5 October travel briefing: Seongsu in Seoul, Haeundae in Busan, and weekend dates
Monday 5 October 2026 is the substitute holiday for National Foundation Day. We suggest one programme at the festival starting today in Seongsu, Seoul, or a Haeundae Beach and Dongbaekseom walk in Busan. Choose the option near your base; this is not a one-day trip connecting both cities.
