Why trust this guide

Busan is Korea's second city and its opposite number to Seoul — a coastal port built into steep hills, wrapped around beaches, with a rawer, saltier character and the largest seafood market in the country. Two and a half hours from Seoul by fast train, it is the easiest and best add-on to a Korea trip and increasingly a destination on its own.

Why it's worth the flight

It's the only major Korean city with real beaches, and the combination of mountains, sea, temples on cliffs and a dense working port makes it far more visually varied than Seoul. It's also noticeably cheaper and more relaxed.

When to go

Late spring and early autumn are ideal. Summer is when Koreans descend on the beaches — hot, humid, crowded and lively, with monsoon rain in July. Autumn is clear and comfortable. Winter is cold but milder than Seoul and the seafood is at its best.

Where to base yourself

Go for the fish Jagalchi is Korea's biggest seafood market. Choose from the tanks downstairs and they cook it upstairs — this is the meal to plan your day around.

What to eat

Seafood above all: raw fish (hoe), grilled shellfish, and eomuk fish cakes, a Busan speciality. Dwaeji gukbap, pork and rice soup, is the local comfort dish born of the Korean War. Milmyeon, cold wheat noodles, is another Busan original. And ssiat hotteok, the seed-stuffed sweet pancake, from a street stall in Nampo-dong.

Getting around

The subway covers the city well and the same transit card from Seoul works here. Buses fill the gaps up the hills. Taxis are cheap. Busan is spread out along the coast, so plan by area rather than criss-crossing.

Add it to a Korea trip

The stopover logic

Two hours by train from Seoul makes Busan the easiest second city in Asia to add. Building the routing well is a skill worth having.

The honest caveat

Busan is sprawling and hilly, so it takes more time to move around than its size suggests. It has fewer conventional sights than Seoul and works best as a two or three-day counterpoint rather than a week on its own.
