Seoul will open six outdoor swimming pools and water playgrounds along the Han River starting Friday, offering residents and tourists a popular urban escape from the summer heat.

The facilities — located at Ttukseom, Yeouido, Jamsil, Gwangnaru, Nanji and Yanghwa parks — will operate through Aug. 30, according to the Seoul Metropolitan Government. The sites are part of the city's extensive Han River park system, a major recreational destination that stretches across the capital.

The city said more than 552,000 visitors used the facilities last year, a 77 percent increase from 2024, highlighting growing demand for affordable outdoor leisure activities in Seoul.

Most locations will operate daily from 9 a.m. to 6 p.m., with extended evening hours until 10 p.m. from July 3 through Aug. 30 at selected venues, including Ttukseom, Yeouido, Jamsil and Nanji.
