7 days in Seoul and Busan: an itinerary that doesn't waste time
Four days in Seoul, a two-hour train, three days by the sea. The trick is doing Busan by area and not dragging your suitcase across it.
Quick answer
- Split: four days in Seoul, three in Busan. Take the KTX south on the morning of day five.
- The train: Seoul to Busan standard class is about 54,000 won since September 1, 2026, and the fastest trains take a little over two hours.
- Busan by area: one day for Haeundae and Gwangalli, one for Nampo-dong, Jagalchi and Gamcheon.
- Transit cards: your T-money card works in Busan. The Climate Card doesn't.
- Fly home from Busan if you can: it saves a half-day trip back to Incheon.
- KTX Seoul to Busan
- About 54,000 won standard (from Sept 2026)
- Fastest KTX
- About 2 hours 10 minutes
- Busan subway
- 1,600 won by card, short trips
- Climate Card in Busan
- Doesn't work; T-money does
A week in Korea is the point where most people want a second city, and Busan is the obvious one: a fast train away, on the sea, and different enough from Seoul to feel like a separate trip. The risk is that you spend that week packing, checking out, hauling bags across two cities and doubling back to Incheon at the end. With a bit of order, you lose half a day to travel in total, not two.
The short version
Spend days one to four in Seoul, take a morning KTX to Busan on day five, and spend days five to seven there. Do Busan in two areas, the beaches in the east and the old downtown in the south, rather than bouncing between them. If your airline lets you, fly home from Busan’s Gimhae Airport instead of going back to Incheon. Your T-money card comes with you. The Climate Card stays in Seoul.
Days 1 to 4 in Seoul
For the first three days, follow our 3-day Seoul itinerary: the palaces and Bukchon on one day, Namdaemun, Myeongdong and Namsan on the next, Hongdae, Mangwon and the Han River on the third. It’s grouped by neighborhood so you’re not crossing the city twice a day.
Two rules from that plan matter for the whole week. Gyeongbokgung is closed on Tuesdays, so don’t schedule your palace day then. And Bukchon’s main lane is open to tourists only from 10 a.m. to 5 p.m. Palace entry is 3,000 won for adults (free in hanbok), with new fees due from January 1, 2027.
Day four is your flexible day. Good options:
- A day trip. Suwon’s fortress walls or the DMZ are the two most popular. Book a DMZ tour a few days ahead.
- Seongsu and Seoul Forest. Warehouse cafes, pop-up shops and a big park on the east side.
- A rest day. Seriously. A week is long, and the KTX is easier when you’re not wrecked.
Pack the night before. You want to be on the train mid-morning.
Day 5 on the KTX to Busan
Most KTX trains to Busan leave from Seoul Station. If you’re staying in Gangnam, Suseo Station is closer, and since Korail and SR combined operations in September 2026, both stations sell through one app, Korail+.
Since September 1, 2026, a standard adult seat from Seoul to Busan costs about 54,000 won, down from 59,800 won (reports put the new fare at 53,820 or 54,400 won depending on the departure station, so check the app). The cut is part of the merger and is meant to last three years. The fastest trains take around 2 hours and 10 minutes. Trains with more stops take longer, so check the time when you book, not just the price.
Book ahead for weekends and holidays. Our KTX booking guide covers how to do it with a foreign card.
Arrive in Busan around lunchtime, drop your bags, and spend the afternoon in whichever area your hotel is in.
Days 5 to 7 in Busan, area by area
Busan is long and hilly, and the sights are spread along the coast. Two areas, one day each, plus a loose half-day.
Haeundae and Gwangalli (east). Haeundae is the big city beach, ringed by high-rises. It’s lively, easy, and packed in July and August. Walk east along the coast toward Mipo and Cheongsapo when the beach itself gets too busy. Gwangalli, a short ride west, is the better evening: a smaller beach facing Gwangan Bridge, which is lit at night, with bars and raw fish restaurants along the front. If you only have one sunset in Busan, have it here.
