Hangang night swimming pools are operating for the 2026 summer season, with selected riverside facilities open late from July 3 through August 30. For anyone planning a Hangang Night Picnic with swimming or water play, the most important detail is that only four of the six open facilities run until 10 p.m. during the night-opening period.1
The 2026 Hangang water program includes two outdoor swimming pools and four water play areas. Ttukseom Swimming Pool, Yeouido Swimming Pool, Jamsil Water Play Area, and Nanji Water Play Area are the late-night options, while Gwangnaru Water Play Area and Yanghwa Water Play Area close at 6 p.m.12
Hangang Night Swimming Pools: 2026 Dates and Hours
The full 2026 operating season runs from June 19 to August 30, covering 73 days at six Hangang Park water facilities.1 The open sites are Ttukseom Swimming Pool, Yeouido Swimming Pool, Jamsil Water Play Area, Gwangnaru Water Play Area, Nanji Water Play Area, and Yanghwa Water Play Area.3
Night operation applies from July 3 to August 30 at Ttukseom, Yeouido, Jamsil, and Nanji. During that period, those four sites operate from 9 a.m. to 10 p.m., making them the practical choices for evening swimming or water play.2 Gwangnaru and Yanghwa are still part of the summer lineup, but they are not late-night facilities because they operate only until 6 p.m.1
Jamwon Swimming Pool is not included in the 2026 operating list. The official Hangang notice says Jamwon is closed because of remodeling work, while a separate Seoul announcement describes the non-operation as connected to the creation of a nature-style water play area.43 Readers who previously used Jamwon should choose another site for the 2026 season.
For a night-focused visit, the decision is straightforward. Choose Ttukseom or Yeouido if you want one of the two listed swimming pool sites. Choose Jamsil or Nanji if a water play area fits your plan and the 10 p.m. closing time matters. Choose Gwangnaru or Yanghwa only when your schedule ends before early evening.
Choosing the Right Hangang Pool or Water Play Area
Ttukseom and Yeouido are the two swimming pool locations in the 2026 program. Ttukseom is noted for a lazy-river-style pool, and Yeouido is presented as one of the main outdoor swimming pool sites along the river.5 These are the clearest choices if the priority is a more conventional pool outing.
Jamsil, Nanji, Gwangnaru, and Yanghwa are water play areas rather than full swimming pools. For night use, Jamsil and Nanji are the relevant options because both are included among the facilities open until 10 p.m. Jamsil is described with an infinity wall feature, and Nanji is described as a view-oriented water play area.5
Program information may also help visitors compare sites. Reported summer programs include night performances at Ttukseom, “Hangang Music Pongdang” at Nanji, and “Hangang Eolsu(水)! Pongdang” at Jamsil.5 The provided source material does not give a detailed daily timetable for each program, so visitors should treat the names as planning clues rather than confirmed schedules for every date.
For Jamsil, the official notice includes a specific access warning. Because the former Parking Lot 4 is closed, Jamsil visitors are directed to enter toward Parking Lot 1 and use Parking Lot 5.4 This is especially relevant for evening visits, when arriving with an outdated parking plan can waste time.
Fees, Booking, and Safety Notes
Admission prices differ by facility type. For swimming pools, the 2026 fees are 3,000 won for children, 4,000 won for teenagers, and 5,000 won for adults. For water play areas, the fees are 1,000 won for children, 2,000 won for teenagers, and 3,000 won for adults.1
The official Hangang Park swimming pool and water play page was updated on July 14, 2026, with online reservation guidance and facility-by-facility operating information.4 Because the source material confirms online reservation guidance but does not reproduce every booking step, the safest planning approach is to check the official Hangang page before going, especially for weekend or evening visits.
Safety and water quality management are also part of the 2026 operating plan. Seoul announced CCTV coverage, safety staffing, and regular water quality testing for the Hangang swimming pool and water play season, including 138 CCTV cameras and 58 safety personnel.3 Those details do not remove the need for normal supervision, but they confirm that safety management is part of the city’s published operating plan.
The scale of demand is worth noting for trip planning. The previous year’s Hangang pool and water play facilities drew 552,003 visitors, a 77% increase from the year before, and Seoul expanded night operation and experience programs for 2026.2 That visitor figure supports a practical point: evening slots at the most convenient sites may be busy, so checking reservation information and transportation plans in advance is sensible.
