South Korea itineraries: 1 week, 2 weeks and 3 weeks

Pick the length first, then the season, then the budget. The table below is the short version of everything on this page; the sections after it explain each route stop by stop.

Costs are 2026 estimates for one person travelling mid-range: a private room or good hostel, KTX and intercity buses, one paid attraction most days and two restaurant meals a day. Flights to and from South Korea are not included.

Start with the transport spine, not the sight list. One KTX line runs Seoul – Daejeon – Daegu – Gyeongju – Busan, so anything on that line costs you almost no travel time. Jeju is a flight from Gimpo or Busan, and the east coast (Gangneung, Sokcho) is a separate bus or train leg from Seoul.

For a first trip, four nights in Seoul is the minimum that covers the palaces, a market, a neighbourhood evening and one day out. Busan needs three nights to justify the trip: beaches, a seafood market, Gamcheon and one temple or coastal walk. Gyeongju works as one or two nights between Seoul and Busan, and Jeonju is a 1 h 40 KTX ride from Seoul that fits a single night.

Build in one slower day for every four moving days. South Korea is compact, but packing a new city into every morning is how people end up remembering only train stations.

Days 1–4, Seoul. Land at Incheon (ICN), take the AREX train into the city and stay in Myeongdong or Hongdae. Give one day to Gyeongbokgung, Bukchon and Insadong; one to a market and a neighbourhood such as Ikseondong or Seongsu; one to a day trip — Suwon's Hwaseong Fortress is an easy half day, the DMZ is a full one; and keep the last morning free for anything you missed.

Day 5, Seoul to Busan by KTX. Trains run roughly every 20–30 minutes and take about 2 h 30–3 h (check). Book a seat in advance for Friday, Sunday and holiday travel. Stay near Seomyeon or Haeundae.

Days 5–7, Busan. One day for Gamcheon village and Jagalchi seafood market, one for Haeundae beach and a coastal walk or temple, and a half day for whatever the weather allows. Fly out of Busan (PUS) if you can, or take the ferry to Fukuoka to continue in Japan.

The 14-day version keeps the same spine and adds Jeju. Seoul 5 nights, Gyeongju 2, Busan 3, Jeju 4, then fly back to Gimpo for the last night or connect straight to Incheon for the flight home.

Gyeongju is the Silla capital: tomb mounds, Cheomseongdae, Bulguksa and Seokguram, best seen by bicycle. Two nights let you do the historic core one day and the mountains the next.

On Jeju, rent a car at the airport — buses exist but eat the day. Base one or two nights in Jeju City and the rest in Seogwipo, and plan around Hallasan, the crater cones and one Olle trail rather than trying to circle the island every day. Book the car and the Gimpo–Jeju flights early in peak season (check).

With 21 days you can keep the 14-day route and add two regions that most one-week trips miss. Add two nights in Sokcho for Seoraksan National Park and the east-coast beaches, reached by bus or train from Seoul; and two nights in Tongyeong on the south coast for islands, a cable car and seafood, reachable from Busan.

Keep two or three nights in Seoul at the end. It is the easiest place to fly home from, and it absorbs a weather day or a missed connection without wrecking the trip.

If you would rather go slower, cut Jeju and give the extra nights to Gangwon and the south coast. Both are cheaper than Jeju in peak season and need no car.

Do not try to see the whole country in a week. The single most common planning error is adding Jeju to a 7-day trip; the flights and the car hire eat two days and you see less of Seoul and Busan.

Check the calendar before you book. Chuseok and Lunar New Year move every year and close many businesses; cherry-blossom season (late March to mid-April) and autumn leaves (late October to early November) fill Seoul hotels and KTX seats weeks ahead (check). Summer is hot and wet, and winter is cold enough to change what you can do outdoors.

Buy a T-money card for buses and the subway in Seoul and Busan, and keep some cash for markets and small restaurants. Tipping is not expected.
