Is 9 days too long in Seoul for a first trip?
For most first trips, yes, if all nine days stay in Seoul. Wikivoyage says a casual traveler can see most of the main sites in a few days1. Our call: give Seoul four or five days and spend the rest on Busan, which a KTX train reaches in 120 to 150 minutes2.
What the city asks of you
Seoul is vast. A casual traveler can see most of the main sites in a few days, while a dedicated traveler could spend months in the alleys and far-off neighborhoods1. So the question is not whether Seoul has enough to do. It is how much of it you want.
If you stay all nine days
It works if you want a slow pace, one hotel, and several neighborhood days with no checklist. It does not work if you want to cross off the famous sights, because those fit in the first few days. Plan one area per day and leave a free half day for rest.
If you split the trip
Busan is roughly 450 km from Seoul3. The KTX takes 120 to 150 minutes and the economy fare is ₩59,8002. KTX reservations are mandatory, and the Seoul to Busan line can be full on weekends without booking at least a week ahead4.
A season check
Winters in Seoul can be very cold, with temperatures at times below −10 °C in January and February5. If you travel then, put fewer outdoor sights in each day.
