I used to just take the subway wherever I go, but when I had my son riding a bus seems easier. Subways here are about two to four levels below and some don’t have escalators and elevators. Imagine carrying a child and having to climb two or three flights of stairs. The best thing about public transportation here is that you sometimes won’t have to pay separately when you go from the subway to bus or vice versa, as long as you have a transportation card (교통카드) and you transfer within 30 minutes.
While there are English signs on the bus, the map route at the bus stops are only in Korean. An easier way to find the bus that you need to take is through the Seoul bus route map. On the left of the website is a panel for you to input the departure and destination points. You can just type the name of the place and search. If there are similar names then you’ll have to choose which one it is. The result will show the number of the bus that you should take and where you should transfer if necessary.
