I think there's something about the way you go into a tunnel, travel down it, and emerge somewhere else. They almost have a hint of magical matter transportation to them, ridiculous as it seems. That's what makes tunnels in particular more exciting than mere mines or caves. I can make a cave system immediately more intriguing if I tell you that if you go through the system of caves you can emerge somewhere completely different.
