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.
Asan is a small city in South Chungcheong, about 1.5 hours from Seoul by train, built around Onyang Hot Springs, the oldest spa site in Korea, and Hyeonchungsa, the shrine of Admiral Yi Sun-sin. Sights are spread across a wide area and the city is quiet after dark. Most travellers come for a spa night or as a stop between Cheonan and Daejeon; two nights is the ceiling unless you are hiking.

Arrive & move
Airports are listed under At a glance; this is how to move once you are in
Getting around
Seoul Subway Line 1 runs through five Asan stations (Asan, Tangjeong, Baebang, Onyangoncheon, Sinchang), so the rail spine is easy. Between sights, use city buses or taxis; buses are infrequent and many temples and mountains need a taxi from the nearest stop. Public bicycles rent at Gokgyocheon and Sinjeongho lake for ₩1,000–2,000 for two hours (closed Mondays).
