Saunas

Korean saunas or jimjilbang are wonderful. That is, if you like to sweat and lay around and then hop in a hot tub or cold tub. The sauna sections are co-ed and usually have a few rooms to choose from with different ambience or healing materials (salt, ochre, charcoal). Some saunas are open 24 hours so many travelers use them as a cheap place to spend the night (you can sleep/nap in the common lounge room). To use the sauna you are given an outfit of shorts and shirt to sweat through, which is great and comfortable. But eventually that strange odor of steam and sweat soaked cotton starts to kick like a old towel and that's a good sign you've had enough. The towel on the head is optional and this is the way to wear it, I usually do something more turban like.

I visited "spa land" in Busan, it's the largest jimjilbang in the country and caps the visit at 4 hours, but it was long enough and really great. The highlight was the outdoor hot springs. It's a fancy place, totally touristy, and if I'm in Busan I will go again.