Nampo-dong, Jagalchi and Gamcheon (south and west). This is old Busan, near Busan Station. Jagalchi is the city’s big fish market. The usual move is to choose seafood at the stalls and have it prepared at a restaurant upstairs. Nampo-dong around it has street food, shops and the BIFF Square stalls. Gamcheon Culture Village is a hillside of painted houses a bus or taxi ride away. It’s photogenic and genuinely crowded by late morning, and it’s a place where people live, so go early and keep it quiet.
Day 7. Either a slow morning at the beach before your flight, or Haedong Yonggungsa, a seaside temple north of Haeundae. It’s lovely and very busy, and it takes a chunk of time to reach by public transport. Skip it if your flight is early.

Getting around Busan
Busan has a subway, buses and plenty of taxis, and it all takes the same card you used in Seoul.
| Card | Works in Busan? |
|---|---|
| T-money (plastic or Apple Wallet) | Yes, subway and buses |
| WOWPASS (its T-money part) | Yes |
| Seoul Climate Card | No, Seoul only |
A short subway ride costs 1,600 won by card, after Busan’s fares rose in 2024. Top up your T-money with cash at convenience stores or station machines, the same as in Seoul. If you bought a Climate Card pass, time it to end the day you leave Seoul (our transit card guide explains how passes run).
Busan also has BusanPay, an app and prepaid card for foreign visitors that combines payments with 1-day and 3-day subway QR passes. It’s an option if you’ll ride a lot, but plain T-money is simpler for a three-day stay.
Taxis do a lot of work in Busan because of the hills. For Gamcheon and Haedong Yonggungsa in particular, a taxi can save a lot of time.
What to do with your luggage
This is the part people forget to plan.
- Pack light for Busan. If you’re coming back through Seoul anyway, many Seoul hotels will hold a bag for a few days if you ask. Leave the big case, take a weekender.
- Send bags ahead. Luggage delivery companies run counters at Busan Station, major KTX stations and airports. You can drop your suitcase in the morning and have it sent to your hotel, so you can sightsee on arrival day without it.
- Station lockers. Big stations have lockers, but the large sizes go fast on weekends. Don’t build your day around finding a free one.
Mistakes that cost time
- Two hotel changes in Busan. Pick one base. Busan is too spread out to move twice in three days.
- Planning Haeundae and Gamcheon on the same day. They’re on opposite sides of the city.
- Booking the KTX on the day on a weekend. Popular trains sell out.
- Going back to Incheon for the flight home. If you must, budget most of a day: a two-plus-hour KTX to Seoul, then the airport train, then up to three hours early at the airport in peak season.
- Bringing the Climate Card to Busan. It won’t open the gates.
What we’d do
First trip, one week: four Seoul days with a day trip on day four, a morning KTX on day five, a Haeundae base, and the flight home from Gimhae.
Food-first travelers: stay near Nampo-dong or Seomyeon in Busan instead of Haeundae. You’re closer to Jagalchi, the markets and late-night eating.
Traveling with kids or older parents: use luggage delivery on train day and take taxis in Busan. The hills are real.
Only six days: cut the flexible Seoul day, not a Busan day. Busan is better with time to slow down.
Questions people ask
How much is the KTX from Seoul to Busan?
About 54,000 won for a standard adult seat since September 1, 2026, when KTX fares were cut about 10% after Korail and SR merged operations. The old fare was 59,800 won.
Is four days enough for Seoul?
For a first trip, yes. Three days covers the main clusters, and the fourth gives you a day trip or a slower neighborhood day.
Does my Seoul Climate Card work in Busan?
No. It only covers Seoul. A T-money card, including the T-money inside WOWPASS, works on Busan's subway and buses.
Do I need to book the KTX in advance?
On weekends and holidays, yes, because seats on popular times sell out. On weekdays you can often buy a few days ahead, but booking early costs nothing.
Should I stay in Haeundae or near Busan Station?
Haeundae if you want the beach and a resort feel. Near Busan Station or Nampo-dong if you want the old downtown, markets and an easy train out.

Busan or Jeju for a short trip? An honest comparison
One is a big port city you can reach by train and explore by subway. The other is an island that rewards a car. Which one fits depends on how you like to travel.
