One-day plan
Start around Cheonggyecheon and HiKR Ground for official visitor context, exhibitions, and K-culture orientation.
Move to Hongdae for music streets, shops, cafes, and a casual meal.
Go to Seongsu for pop-ups, design, cafes, and photo-friendly streets.
Finish in Myeongdong for beauty, personal color, album shopping, snacks, and a simple return to most hotels.
Current public event watch: Hangang Festival Summer 2026
Seoul's official Hangang Festival Summer runs August 1-16, 2026 across public Han River parks, giving K-pop and screen-culture fans a safe seasonal add-on instead of a private-location search. Official tourism listings describe water activities, outdoor movie screenings, concerts, music, dance, DJ performances, markets, and riverside rest areas.
For a Seoul fan itinerary, treat the festival as an evening option after Hongdae, Seongsu, or Myeongdong. Check the official festival schedule before going because programs are split across different Hangang parks and some events can change with weather.
