Udo Island

Take a 30‑min ferry from Seongsan (Jeju) and spend a day biking or bus‑touring Udo; no overnight stay needed.

Not yet checkedSourcesWhat these labels mean

Udo Island is a 3.5 km offshore lava plateau with beaches, peaks and a sausage street. A ferry from Jeju runs every 30 minutes (9:00‑17:00). The island is small enough to see by bike (13 km loop) or the 1,000 won tourist bus, so one day is sufficient.

This is a basic guide for Udo Island: no airport-to-bed path, walking clusters or day plans yet. Fares and schedules here are unverified. What this page does cover
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.

Entry rules depend on your passport. Full visa guide
