Hongseong홍성군
Give Hongseong one night as a west-coast stop: Namdang Port oysters and a Yongbongsan or Oseosan hike. Without a car, skip it.
Hongseong is a county of about 99,000 people on South Chungcheong's west coast, 444 km² of low mountains, tidal bay and farmland. Trains and buses from Seoul, Daejeon and Gwangju reach it in 1–2.5 h, but the sights — Namdang Port, Yongbongsan, Oseosan, Gwangcheon — sit 10–30 km apart, so a car decides whether the stop works. Most travellers pass through on the way to Buyeo or Boryeong; one night is enough if you have wheels.

Rules in force · 5
- East Asia ↗Every border in East Asia is a full international border, Hong Kong and Macau included: an entry permission for one never covers the next.
- East Asia ↗Ferries between Korea, Japan and China cancel in rough seas and typhoons; keep a flight or a spare day behind every sea leg.
- South Korea ↗Check K-ETA and visa status on the official sites before you fly; the list of nationalities exempted from registering online changes year by year.
- South Korea ↗Google Maps gives poor walking and driving directions in Korea; use Naver Map or Kakao Map for routes.
- South Korea ↗Buy a T-money card (or use a phone-based transit pass) for subway and buses; it also pays at convenience stores and many taxis.

Getting around
A car is the practical choice: attractions are 10–30 km apart and rural buses are infrequent. Hongseong-eup itself is walkable — station, terminal, market and shops sit within about 1.5 km. Local buses link the town to Gwangcheon and Namdang Port but run a few times a day; check times at the terminal. Bicycle paths and rentals exist around town. Taxis are metered and cheap for short hops.
