I've mentioned before that I'd do this in my travelogue entries and also doing this just in case anyone needs help to survive in Seoul lol.
Please note that all these are based on my own personal experience so what may work for me, may not work for you.
Peace y'all and have fun in Seoul! :D
1. Download the Seoul subway map onto your phone
Honestly speaking, I really dislike taking the subway in Korea because it's so freaking complicated!
Take a look at this map:
9 lines all together. Plus this is just Seoul alone (ok, you can get to Incheon too). And you say Singapore's MRT lines are bad?!
So while we were there, I was constantly trying to figure out which station we had to switch trains at etc until I downloaded this app from the app store because it was driving me crazy alighting at the wrong stations and wasting so much time. Time is so precious especially when you're on vacation no? Agreed right lol.
The app is called 'Subway Korea' and totally free.
How the app looks like and please admire my GRi background too xD
