Chuseok. The harvest festival works like a second New Year: several days of hometown travel, closures at small shops, and festive palace programs.
Things to do in Seoul
- 1
Gyeongbokgung Palace. The grandest of the five palaces. Catch the changing of the guard, and note most palaces close one day a week (Gyeongbokgung on Tuesdays). official site ↗
- 2
Changdeokgung's Secret Garden. The UNESCO-listed rear garden is by guided entry with capped numbers; book ahead, especially for fall color.
- 3
Bukchon Hanok Village. Traditional homes on a hillside between the palaces. It is a residential neighborhood: go early, keep voices down, and the photos come easy.
- 4
Gwangjang Market. Bindaetteok pancakes, knife-cut noodles, and the famous fabric hall upstairs. Lunch here beats any food tour.
- 5
N Seoul Tower and the Namsan walk. Ride the cable car up, walk down through the park at dusk as the city lights come on. official site ↗
- 6
DMZ tour. The border with North Korea, about an hour out, visited on regulated tours that book out ahead. Sobering, strange, and singular.
- 7
Hongdae and Seongsu nightlife. Street performers and clubs in Hongdae, converted-warehouse cafes in Seongsu. Seoul's night energy is half the visit.
- 8
A jjimjilbang (Korean sauna). Multi-floor bathhouse culture: hot pools, ice rooms, sleeping halls, and sheep-towel hats. Best appreciated on a cold or rainy day.
Beat the crowds
- →See the palaces at 9am opening or in the last two hours; midday belongs to tour groups, and Bukchon's lanes are quietest before breakfast.
- →For cherry blossoms, walk Yeouido at sunrise or choose quieter stretches along the Han River tributaries over the festival core.
- →Never plan intercity travel during Seollal or Chuseok without tickets booked the moment they release; those are the country's two travel crushes.
Know before you go
- !Seollal and Chuseok (dates shift yearly on the lunar calendar) close many small restaurants and shops for two to four days while department stores shorten hours; major palaces and museums typically stay open with holiday programming.
- !Most royal palaces close one day a week (Gyeongbokgung on Tuesdays, most others on Mondays); pair your palace days accordingly.
- !The jangma monsoon (roughly late June through July) cancels outdoor plans without notice; Seoul's answer is an unmatched indoor bench of museums, malls, and saunas.
