Which one suits you

One day in Seoul against one day in Jeju

• Morning: in Seoul, Gyeongbokgung at opening, timed to catch a changing of the guard, then up the hill into Bukchon Hanok Village; in Jeju, Seongsan Ilchulbong at sunrise, which is about 25 minutes up to the crater rim.
• Midday: in Seoul, Gwangjang Market: sit at a stall, point at what the next person is eating, repeat; in Jeju, a haenyeo village nearby for whatever has just been landed, bought from the divers themselves.
• Afternoon: in Seoul, Ikseon-dong's hanok alleys, which are Bukchon's charm without the signs asking you to be quiet; in Jeju, Manjanggul lava tube: a kilometre of cold, dark, genuinely strange walking.
• Evening: in Seoul, Hongdae for buskers, cheap food and a noraebang if the night heads that way; in Jeju, back to Jeju City for black pork over charcoal, with anchovy sauce rather than the mainland's ssamjang.

Slot by slot from each guide's one-day plan; the full Seoul and Jeju itineraries go to five days.
