I Planned My Trip Around a K-Drama Location. Zero Regrets.

There is a version of the South Korea trip that is purely about K-pop and K-dramas — the filming locations, the idol cafes, the HYBE building in Gangnam. That trip is completely legitimate and extremely well-catered for. But South Korea also happens to contain Gyeongbokgung Palace, the DMZ, the most atmospheric fish market in Asia, and a hillside city painted in every colour, and a week that starts with K-culture and follows the KTX south ends up being something larger than the reason it started.

The Route

Seoul runs for three days, which is the minimum to understand the city without just scratching the surface. The DMZ uses the fourth day. The KTX bullet train south to Busan takes 2.5 hours on Day 5, and Gyeongju — the ancient capital of the Silla Kingdom, a city that is essentially a living museum — closes the week as a day trip from Busan before the flight home.

Days 1–3: Seoul

Seoul shifts personality district by district in a way that no other Asian city quite matches. Myeongdong is bright and loud and smells of tteokbokki. Bukchon is a hillside of 900 traditional wooden houses still inhabited by the same families who have lived there for generations. Hongdae is a university neighborhood that runs on independent music and the kind of cheap food that only exists because students need to eat. Gangnam is the postcode that made the song inevitable and the entertainment industry that made the culture global.

Gyeongbokgung Palace anchors the first morning — 600-year-old royal architecture on the scale of a small city, with the Changdeokgung Secret Garden and Bukchon immediately behind it. Rent a hanbok at the gate; you enter free and photograph far more interestingly.

Day 3 is the Han River, the park system that Seoul built along it as communal living space, and Itaewon — a neighborhood that has been reforming its identity from military-base-adjacent into something more genuinely interesting for the last decade.

Day 4: The DMZ

An hour north of Seoul, the 4km-wide strip of land that has separated North and South Korea since 1953 is the most geopolitically charged day trip in the world. The Joint Security Area at Panmunjom is where North and South Korean soldiers stand facing each other across a line painted on concrete. The Third Tunnel was dug by North Korea under the DMZ in the 1970s — visitors can walk in. The Dora Observatory gives the only sanctioned view into North Korean territory from the South Korean side.

It is not a cheerful day. It is an essential one.

Days 5–6: Busan

Busan from the KTX is a city that comes in fast. Gamcheon Culture Village — the community of brightly painted houses built by Korean War refugees on a hillside when the flat land ran out — is the photograph, but the city underneath it is genuinely its own thing: Jagalchi Fish Market, Korea's largest, where you pick your own seafood from a tank and eat it upstairs. Haeundae Beach with a skyline behind it. Haedong Yonggungsa Temple built directly on the sea cliffs. Gwangalli Beach at night with the bridge lit up behind it.

Day 7: Gyeongju

The Silla Kingdom ruled most of the Korean peninsula for nearly a millennium, and Gyeongju was its capital. The burial mounds of its kings — enormous green hills sitting in the middle of a modern city — are called Tumuli Park. Bulguksa Temple, built in 751 AD and never entirely destroyed, is a UNESCO site and one of the finest examples of Korean Buddhist architecture. The city is an hour from Busan by KTX and an easy final morning before the flight home.

A Few Things Worth Knowing Before You Go

South Korea's K-ETA (Korea Electronic Travel Authorization) is temporarily suspended for US, UK, EU, Canadian, and Australian travelers through December 31, 2026 — meaning most Western visitors currently need no advance authorization. From January 1, 2027, K-ETA will be required: ~$7-8 USD, apply at k-eta.go.kr at least 72 hours before departure, valid for 2 years. Separately, the e-Arrival Card is now mandatory for all visitors — complete it at e-arrivalcard.go.kr within 72 hours before arrival (not earlier — it expires). Pick up a T-money rechargeable card at Incheon Airport the moment you land; it works on every subway, bus, and taxi across Seoul, Busan, and Gyeongju. Download Naver Maps rather than Google Maps — Korean public transport routing is significantly more accurate on Naver. The same applies for Kakao T over Uber for taxis.
