October 17, 2026 – October 25, 2026

Seoul's autumn river festival — the Hangang Festival — runs from October 17 to 25, 2026 on the river and across seven Hangang parks — Jamwon, Gangseo, Ttukseom, Banpo, Yeouido, Nanji and Gwangnaru. Training sessions, riverside food, outdoor music and nature classes. ON Stage at Jamwon (Oct 17–18) is free to watch with no booking; some other programmes need advance reservation at seoul.go.kr/festa/hangang.

Seven riverside parks, one festival

The Hangang Festival returns for its autumn season from October 17 to 25, 2026, spread across the river itself and seven Hangang parks — Jamwon, Gangseo, Ttukseom, Banpo, Yeouido, Nanji and Gwangnaru. The Seoul city theme for this edition translates roughly as “look after both body and mind”, and the programme is built around moving: training sessions, food, outdoor music and nature classes along the water.

Practical

Bookings and programme details are on the official festival site: seoul.go.kr/festa/hangang. Some programmes need advance reservation and may fill up; ON Stage is free to watch on the spot, so there is always something you can simply walk into.

Fees for the individual booked programmes are not stated in the city announcement — check the official site before you go. The parks are large and spread along both banks, so pick one park and stay there rather than trying to cross between them in a day.
