Major city · South Korea
Siheung시흥
Skip Siheung as a base: it is a Seoul satellite with no old town. Go only for Oido's mudflats and sunset, as a half-day from Incheon or Ansan.
Siheung is a southwestern Gyeonggi satellite of about 425,000 people, grown from 100,000 in the 1990s around the Sihwa industrial complex. Its draw is coastal: the Oido shell-mound site, the red lighthouse and the West Sea sunset, plus the Siheung Gaetgol Ecology Park. Sights are spread over roughly 140 km², so a car or a taxi hop matters more than a metro pass. Most travellers see it as a half-day add-on to Incheon or Ansan, not a place to sleep.

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
The Seohae Line (Sosa–Wonsi) is the backbone, with Siheung City Hall, Siheung Neunggok, Wolgot, Oido and Jeongwang stations; Line 4 and the Suin–Bundang Line touch the edges and need a transfer. City buses (510, 23, 88) link the districts and the coast; wide-area 3400 and 3200 run to Gangnam and Yeouido. Bikes are easy to rent near Wolgot and Jeongwang stations. Taxis start at about ₩4,800.
