TRAVEL
There are two international airports in Seoul. Most of you will come through ICN.
  1. Incheon International Airport (ICN)
    There are two recommended ways (airport limousine bus, subway) to come to SIM from ICN. The best way will be the airport limousine bus.
  2. Gimpo International Airport (GMP)
    There is only one recommended way (subway) to come to SIM from GMP.
The subway option always starts with the airport express train (AREX) (sometimes it's called Airport Railroad Express), which is a part of the whole subway system of Seoul, from each airport. Therefore you only need one ticket to come to Sinchon subway station (240).

Taxi (from both airports) is always a feasible solution and but it's not recommended at all unless you have no other options.
For detailed info on how to come to SIM from the airports, please read this guide page (PDF).

Here is also a PDF file saying "you want to go to 1) SIM, 2) Yonsei univ. main gate, 3) Somerset Palace Seoul" in Korean. You may print this out and carry it just in case you need to ask some local people for help.
