There is a peculiarly Korean activity and it is to spend the night in a sauna.
It’s not quite what you’re thinking. For one, you’re not literally in the sauna itself . . . unless you want to be. And secondly . . . it’s not remotely dodgy.
Jimjilbangs, as they’re known, are essentially bathhouses, and you’ll find them in every city, town and village throughout the country – although most are significantly smaller than the one I visited. They’re open 24/7 and you can enter or leave whenever you want, which makes them the ideal crash pad for exhausted office workers or late-night clubbers or just a safe, friendly space for a gang of friends to spend an evening. I knew I had to experience this before leaving and had heard good things about Siloam in Seoul: not as glitzy or touristy as the much-touted Dragon Hill Spa, but still attended by enough foreigners that there would be some English instructions, and my flabby white body wouldn’t receive too many curious/disgusted glances.
