Outdoor Swimming Pools Seoul: Han River Lap Lanes Open

Seoul Metropolitan Government opened seasonal lap lanes at three Han River park sites on June 15, giving residents direct access to measured 50-metre courses without indoor facility fees.

The move comes as average July temperatures in the capital have climbed above 31 degrees Celsius for the past five summers, prompting more residents to shift morning and evening workouts outdoors rather than rely on air-conditioned gyms in Gangnam or Jongno.

Yeouido Hangang Park maintains eight roped lanes between 6 a.m. and 8 p.m., while the Banpo section of the same riverfront added four additional lanes this month after last year’s overcrowding complaints. Swimmers pay 6,000 won for a three-hour session, with monthly passes available through the city’s Sports Facility Reservation System.

Rock pools near Bukhansan trails

Further north, the natural rock pools at the Dobong-gu entrance to Bukhansan National Park provide an alternative for those who prefer current-assisted intervals. The largest basin measures roughly 25 metres end to end and stays shaded until mid-morning, allowing consistent lap counts even on peak summer days. Local running clubs based at the nearby Dobong Station community centre schedule group swims twice weekly.

City data released last month showed 187,400 visits to Han River outdoor pools between June and September 2025, a 22 percent rise from the previous year. Officials attribute the increase to extended operating hours and the addition of shaded changing areas at Yeouido and Ttukseom.

Swimmers planning a session this weekend should reserve spots online by 10 p.m. the night before, as same-day capacity at both river and mountain sites fills quickly once temperatures exceed 30 degrees. Those heading to Bukhansan are advised to carry water shoes for the rocky entry points and to check the park’s daily water-quality bulletin posted at the trailhead kiosk.
