Busan
Busan is worth 2-3 days, ideally as an add-on to Seoul via the 2.5-hour KTX train (about $44 one-way). It's Korea's second city and largest port — a coastal city of 3.4 million with a genuinely different character from Seoul: beaches, mountains meeting the ocean, colorful Gamcheon Culture Village, and Jagalchi, the country's biggest seafood market. Many travelers who visit both cities end up preferring Busan's slower, saltier atmosphere.
Busan gets pitched as 'a smaller Seoul,' and that undersells it completely — this is a city shaped by the sea and stacked into hillsides, with a personality that's looser, prouder, and noticeably more local than the capital.
How many days in Busan?
Two to three days covers the essentials well: one for Haeundae Beach and the coastline, one for Gamcheon Culture Village and Jagalchi Market, and a spare half-day for whichever neighborhood pulled you in. It pairs naturally onto the end of a Seoul trip via the KTX bullet train.
What to see
| Attraction | What it is | Time needed |
|---|---|---|
| Haeundae Beach | Korea's most famous beach, 1.5km of sand backed by skyscrapers | Half a day |
| Gamcheon Culture Village | Pastel-painted hillside houses, murals, art shops — 'the Santorini of Korea' | 2-3 hours |
| Jagalchi Market | South Korea's largest seafood market — pick your own catch, have it cooked upstairs | 1-2 hours |
| Gwangalli Beach & Diamond Bridge | The best skyline view in the city, especially once the bridge lights up at night | An evening |
Jagalchi Market is best experienced early morning (it opens at 5am) when the freshest catch has just come in from Busan Port, though it runs until 10pm daily if mornings aren't your style.
Getting there from Seoul
The KTX high-speed train covers Seoul to Busan in about 2.5 hours for roughly $44 one-way — genuinely one of the easiest, most comfortable domestic legs anywhere in Asia. There's no need to rent a car; book tickets a day or two ahead in peak season (summer, major holidays) to guarantee a seat.
Busan or Seoul — how much time in each?
If you only have 5 days total, spend them all in Seoul. With 6-7+ days, a 4-Seoul-plus-2-to-3-Busan split works well. See our full comparison for a direct breakdown.
