서울은 대중교통체계가 잘 갖춰져 있어 대중교통만 이용해서 충분히 여행이 가능하다. 특히 환승 시스템이 잘 갖춰져 있다. 버스와 지하철 사이에 환승이 가능하며 하차 후 30분 이내에 최대 4번까지 환승이 가능하다. 하지만 같은 노선(같은 번호 버스, 같은 노선 지하철)은 환승이 불가능하니 참고하자.
Seoul has a well-developed public transportation system, allowing for sufficient travel using only public transit. The transfer system in particular is well organized. You can transfer between buses and subways, and you can transfer up to 4 times within 30 minutes after getting off. However, transfers are not possible on the same line (same number bus, same subway line), so keep that in mind.
