Unless you’re a passionate fan of spelunking, you might think that caves are boring. After all, they’re dark, wet, narrow, and probably full of bats – who are known carriers of dangerous diseases, among other things – and that’s pretty much about it, right? No? If you are one of those people who agree with that statement, then let me try to change your mind because there is one area in the Czech Republic known for its fascinating caves. It lies in the middle of beautiful forests that look like from brothers Grimm’s fairy tales. But don’t worry – there are no evil old witches lurking within!
