What you'd actually do
A few of each guide's picks, one per category before seconds — the full lists are on the guides themselves.
🇰🇷 Busan
Korea's port city and second capital — beaches at the end of the metro line, a hillside village painted every colour, and the country's best raw fish. Slower and warmer than Seoul in every sense.

🇰🇷 Jeju
A volcanic island south of the peninsula with its own dialect, its own myths and a dormant peak in the middle of it. Korea's holiday island — hiking, lava tubes, black rock coastline and women who free-dive into their eighties.
