Free Palaces, an Empty City and Sleepless Dongdaemun—With Zero Reservations! Chuseok Seoul in Three Days (24–27 Sept)
Holiday Seoul comes with three bonuses: palaces that open free, a city that empties out, and a Dongdaemun that never sleeps. Here’s the thing—you don’t need a single booking. Any three days of 24–27 September work, and the rain substitutes are attached.
