Salt air, squalls, and seasonal blooms define Korea’s edges. Busan stacks ports, temples, and ridges; Jeju spreads volcanic fields and orchard windbreaks. Build slack into ferry and domestic flights—marine fog delays happen.
Coast & islands
Busan vs Jeju pacing
Busan suits train-linked trips from Seoul with nightlife and dense neighborhoods. Jeju wants wheels (rental or tour van) for anything beyond the airport belt unless you enjoy long rural buses. Neither is “just beach”: both reward hikers and market eaters.
Seafood literacy
Live tanks and sannakji-style dishes are famous; choose vendors with clear prices per kg. Learn the difference between 회 (raw slices) and 구이 (grilled). If unsure, point at a set menu and nod — still confirm the bill before cooking starts.
Weather realism
Typhoon season and spring yellow dust alter outdoor plans. Jeju’s wind famously pins hats; Busan’s humidity spikes in August. Pack a shell layer even in summer for ferry decks.
Island driving & safety
Jeju rental rules require proper license classes; international permits may need verification. Rural roads have blind curves—use turnouts. Swim only at flagged beaches; rip currents are serious.
Coastal culture notes
Regional accents and slang thicken away from Seoul; listen more than you mimic. Temples on cliffs (Haedong Yonggungsa style) mean stairs—respect quiet zones and photo bans indoors.
