1) Seoul — Modern culture, palaces, nightlife (7 days)
South Korea’s capital is half the country’s population and the center of everything: food, fashion, K‑pop, history, and nightlife. Must‑see highlights:
Gyeongbokgung Palace (changing of the guard ceremony)
Bukchon Hanok Village & Insadong
N Seoul Tower (sunset views)
Hongdae & Myeongdong (shopping + street food)
Euljiro & Itaewon nightlife
DMZ day tour (powerful historical experience)
Why 7 days? Seoul has enough to fill a week without rushing — museums, markets, neighborhoods, and day trips.
2) Busan — Beaches, seafood, ocean temples (3–4 days)
A southern coastal city with a relaxed vibe and amazing food. Must‑see highlights:
Haeundae Beach
Gamcheon Culture Village (colorful hillside art village)
Haedong Yonggungsa (temple by the sea)
Jagalchi Fish Market
Busan Skywalks & coastal trails
Why go? It’s the perfect contrast to Seoul — slower, ocean‑focused, and full of character.
3) Gyeongju — Ancient Korea & UNESCO sites (2–3 days)
Often called “the museum without walls.” Must‑see highlights:
Bulguksa Temple (UNESCO)
Seokguram Grotto
Tumuli Park (royal tombs)
Cheomseongdae Observatory (oldest in Asia)
Why go? It’s the best place to understand Korea’s ancient history and architecture.
4) Jeju Island — Volcanoes, beaches, waterfalls (6–7 days)
Jeju is Korea’s tropical island — volcanic peaks, lava tubes, beaches, and dramatic cliffs. Must‑see highlights:
Seongsan Ilchulbong (Sunrise Peak)
Hallasan National Park (Korea’s highest mountain)
Manjanggul Lava Tube
Jeongbang & Cheonjiyeon Waterfalls
Black‑sand beaches
Coastal drives & cafés
Why a full week? Jeju is bigger than people expect — each side of the island feels different.
