Jjimjilbang!!!

After the rock festival I headed to Seoul where I went to a Jjimjilbang (찜질방), to have a nap, shower, and get a body scrub. If you don't know about Korean saunas, it's definitely an experience!
What it is: Public bathhouse
How much: 8,000-12,000 won
How it works: You walk in to the building and pay. The attendant will give you a small towel, pajamas, and a locker key. The first locker will be small, only for your shoes. Then you will enter the gender segregated area where you will find big lockers for all of your belongings. By this point you will notice many naked Korean women (or men if that's what you are) and children walking around. You should put all of your clothes and belongings into your locker and take a shower. You can buy everything you need (shampoo, soap, etc.) from the attendant. You can get a massage, body scrub, or just relax in a steam room, dry sauna, or different temperature spa. It can be really fun and relaxing! When you are done showering, you can put on pajamas and find a mat to sleep on. It's definitely one of the cheapest ways to get some sleep after a night out in Seoul. But beware, the temperatures in these places can be pretty hot, and with a pretty thin mat to sleep on can be rough if you are a light sleeper.
