Absolute Asia/South Korea/South Korea Itinerary: 10 Days Across Seoul, Gyeongju and Busan
South Korea Itinerary: 10 Days Across Seoul, Gyeongju and Busan
A 10-day South Korea itinerary: Seoul palaces, Gyeongju’s UNESCO sites and Busan, with the KTX times, K-ETA exemption rules for 2026 and how to add Jeju or the DMZ.

Quick Overview: A 10-day South Korea itinerary: Seoul palaces, Gyeongju’s UNESCO sites and Busan, with the KTX times, K-ETA exemption rules for 2026 and how to add Jeju or the DMZ.
Ten days is the right length for a first South Korea trip: four nights in Seoul, two in Gyeongju, three in Busan, and a flight home from either Busan or Seoul. The KTX high-speed train links the three in a couple of hours each, so most of your days go to palaces, temples and food, not to travel. Add Jeju or the DMZ only if you have days to spare.

Seoul: four nights
Gyeongbokgung was inaugurated in 1395, and Changdeokgung is a UNESCO World Heritage Site (1997). Do both palaces on separate mornings, since each needs a couple of hours. Spend afternoons in Bukchon’s hanok streets and the evenings at markets. Our things to do in Seoul guide has the full list. For the DMZ, which is a border zone 238 km long, most visitors take a half-day tour; confirm booking and ID requirements with the operator.
Gyeongju: two nights
Gyeongju was the capital of the Silla kingdom, and it has two UNESCO listings: Bulguksa temple with the Seokguram grotto (1995), and the Gyeongju Historic Areas. Take the KTX from Seoul to Gyeongju station, which sits west of the city center in Geoncheon-eup, then a taxi or bus into town. Two nights lets you see Bulguksa in the morning, before the tour groups arrive.

Busan: three nights
Busan is South Korea’s second-largest city, with a long beach at Haeundae, a working harbor and good seafood. Give it three nights to cover the coast, a temple and the fish market. Read our Busan page for more.

Adding Jeju
If you have two more days, fly to Jeju. The island has a UNESCO natural World Heritage Site, Jeju Volcanic Island and Lava Tubes (2007), and a subtropical climate. It’s an extra flight from Busan or Seoul, so only add it if you’d rather see volcanic scenery than more city time.
When to go
Spring and fall are the usual choices for a mainland itinerary. See our guides to autumn in South Korea and South Korea in winter for seasonal detail.
Entry rules for US citizens
US citizens are temporarily exempt from the K-ETA until 31 December 2026, according to Korean embassy notices, but the exemption has been renewed one year at a time and nothing has been announced for 2027. Without a K-ETA you still file the e-Arrival Card online. If your trip is in 2027, check the K-ETA portal before booking.
