Almost everyone who plans a first trip to South Korea runs into the same question: Seoul or Busan, or both? The two cities are only a few hours apart by train, but they feel like they belong to different countries. I lived in Seoul for eight months as an exchange student in 2020, in the student district of Sinchon, and I still go back every year. I have also been to Busan three times, in 2018, in 2020 and again in June 2026, and after my last trip I wrote a complete Busan travel guide. So I have seen both cities as a resident and as a visitor, and my answer depends on how many days you have.
Seoul or Busan? How to Split Your Time Between Korea's Two Biggest Cities
In this guide I compare the two cities on the things that matter for a trip, from atmosphere and food to shopping and getting around, and then suggest how to split your days.
Seoul and Busan at a glance
- Distance: about two and a half hours by KTX high speed train, around 60,000 won one way.
- Seoul is best for: palaces, neighbourhoods, nightlife, endless food and a first look at Korea.
- Busan is best for: beaches, seafood, a cliffside temple and a slower pace.
- My split for 7 days: four days in Seoul, three in Busan.
Two Very Different Cities
Seoul is huge. Around ten million people live in the city itself, and the metro area is far bigger. It is fast, efficient and always busy, with a neighbourhood for every mood. When I lived there, I loved that I could take the subway in any direction and find a completely different side of the city within twenty minutes. But Seoul also asks a lot of you. Everyone seems to be in a hurry, and after a week of crowded trains and long days you notice it.
Busan is Korea's second largest city and its biggest port, and it is built around the coast. Mountains run right into the city, so neighbourhoods climb up the hills and beaches sit just a few subway stops from the centre. People speak a stronger regional dialect that can sound rough at first, but in my experience they are relaxed and generous. Every time I arrive in Busan from Seoul, the trip suddenly slows down, in a good way. And for shoppers, the city centre easily keeps up with Seoul: my guide to shopping in Seomyeon lists the stores I think are worth your time.
What Seoul Does Better
- History and culture: the royal palaces, traditional hanok streets and big museums are concentrated in Seoul.
- Variety: student districts, design neighbourhoods, markets and skyscrapers. You will not run out of areas to explore.
- Nightlife: Hongdae and the areas around the universities stay busy until the early morning.
- Food choice: there is simply more of everything, from Korean classics to food from all over Asia.
My own Seoul was Sinchon, a lively university district next to Hongdae. It is cheap, young and full of small restaurants. One of my go-to meals there was mala xiang guo, the spicy Chinese stir fry where you pick your own ingredients from a buffet and pay by weight. It sounds like an odd choice in Korea, but in student areas like Sinchon it is everywhere and very popular. That is Seoul in a nutshell: you can eat almost anything, any time.
What Busan Does Better
- The coast: real city beaches like Haeundae and Gwangalli, with a lit up bridge over the bay at night.
- Seafood: Busan is a fishing city, and the markets are part of daily life, not just a tourist attraction.
- A temple by the sea: most Korean temples sit in the mountains, but Haedong Yonggungsa is built on the rocks above the water.
- A slower rhythm: long evenings by the water instead of rushing from sight to sight.
Food is where Busan really stands out for me. My favourite dish there is milmyeon, Busan's version of cold noodles. The broth arrives half frozen, and the staff cut the long noodles with scissors right at the table. I order it on every visit. At Jagalchi, the big fish market by the harbour, I had grilled eel, which I actually prefer to the sweet eel you get in Japan, and I also tried live octopus. Chew it well and dip it in the sesame oil sauce. A friend from Busan recommended Millak fish market to me as a more local alternative to the big tourist markets, with less risk of being overcharged. And in the evening, nothing beats Korean BBQ with samgyeopsal and a somaek, beer mixed with soju.
Shopping: Seoul or Busan?
Most people assume Seoul is the only place to shop in Korea, but Busan surprised me. The centre of Busan is Seomyeon, where the two main subway lines cross. It has Korean fashion chains, big department stores, beauty shops and a long underground arcade full of small shops with lower prices than above ground. On weekends dance crews perform K-pop routines on the main street, and the whole area feels young and lively.
Seoul has more choice overall, especially for independent designers and vintage. But if your time is short, you can do all your Korean fashion and skincare shopping in Busan and spend your Seoul days on the palaces and neighbourhoods instead. One tip for both cities: always carry your passport when you shop, because you need it for the tourist tax refund.
Getting Between Seoul and Busan
The easiest way is the KTX high speed train from Seoul Station to Busan Station. It takes about two and a half hours and costs around 60,000 won one way. Trains run all day, and the stations are central in both cities, so you go from city centre to city centre without any airport transfers. Book ahead for weekends and Korean holidays, when trains fill up.
Domestic flights from Gimpo Airport in Seoul to Gimhae Airport in Busan are short, but once you add the trip to the airport and security, the train is usually just as fast and much easier. Busan also has its own international airport, so it is worth checking whether you can fly into one city and out of the other. That saves you the trip back.
How to Split Your Days
| Trip length | My suggestion |
|---|---|
| 3 to 4 days | Choose one city. Seoul for a first visit, Busan if you have been to Seoul before or want a beach trip. |
| 5 to 6 days | Three or four days in Seoul, two in Busan. Take an early train south to make the most of your Busan days. |
| 7 days | Four days in Seoul and three in Busan. This is the split I recommend most. |
| 10 days or more | Five or six days in Seoul and four in Busan, or add a few days elsewhere in Korea. |
If this is your first time in Korea, start in Seoul and end in Busan. Seoul gives you the big picture of the country, and Busan is the perfect place to slow down before you fly home. If you have already been to Seoul, I would give most or all of your days to Busan. My Busan travel guide, linked at the top of this article, covers things to do, where to stay and how to get around once you are there.
So, Seoul or Busan?
If you can only choose one, pick Seoul for your first trip and Busan for your second. If you have a week, do both. After many trips, Seoul is the city I lived in, but Busan is the city I keep wanting to go back to. Its mix of mountains, sea, markets and slow evenings is something Seoul cannot offer, and for many travellers it ends up being their favourite part of Korea.
