headquarters information page before visiting. ²

Safety and water quality are also part of the 2026 operating plan. Korea’s Hankook Ilbo reported that Seoul planned to place 138 CCTV cameras and 58 safety personnel for management, along with water quality inspections. ⁴ That does not remove the need for basic visitor judgment, especially at night: check the weather, choose a site with confirmed night hours, and allow enough travel time so the visit is not compressed near closing.

The night opening is not a one-off experiment. Yonhap News reported that 552,003 people visited Han River swimming pools and water playgrounds the previous year, a 77% increase from the year before, and that Seoul expanded night operations after favorable responses to the past two years of trial night openings. ⁵ In a YTN radio interview, Yoo Hye-mi, a Seoul Future Han River Headquarters parks official, said visitors can “enjoy night swimming and water play until 10 p.m.” at the participating sites. ⁶

How to Choose the Right Site for an Evening Visit

Start with the schedule. If the visit must happen after sunset or after work, narrow the list to Ttukseom, Yeouido, Jamsil, or Nanji. If daytime hours are enough, Gwangnaru and Yanghwa remain options, but they are not late-night choices in the 2026 plan. ²

Next, match the facility type to the group. The source material identifies Ttukseom and Yeouido as swimming pools, while Jamsil, Gwangnaru, Nanji, and Yanghwa are water playgrounds. That distinction also affects the published admission price, with water playgrounds costing less than swimming pools across child, teen, and adult categories. ³

Finally, build the visit around official operating status rather than assumption. The 2026 season runs through August 30, but weather and environmental conditions can interrupt operations. The most practical pre-departure check is whether the chosen location is open that day, whether night operation is still active, and whether any weather-related notice has been posted. ²
