⚠️ Essential Travel Tips Seoul
Google Maps Doesn't Work
Due to national security laws regarding North Korea, Google Maps cannot provide walking or driving directions. You absolutely MUST download 'Naver Map' or 'KakaoMap' to navigate.
Get a T-Money Card
Immediately buy a T-Money transit card at a convenience store. It is essential for tapping on and off the massive, excellent subway and bus network.
Free Palace Entry
If you rent a traditional 'Hanbok' (Korean dress) from a shop outside the main palaces (like Gyeongbokgung or Changdeokgung), your entry into the palace is completely free.
Eat Chimaek
The Korean holy grail: Chikin (Korean fried chicken) and Maekju (beer). Head to the Han River parks in the evening and order it delivered right to your picnic blanket.
