Ansan is a city south of Seoul. Located on the blue subway line #4 it takes about 1 hour to get to Seoul. Jungang-dong is the main town area of Ansan, while the area around Ansan Station has alot of South Asian immigrants who work in the factories. It is known as an industrial area, but there are a growing number of Westerners living here to teach English.

If you really must go to Uijongbu a great place to stay is the Come On Inn. For about $40 a night you get a big screen tv, a massive bathroom. And one can even try the upgraded room for $60 a night with a great balcony and bar area in the room. Also, dont forget to try out the famous Budae Jigae which is a soup made famous in that area.

I love walking around the Fortress Wall. You could spend a day walking around the whole thing, although I only did half and came back to finish the rest.
Suwon Folk Village (30 mins by bus from the train station) is also great. You could easily spend a day there, too.

Connected to Seoul by bus route and subway! Home of the International Airport in S. Korea. Visit Chinatown and see a statue of MacArthur.

Incheon's Chinatown is worth a day-trip, but the food is pricey, and more Korean than Chinese. For a really great time in Incheon, check out the Arts Center, where you can catch a movie at CGV, grab a bite of either Western or Korean food, or explore the local venues to find theaters and live music performances.

I went see Suwon Fortress. It was amazing and deffiniatly worth the trip. Outside the bus station is the Tourist Information and its very helpful to get around. Great photos, and a beautiful place. I highly suggest it

A trip to Panmunjom is essential if you go to Seoul - seeing the DMZ up close is quite amazing - the North Korean guards staring at you through the windows of the negotiation building is as close as you will get to North Koreans without going to Yanbian, China or Central Asia, unless you go to the DPRK itself... I went there only once, on my first trip to Seoul, but I hope to go back sometime when I am in Seoul and not so busy as I usually am there!

Great samgyetang! And good views of DPRK as well

Hannam has the best foreign market in Seoul.  Go to Hangangjin Station (항강진역) and leave through exit 2.  Head straight under the highway.  Cross the footbridge and follow the street right.  Look for a Volvo building on your left.  Head downstairs and you're there!  Be sure to check all three markets in this building for what you want.  There is one large one, one that is like a small deli, and one that looks more like a gas station market than anything else (but they have some great ingredients that you can't find anywhere else.  Almond extract for instance.).

There is not much to see in Inchoen, go to Seoul!
