Just arrived in Suwon for a couple of months and i can’t wait to try! I loved going to onsen in Japan (especially Kurama, in the woods outside of Kyoto), it looks quite similar. Oddly enough, when I mentioned the idea to my Korean girlfriend, she looked quite embarrassed… I won’t forget to buy a small towel before :).
Great blog, thank you.

P.S. : when do you intend to write a “best spots to go climbing in Korea”? 😉
