Getting around Seoul

There are 4 ways to get around Seoul
1. Subway
2. Train
3. Bus
4. Taxi

of course you can also walk. 

However, according to forum posts, there are several locations in Seoul which are quite hilly. 

So, be prepared and I hope you choose comfort over fashion. 

I am thinking that I'll be doing lots of walking here. (Thank you, UP. Those days where I was so stingy and just walked instead of riding a jeepney in between classes prepared me for this moment...)

Subway
I think this is the latest map of subways they have.

It would be better if you print this out on a large size paper. I think you can request copies of these. 

Here's also a link on how to buy those transportation passes that they use.

Bus

I think riding the bus should be left to those people who have been to Korea for quite some time. Just reading about the schemes is enough to get me confused and that's not including those buses that goes around in a loop. You might end up lost in a remote part of the country. 

For those with intestinal fortitude, may the link below serve a reference in understanding the system

Incidentally, I was thumbing through google maps on my smartphone and wonder of wonders! They provide bus schedules! Hmmm, this makes it doable then. 

Train

I suppose you can also ride the train if you want to visit other parts of Korea. Please check schedules at the KORAIL website. They say that you can purchase tickets up to one month before the schedule. 

Taxi

Riding a taxi (again according to forums) becomes cheaper if the destinations are 3 to 4 stations away and you are a group of 4. They say that it would then be cheaper than using the subway. 

I suppose you also have to consider rush hour.
